Zeichenfolgen müssen in Abfragen immer in einfache Anführungszeichen gesetzt werden, z. All SQL used by the file geodatabase is based on the SQL-92 standard. Pro SDK. You will need to use SQL when you construct an expression for many geoprocessing tools, including: Select Layer By … The result is an exact numeric with an implementation-defined precision and a scale of zero. Check one or more of the following filters and set one of them as the default by clicking Make default:. The string shown in the SQL query may only slightly resemble the value shown in the table, especially when time is involved. A scalar subquery returns a single value. Returns the arcsine of float_exp as an angle, expressed in radians. TRIM(BOTH | LEADING | TRAILING trim_character FROM string_exp). A basic SQL WHERE clause would look like. The SQL … If integer_exp is negative, numeric_exp is truncated to |integer_exp| places to the left of the decimal point. In addition to the operators below, enterprise geodatabases support other capabilities. Geodatabase data sources store dates in a date-time field. Abfrageausdrücke werden in ArcGIS verwendet, um eine Teilmenge von Features und Tabellendatensätzen auszuwählen. For example, this query returns numbers that begin with 8 from the integer field SCORE_INT: To include the percent symbol or underscore in your search string, use the ESCAPE keyword to designate another character as the escape character, which in turn indicates that a real percent sign or underscore immediately follows. Procedure. Greater than or equal to. All query expressions in ArcGIS Pro use Structured Query Language (SQL) to formulate these search specifications. It can be used to apply predicate or aggregate functions or to compare data with values stored in another table. Strings must always be enclosed in single quotes in queries. Keep in mind this will not return records where the time is not null. For example, this expression selects all records with a value greater than or equal to 1 and less than or equal to 10: This is the equivalent of the following expression: However, the expression with BETWEEN provides better performance if you're querying an indexed field. Step 3: add a time range parameter. The comma cannot be used as a decimal or thousands delimiter in an expression. For example, this expression selects all records with a null value for population: x [NOT] LIKE y [ESCAPE 'escape-character']. If needed, you can use the UCASE and LCASE functions that are equivalent to UPPER or LOWER. You can query numbers using the equal (=), not equal (<>), greater than (>), less than (<), greater than or equal to (>=), less than or equal to (<=), and BETWEEN operators. If integer_exp is negative, numeric_exp is rounded to |integer_exp| places to the left of the decimal point. Scalar subqueries with comparison operators. Returns the base 10 logarithm of float_exp. Returns the smallest integer greater than or equal to numeric_exp. EXTRACT(extract_field FROM extract_source). It can be used with strings (comparison is based on alphabetical order), numbers, and dates. You can query numbers using the equal (=), not equal (<>), greater than (>), less than (<), greater than or equal to (>=), less than or equal to (<=), and BETWEEN operators, for example: Numeric functions can be used to format numbers. When a time that is not null is stored with the dates (for instance, January 12, 1999, 04:00:00), querying the date only will not return the record because when you pass only a date to a date-time field, it will fill the time with zeros and retrieve only the records where the time is 12:00:00 a.m. Returns a string equal to that in string_exp, with all lowercase characters converted to uppercase. Sie können Zeichen und Scripting-Funktionen einfügen und Formatierungs-Tags von ArcGIS in Beschriftungsausdrücken verwenden. See your DBMS documentation for details. It will first try to format the value entered to fit its own format, and then upon saving edits, it will try to tweak the resulting value to fit into the database. For example, this expression selects all the cities in a coverage with names starting with the letters M through Z: String functions can be used to format strings. For example, this query selects all the cities with names starting with the letters M to Z: Selects a record if it has a value greater than or equal to x and less than or equal to y. Because of this, you can enter a time in a shapefile, but you will find that it is dropped when you save your edits. This is fine most of the time, but it also has a few drawbacks: Keep in mind this will not return records where the time is not null. The syntax is as follows: The argument exp can be the name of a column, the result of another scalar function, or a literal. For example, the following expression selects any house with more than 1,500 square feet and a garage for more than two cars: Combines two conditions together and selects a record if at least one condition is true. This makes it easier for developers and applications to query ArcGIS Server services and helps prevent SQL injection attacks. It can be shortened to [Datefield] = #mm-dd-yyyy#. It can be used with strings (comparison is based on alphabetical order), numbers, and dates. Returns a string equal to that in string_exp, with all lowercase characters converted to uppercase. Selektieren (Analyse) Lizenzstufe: Basic Standard Advanced. is always used as the decimal delimiter, regardless of your locale or regional settings. For instance, the ROUND function rounds a number to a given number of decimals in a file geodatabase: Refer to your DBMS documentation for a list of supported numeric functions. A geoanalytics module is also available