<br>
in a mapserver-project I want to start a query for 2 postggis-layers:
<br>
<br>
select a.id, b.nom from table_a as a, table_b as b where within
(a.the_geom, b.the_geom)=true and nom='test';
<br>
<br>
now I want to delete all datasets from table_a I get as result. How can
I set a delete statement in one sql-query with this selection?
<br>
<br>
Thank you
<br>
