Обсуждение: how to emulate a simple case of a view on unions

I have four tables with identical fields and I would like
to automate the same query on each table and pool the
results.

Any suggestions on streamlining this?

Thanks!

You could try combining it into one query spanning the four tables:
select tab1.field, tab2.field, tab3.file, tab4.field from
tab1,tab2,tab3,tab4 WHERE clause..;
