An SQL transformation that runs in script mode drops any incoming transaction boundary from an upstream source or transaction generator. The Integration Service issues a commit after executing the script for each input row in the SQL transformation. The transaction contains the set of rows affected by the script.
An SQL transformation that runs in query mode commits transactions at different points based on the database connection type:
Dynamic database connection
. The Integration Service issues a commit after executing the SQL for each input row. The transaction is the set of rows affected by the script. You cannot use a Transaction Control transformation with dynamic connections in query mode.
The Integration Service issues a commit after processing all the input rows. The transaction includes all the database rows to update. You can override the default behavior by using a Transaction Control transformation to control the transaction, or by using commit and rollback statements in the SQL query.
When you configure an SQL statement to commit or rollback rows, configure the SQL transformation to generate transactions with the Generate Transaction transformation property. Configure the session for user-defined commit.
The following transaction control SQL statements are not valid with the SQL transformation:
