Example

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 does not contain any disallowed extensions: 

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