I am having problem there. see what happens
sqlstr := 'insert into test(c1, c2) values ('||COALESCE(rec.c1,'NULL')||','
||'\''||rec.c2||'\')';
WARNING: Error occurred while executing PL/pgSQL function test_fn
WARNING: line 8 at assignment
ERROR: pg_atoi: error in "NULL": can't parse "NULL"
Dont forgot that c1 is int.
when i have like this
sqlstr := 'insert into test(c1, c2) values ('||COALESCE(rec.c1,NULL)||','
||'\''||rec.c2||'\')';
NOTICE: <NULL>
WARNING: Error occurred while executing PL/pgSQL function test_fn
WARNING: line 11 at execute statement
ERROR: cannot EXECUTE NULL query
That is the problem i am facing. Please shed some light.
Thanks
Kumar
