How to clear / truncate a table without doing an insert?

I have a job where I want to clear the destination MySQL table at the start of the whole job. I can't use the "Clear table" action-on-table setting on the MySQL output component because the job iterates through a series of inserts, and if I use that then each insert also clears the results of the previous inserts in *this* execution (I am only trying to clear the results of *previous* executions). Please see the attached pic for a clearer explanation.
So basically, how can I easily clear the entire table before I even start?
Any help much appreciated.

Actually don't worry, I figured it out ... you use the tMysqlRow component to just execute arbitrary SQL with a "truncate" statement in it.

Hey, 

 

Actually I wanted to implement a similar case. How does the connection look like?

 

Thanks!

    The action on Table will happen only once per execution and not at individual row.

 

     Lets stick to your other post since we are already interacting there.