and allows you to run GeoAnalytics Tools within the script. In this example, the query would return all states starting with the letter A: Refer to the documentation of your DBMS for a list of supported functions. For example, the following expression selects all the houses that have more than 1,500 square feet and a garage for three or more cars: When you use the OR operator, at least one side of the expression of the two separated by the OR operator must be true for the record to be selected, for example: Use the NOT operator at the beginning of an expression to find features or records that don't match the specified expression, for example: NOT expressions can be combined with AND and OR. This can be done with the IN or ANY keyword. It can be used with strings (comparison is based on alphabetical order), numbers, and dates. Greater than or equal to. The validateSQL operation ensures that an SQL-92 expression, such as one written by a user through a user interface, is correct before performing another operation that uses the expression. It can be used with strings (comparison is based on alphabetical order), numbers, and dates. SUBSTRING(string_exp FROM start FOR length). For example, this query would select only the countries that are not also listed in the table indep_countries: This query would return the features with a GDP2006 greater than the GDP2005 of any of the features contained in countries: For each record in the table, a subquery may need to parse all the data in its target table. for one character. Adds, updates, or removes a selection on a layer or table view based on an attribute query. Common queries: searching strings. The following is the full list of functions supported by file geodatabases, shapefiles, coverages, and other file-based data sources. Returns the absolute (positive) value of the specified numeric expression. Offline 10 minutes Start Tutorial Display point, line, and polygon graphics . The purpose of this section is only to help you query against dates, not time values. SQL syntax does not work for calculating fields using Field Calculator. B.: STATE_NAME = 'California' Bei Zeichenfolgen in Ausdrücken muss die Groß … Query expressions in ArcGIS use common SQL syntax. Returns the string_exp with the trim_character removed from the leading, trailing, or both ends of the string. To evaluate all features, use the statement "1=1". This topic describes the elements of common selection queries in ArcGIS. Less than or equal to. Returns the arctangent of float_exp as an angle, expressed in radians. Returns a string equal to that in string_exp, with all uppercase characters converted to lowercase. Arguments denoted as numeric_exp, float_exp, or integer_exp can be the name of a column, the result of another scalar function, or a numeric literal, where the underlying data type could be represented as a numeric type. The main purpose of the ArcMap date format is to store dates, not times. For more information on the CAST function, see CAST and CONVERT. Allgemeine Abfragen: Suchen von Zeichenfolgen . For more information on the CAST function, see CAST and CONVERT. Both of the following statements work: File geodatabases support the use of a time in the date field, so this can be added to the expression: Shapefiles and coverages do not support the use of time in a date field. For example, the following expression selects all states but California: Returns a character string that is the result of concatenating two or more string expressions together. LOG(float_exp) The following table shows a … For instance, the ROUND function would round a number to a given number of decimals in a file geodatabase: Refer to the documentation of your DBMS for a list of supported numeric functions. Dadurch können Entwickler und Anwendungen ArcGIS Server-Services leichter abfragen, und Angriffe durch Einschleusung von SQL-Befehlen werden verhindert. Queries or where clauses are used in ArcGIS to select a subset of records. Now, you can now also use Arcade to calculate new fields directly into your hosted feature layers in ArcGIS Online. Diese Syntax wird beispielsweise mit dem Werkzeug Nach Attributen auswählenoder dem Dialogfeld Abfrage-Managerverwendet, um eine Layer-Definitionsabfragezu erstellen. The syntax is as follows: The argument exp can be the name of a column, the result of another scalar function, or a literal. It can be used with strings (comparison is based on alphabetical order), numbers, and dates. For example, this expression selects all records with a value greater than or equal to 1 and less than or equal to 10: Returns TRUE if the subquery returns at least one record; otherwise, it returns FALSE. Dabei handelt es sich um spezielle Zeichen, mit denen Sie das Aussehen eines Teiles oder der gesamten Beschriftung ändern können. EXTRACT(extract_field FROM extract_source). This can be done by making sure that the query expression involves fields from more than one join table. It can be used with strings (comparison is based on alphabetical order), numbers, and dates. Returns the extract_field portion of the extract_source. Dadurch können Entwickler und Apps gehostete Feature-Layer leichter abfragen und Angriffe durch Einschleusung von SQL-Befehlen verhindert werden. These string functions are 1 based; that is, the first character in the string is character 1. Searching date fields requires careful attention to the syntax required by your data source. For instance, the LEFT function would return a certain number of characters starting on the left of the string. Buffer expressions can be straightforward, such as = Field1 + 10, or much more complicated.. To learn about the Arcade expressions available in ArcGIS Enterprise 