Hi
My database has a new column but i can not see it in my data module connection .
Do I need to update something?
I'm assuming that you mean, you don't see it in the module tree. Do you see it in the sources tree?
If you can, you add the new columns to the module by dragging and dropping them. You will get them added to the query subjects at the end of the query item lists, which will be out of order from how they appear in the source but you can move them around and having them at the end of the list makes it easier to confirm that they are now added.
