Overriding the Default Query

Overriding the Default Query

You can alter or override the default query in the Source Qualifier transformation by changing the default settings of the transformation properties. Do not change the list of selected ports or the order in which they appear in the query. This list must match the connected transformation output ports.
When you edit transformation properties, the Source Qualifier transformation includes these settings in the default query. However, if you enter an SQL query, the Integration Service uses only the defined SQL statement. The SQL Query overrides the User-Defined Join, Source Filter, Number of Sorted Ports, and Select Distinct settings in the Source Qualifier transformation.
When you override the default SQL query, you must enclose all database reserved words in quotes.