10.6 or later, see Buffer expressions.. Since there are many reserved keywords, and new ones can be added in subsequent releases, a good practice is to always enclose a field name with a delimiter. You use an arithmetic operator to add, subtract, multiply, and divide numeric values. String functions can be used to format strings. Less than. This query returns the features with a GDP2006 greater than the GDP2005 of any of the features contained in countries: Subquery support in file geodatabases is limited to the following: The following is the full list of query operators supported by file geodatabases, shapefiles, coverages, and other file-based data sources. For example: The wildcards you use to conduct a partial string search also depend on the data source you are querying. Returns the smallest integer greater than or equal to numeric_exp. For example, you use this syntax using the Select By Attributes tool or with the Query Builder dialog box to set a layer definition query. You must specify the full time stamp when using equal-to queries or no records will be returned. is always used as the decimal delimiter, regardless of your locale or regional settings. UseArcMapExpression: True or False parameter to determine if the reclass expressions should use ArcGIS SQL expression. Subquery support in file geodatabases is limited to the following: The following is the full list of query operators supported by file geodatabases, shapefiles, coverages, and other file-based data sources. For example, this expression searches for four different state names: Selects a record if it has a null value for the specified field. The hh:mm:ss part of the query cannot be omitted even if the time is equal to 00:00:00. Arguments denoted ascharacter_exp are variable-length character strings. Here is an example of a query that will return all records on or after January 1, 2011, for a file geodatabase data source: Dates are stored in the underlying database as a reference to December 30, 1899, at 00:00:00. SQL syntax does not work for calculating fields using the Field Calculator window. For example, to find cities whose 1996 population has not been entered, you can use the following: Alternatively, to find cities whose 1996 population has been entered, you can use the following: The decimal point (.) All SQL used by the file geodatabase is based on the SQL-92 standard. The wildcards you use to query personal geodatabases are asterisk (*) for any number of characters and question mark (?) Use ArcGIS Pro to create a geoprocessing package for use with ArcGIS Runtime. Data_type can be any of the following keywords, which can be specified in uppercase or lowercase: CHAR, VARCHAR, INTEGER, SMALLINT, REAL, DOUBLE, DATE, TIME, DATETIME, NUMERIC, or DECIMAL. ; Expand the Advanced section and enter the table name where the date field belongs. Strings are case sensitive in expressions. ArcGIS-Geoverarbeitungswerkzeug, das einen SELECT-Ausdruck verwendet, um Features aus einer Feature-Class zu extrahieren und in einer neuen Feature-Class auszugeben. If you are not using such a data source, you can force the expression to use this format. Less than or equal to. For example, this expression searches for four different state names: Selects a record if it has a null value for the specified field. This tool works on layers or table views in the ArcMap table of contents, and also on layers or table views created in a scripts using the Make Feature Layer or Make Table View tools. You use comparison operators to compare one expression to another. Returns the remainder of integer_exp1 divided by integer_exp2. Structured Query Language (SQL) is a standard computer language for accessing and managing databases. For file-based data sources such as file geodatabases or shapefiles, you can use the UPPER or LOWER function to set the case for a selection. However, the expression with BETWEEN provides better performance if you're querying an indexed field. Returns the tangent of float_exp, where float_exp is an angle expressed in radians. To specify a field in an SQL expression, provide a delimiter if the field name would otherwise be ambiguous, such as if it were the same as an SQL reserved keyword. File geodatabases provide the limited support for subqueries explained in this section, while enterprise geodatabases provide full support. Data_type can be any of the following keywords, which can be specified in upper- or lowercase: CHAR, VARCHAR, INTEGER, SMALLINT, REAL, DOUBLE, DATE, TIME, DATETIME, NUMERIC, or DECIMAL. In ArcGIS Online müssen Entwickler beim Abfragen gehosteter Feature-Layer standardisierte SQL-Abfragen verwenden. The purpose of this section is only to help you query dates, not time values. If you need to access noncharacter data, use the CAST function. All ArcGIS applications automatically support standard SQL queries. If numeric_exp is greater than zero, 1 is returned. To ensure that every record with FC1.date = date '01/12/2001' is selected, use the following query: This query will select all records with FC1.date = date '01/12/2001', whether or not there was a join match for each particular record. Arguments denoted asstring_exp can be the name of a column, a character-string-literal, or the result of another scalar function, where the underlying data type can be represented as a character type. Greater than. All query expressions use Structured Query Language (SQL) to formulate these search specifications. You use an arithmetic operator to add, subtract, multiply, and divide numeric values. These string functions are 1-based; that is, the first character in the string is character 1. For example, to find the countries with a population density of less than or