Building a query for the Production Advanced Query Command

A SQL expression can be defined to query features across a database. The results of the query are displayed in the table created with the Production Advanced Query Command.

SQL expressions are built according to a standard syntax, which includes

• Strings must always be enclosed within single quotes. For example:

  COUNTRY = 'United States'

• Expressions are evaluated according to standard operator precedence rules. For example, the part of an expression enclosed in parentheses is evaluated before the part that is not enclosed.
• Wildcards can be used for data in file and enterprise geodatabases.

11. Click Clear to delete a previously created expression and create a new one.
12. Click Load and navigate to the appropriate location if you want to use a previously created query expression WHERE clause.

    注意:

    Clicking Save only saves the WHERE clause but does not save other information such as layer, method, or fields.

15. If you want the field aliases to appear in the query table rather than the field names, check the display field alias name check box.
