I have three fields on one table to confirm there is a match a fourth field. The fourth field can be(condition) the same as an additional field on another table.
Example bpentid+bproleid +prodbrnid = inv (They are on one table.) If bproleid =MB
then bpentid=billing
How can I make a query with this conditions?