equal to 25 people per square mile, you can use this expression: Expressions are evaluated according to standard operator precedence rules. The percent symbol (%) means that anything is acceptable in its place: one character, a hundred characters, or no character. See your DBMS documentation for details. The comma cannot be used as a decimal or thousands delimiter in an expression. Please see your DBMS documentation for details. The hh:mm:ss part of the query can be omitted when the time is not set in the records. FilterSQL: The SQL statement used to filter the data layer. The mapping platform for your organization, Free template maps and apps for your industry. Alternatively, if you want to search with a wildcard that represents one character, use an underscore (_). For instance, a time entered as 00:00:15 will show as 12:00:15 a.m. in the attribute table, with the United States as your regional settings, and the comparable query syntax would be Datefield = '1899-12-30 00:00:15'. If you are not using such a data source, you can force the expression to use this format. Strings must always be enclosed in single quotation marks in queries, for example: STATE_NAME = 'California' Strings are case sensitive in expressions. Returns the position of the first character expression in the second character expression. In addition to the functions below, enterprise geodatabases support other capabilities. Querying a date on the left part of a join will be successful when using the limited version of SQL developed for file-based data sources. Returns the sine of float_exp, where float_exp is an angle expressed in radians. File geodatabases support the use of a time in the date field, so this can be added to the expression: Shapefiles and coverages do not support the use of time in a date field. Returns the arcsine of float_exp as an angle, expressed in radians. ; The Spatial filters section allows you to choose which spatial filters will be available to end users. Querying a date on the left part (first table) of a join only works with file-based data sources, such as file geodatabases, shapefiles, and DBF tables. This is fine most of the time but also has a few drawbacks: The hh:mm:ss part of the query cannot be omitted even if it's equal to 00:00:00. If numeric_exp is greater than zero, 1 is returned. For example, this expression selects all the New England states except Maine: Calculations can be included in expressions using the arithmetic operators +, -, *, and /. For example, this expression returns any string containing 10%, such as 10% DISCOUNT or A10%: Combines two conditions and selects a record if both conditions are true. In most ArcGIS dialog boxes where you build a query expression, the name of the layer or table is supplied for you (or you select it from a drop-down list). Subqueries that are performed on versioned ArcSDE feature classes and tables will not return features that are stored in the delta tables. When NULL is preceded by NOT, it selects a record if it has any value for the specified field. For example: Strings are case insensitive for personal geodatabase feature classes and tables. The CAST function converts a value to a specified data type. Returns a character string that is derived from string_exp, beginning at the character position specified by start for length characters. When building SQL expressions for joined layers and tables, the SQL version used depends on the source of the joined data and the query expression. SQL syntax. When publishing a layer from ArcGIS Pro to ArcGIS Online, the date field of the hosted feature layer in ArcGIS Online displays the dates earlier or later than the original dates. For example, if a feature class and a table (FC1 and Table1) are joined and are both from an enterprise geodatabase, the following expressions will fail or return no data: To query successfully, you can create a query as follows: Since the query involves fields from both tables, the limited SQL version will be used. You must specify the full time stamp when using "equal to" queries, or else no records will be returned. If you're querying any file-based data, such as a file geodatabase, ArcSDE geodatabase data, or data in an ArcIMS feature class or image service sublayer, you can enclose field names in double quotes: If you're querying personal geodatabase data, you can enclose fields in square brackets: For personal geodatabase raster datasets, you should enclose field names in double quotes: For File geodatabase data you can enclose your field names in double quotes, but it's generally not needed. The field will then contain a value '1899-12-30' that will show as 12:00:00 a.m. or something equivalent depending on your regional settings. This can be done by making sure the query expression involves fields from more than one join table. To specify a field in an SQL expression, provide a delimiter if the field name would otherwise be ambiguous, such as if it were the same as an SQL reserved keyword. The result is an exact numeric with an implementation-defined precision and a scale of zero. All numeric functions return a numeric value. When preceded by NOT, it selects a record if it has a value outside the specified range. Returns the largest integer less than or equal to numeric_exp. Standardized queries are enforced by default, but can be disabled by the server administrator. If integer_exp is negative, numeric_exp is truncated to |integer_exp| places to the left of the decimal point. For instance, a time entered as 00:00:15 shows as 12:00:15 a.m. in the attribute table, with the United States as your regional settings, and the comparable query syntax is Datefield = '1899-12-30 00:00:15'. This is valid for all the data