tDBOutput (mySQL): truncate and 'Insert or update' keeps table empty

[mr_burns]

Hi,

I have a tDBOutput component which reads data from a tRest component and writes it into a mySQL table:

The property 'Action on Table' of tDBOutput_1 (mytable) is set to 'Default' and 'Action on data' is set to 'Insert or update'.

If I run the job then I can see the data in mySQL table as expected.

Now I want to truncate the mySQL table each time the job is running to get 'fresh' data and consider deleted records in the source table.

Here my problem:

I set the property 'Action on Table' of tDBOutput_1 (mytable) to 'Truncate' and 'Action on data' keep as 'Insert or update'.

If I run the job now the mySQL table is empty.

I expected that 'Action on table' = 'Truncate' truncates the table and 'Action on data' = 'insert or update' inserts the data again.

But as I mentioned the table is empty.

What I am misisng? How to delete/truncate the table each time the job is running ?

Thanks...

Hi

From your screenshot, I see 0 rows are extracted from response string, add a tLogRow before tDBOutput to check if there has data.
