And another tool I use a lot.
I often get asked to export all the (relatively small) tables in a schema into worksheets in an excel workbook, one per tab.
Usually, theres a back and forth first with me trying to explain how this probably won’t mean much, the user
not understanding, me explaining, the user either not caring or still not understanding.
Regardless, I end up having to export the data as they ask.
This isn’t a big deal especially using Toad. Unless there’s 100 tables (or, really, 15 is plenty to make it annoying).
This VBA does that all for you.
As before, you’ll have to build a form to bring in the relevant options (like schema, db, password).
I also have it set to do its work based on a naming patterns.
For example, maybe I only want tables that start with EST. If you do or don’t want that, the relevant line is:
“Select table_name from dba_tables where owner = ‘” & inSchema & “‘ and table_name like ‘” & inNameString & “‘ order by table_name”
There is one limitation in that it simply can’t handle any table with a LOB column (regardless as to the data contained within)

Again, I promise nothing as far as HOW this is written, just the functionality.
