Dynamically Creating SQL Statement

I need to create a process to sequentially update a number of tables with the source. I have created a simple table with the table name and last index key which I use to dynamically create a SQL statement (using JS step).

Now that I have this SQL statement all ready, I cannot find a transformation SQL step to take the SQL statement and execute against the DB.

Question: is there a way to inject a prepared SQL statement into a step and have it execute it?

Thank you
