Hello All,

I am using a query to get data from two tables using UNION All.

How can I add a field to the joined data to show the data from which
table?

Something like For eg.

If I say select field1, field2, field 3 FROM Table1 Union all field1,
field2, field3 FROM Table2

Then can I add a field say field4 (which is not in either table) and
add "A" if the data is from Table1 and "B" if the data from Table2 ?

Thanks