sources listed here. If numeric_exp is less than zero, -1 is returned. If numeric_exp is less than zero, -1 is returned. There are several tutorials on the internet, but the one I will recommend and use in this article is that on w3schools.So, to keep things simple, I will convert the customers table used on the SQL Tutorial into a shapefile for demonstrations in ArcGIS and QGIS. For example, the part of an expression enclosed in parentheses is evaluated before the part that isn't enclosed. File geodatabases provide the limited support for subqueries explained in this section, while personal and ArcSDE geodatabases provide full support. STATE_NAME = 'Alabama' This would select the features containing "Alabama" in a field named STATE_NAME. When NULL is preceded by NOT, it selects a record if it has any value for the specified field. It is possible to store only a time in the field when the underlying database actually uses a date-time field, but it is not recommended. For example, if a feature class and a table (FC1 and Table1) are joined and are both from a personal geodatabase, the following expressions will fail or return no data: To query successfully, you can create a query as follows: Since the query involves fields from both tables, the limited SQL version will be used. The extract_source argument is a date-time expression. If integer_exp is negative, numeric_exp is rounded to |integer_exp| places to the left of the decimal point. This topic describes the elements of common queries used in selection expressions in ArcGIS. In some cases, the time part of the query may be safely omitted if the field is known to contain only dates; in other cases, it needs to be stated, or the query will return a syntax error. When preceded by NOT, it selects a record if it has a value outside the specified range. It can be used with strings (comparison is based on alphabetical order), numbers, and dates. Arcade expressions offer a flexible way to work with your GIS data on-the-fly. CEILING(numeric_exp) Returns the smallest integer greater than, or equal to, the specified numeric expression. The CAST function converts a value to a specified data type. FLOOR(numeric_exp) Returns the largest integer less than or equal to the specified numeric expression. In some cases, the time part of the query may be safely omitted if the field is known to contain only dates; in other cases, it needs to be stated, or the query will return a syntax error. If you build a date query in Clause mode of the Query Builder, the correct syntax will be automatically generated for you. Building a SQL expression. It may be extremely slow to execute on a large dataset. Alternatively, if you want to search with a wildcard that represents one character, use an underscore (_). For example, the following expression selects all states but California: Returns a character string that is the result of concatenating two or more string expressions. The Create Buffers and Reconstruct Tracks tools can apply buffers based on an expression. Returns the base 10 logarithm of float_exp. You can use the NULL keyword to select features and records that have null values for the specified field. Returns numeric_exp rounded to integer_exp places to the right of the decimal point. You can use them to map your data, label features, configure a popup, and so much more. The decimal point (.) The extract_source argument is a date-time expression. Styling & Visualization 15 minutes Start Tutorial Add, edit, and remove features. Strings must always be enclosed in single quotation marks in queries, for example: Strings are case sensitive in expressions, except when run on geodatabases in Microsoft SQL Server. Returns the cosine of float_exp, where float_exp is an angle expressed in radians. Standardisierte Abfragen werden standardmäßig erzwungen, … The extract_field argument can be one of the following keywords: YEAR, MONTH, DAY, HOUR, MINUTE, or SECOND. Query expressions in ArcGIS use the SQL syntax. For example, this expression selects Mississippi and Missouri among United States state names: The percent symbol (%) means that anything is acceptable in its place: one character, a hundred characters, or no character. For example. In this expression, Table1.OBJECTID is always > 0 for records that matched during join creation, so this expression is true for all rows that contain join matches. ArcGIS Online requires developers to use standardized SQL queries when querying hosted feature layers. An alternative format for querying dates in Oracle follows: The second parameter 'YYYY-MM-DD HH24:MI:SS' describes the format used for querying. Returns the value of numeric_exp to the power of integer_exp. Returns the largest integer less than or equal to numeric_exp. ArcGIS Server bietet eine Sicherheitsoption, die Entwickler dazu zwingt, bei der Arbeit mit Karten-, Feature-, Image- und WFS-Services standardisierte SQL-Abfragen zu verwenden. Returns an indicator of the sign of numeric_exp. Returns numeric_exp truncated to integer_exp places to the right of the decimal point. When the ArcGIS Pro "Select Layer By Attribute" window is first presented, you must select how you want to proceed before you can start building an expression. If numeric_exp equals zero, 0 is returned. Query expressions in ArcGIS use SQL. However, shapefiles do not. Expressions are able to mathematically process numbers. It can be used with strings (comparison is based on alphabetical order), numbers, and dates. They are also supported by enterprise geodatabases, although these data sources may require different syntax. However, there is a possible workaround for working with data that is not file-based, like enterprise data as described below.
