The number and the order of the output ports must match the number and order of the fields in the query SELECT clause.

The native datatype of an output port in the transformation must match the datatype of the corresponding column in the database. The Integration Service generates a row error when the datatypes do not match.

When the SQL query contains an INSERT, UPDATE, or DELETE clause, the transformation returns data to the SQLError port, the pass-through ports, and the NumRowsAffected port when it is enabled. If you add output ports the ports receive NULL data values.

When the SQL query contains a SELECT statement and the transformation has a pass-through port, the transformation returns data to the pass-through port whether or not the query returns database data. The SQL transformation returns a row with NULL data in the output ports.

You cannot add the "_output" suffix to output port names that you create.

You cannot use the pass-through port to return data from a SELECT query.

When the number of output ports is more than the number of columns in the SELECT clause, the extra ports receive a NULL value.

When the number of output ports is less than the number of columns in the SELECT clause, the Integration Service generates a row error.

You can use string substitution instead of parameter binding in a query. However, the input ports must be string datatypes.
