Building a query for the Production Advanced Query command (Maritime Charting)

An 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 tool.

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

• 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.
