Hello Roland, Do you even need PL/SQL for what you want to do?
rsis> I want to check whether field1 in table1 exists in rsis> table3. If so then I want an insert statement to be rsis> run...insert into table3 If the field *is* in table 3, you want to insert it into table 3 again? I find that an odd requirement. However, you might try something like: INSERT INTO table3 SELECT field1 FROM table1 WHERE field1 IN (SELECT DISTINCT field1 FROM table3); EXISTS might work better than IN. You might need to adjust your SELECT column list to match your target table. I don't know what other columns are in table3. If table3 is really large, I'd consider using EXISTS and getting rid of DISTINCT. Well, you might need to try a few variations to figure out which performs the best.
