Re: I have two database tables ztable1 and ztable 2 .is it possible to add two fields from different tables and store value into into another field in ztable1.

I try to explain it:

Create a JOIN of the two tables getting all the fields of the table 2, whereby the field total is the combination of the field mark1 from table 1 and the field mark2 from table 2 and store the whole result into an internal table. Update the table 2 by this internal table.
