This works,too. Thank you very much. What's the difference between ( IN
tablename text)
and ( tablename text).
---------- one more questions thanks.
After I created the function sucessfully , I want to execute the function. I
get errors as follows :
rrp=> select truncate_t(t1);
ERROR: column "t1" does not exist
LINE 1 : select truncate_t(t1);
^
rrp=> select truncate_t(rrp.t1);
ERROR:missing FROM-clause entry for table "rrp"
LINE 1 : select truncate_t(rrp.t1);
^
