As you type, a prompt appears, showing the field names, values, keywords, and operators supported by your data source. When using ArcGIS dialog boxes to construct a SQL expression, autocomplete helps you apply the correct syntax for the data source you're querying. Databases or enterprise geodatabases use the SQL syntax of the underlying RDBMS, such as, Oracle, SQL Server, PostgreSQL, SAP HANA, and IBM Db2, in which each database uses its own slightly different SQL dialect.

Mobile geodatabases, ST_geometry SQLite, GeoPackage, and Excel use SQLite SQL dialect.xlsx tables, and feature services that use standardized queries use the ArcGIS SQL dialect that supports a subset of SQL capabilities. File-based data, including file geodatabases, shapefiles, in-memory table views, text files such as.Each data source has its own variant of SQL, which are referred to as SQL dialects, such as the following: The SQL syntax you use within an expression differs depending on the data source. Query expressions in ArcGIS adhere to standard SQL expressions. Most RDBMSs use that standard and have extended it, making SQL syntax across different RDBMSs slightly different from one another.

The American National Standards Institute (ANSI) defines a standard for SQL. Managing data in databases and in other data processing Set of defined syntax and expressions used for accessing and Structured Query Language (SQL) is a standard computer language that contains a
