I have two tables. First with points, and second with polygons. I need to find out which points are in required polygon according to the attribute gid.

Using query: SELECT table1.* FROM table1, table2 WHERE table2.gid=1 AND ST_Contains(table2.geom2, table1.geom1);

What I get is empty table (only columns without data)...

Tnx
