SQLFLAGGER ( sql-standard-string, sql-statement-string )

• SQL:2003/Core Test for conformance to core SQL/2003 syntax.

• SQL:2003/Package Test for conformance to full SQL/2003 syntax.

• SQL:1999/Core Test for conformance to core SQL/1999 syntax.

The following statement shows an example of the message that is returned when a disallowed extension is found:

SELECT SQLFLAGGER( 'SQL:2003/Package', 'SELECT top 1 dummy_col FROM sys.dummy ORDER BY dummy_col' );

This statement returns the message '0AW03 Disallowed language extension detected in syntax near 'top' on line 1'.

The following statement returns '00000' because it contains no disallowed extensions:

SELECT SQLFLAGGER( 'SQL:2003/Package', 'SELECT dummy_col FROM sys.dummy' );
