Output type for SQL Insert

Hi,

I've created an SQL query service and added insert statement.

Though the insert statement successfully runs, I get "Unable to Invoke Service TestSQLInsert on MyDBThing : null".

The default Output type is INFOTABLE. Even after changing this output type to Long or anything, I get the same error.

What is the correct output type I should use? Is it right to have INSERT/UPDATE statements in SQL Query service? If not what is the approach I should use for writing INSERT/UPDATE statements.

Regards
