Whenever I execute TRIM(' ')in a stored procedure or trigger, I get an
ORA-03113 error.
I have an oracle db 8.1.7.0.1 Enterprise edition installed on a
linux-Mandrake 9.1.
EXEMPLE:
I created the function IS_NULL which returns 1 or 0 if the parameter is
empty or not:
CREATE OR REPLACE FUNCTION IS_NULL(v VARCHAR2)
RETURN NUMBER
IS
BEGIN
IF TRIM(v) IS NULL THEN
RETURN 1;
ELSE
RETURN 1;
END IF;
END;
When excuting the following sql I get an ORA-03113 error
SQL> select is_null(' ') from dual;
select is_null(' ') from dual
*
ERROR at line 1:
ORA-03113: end-of-file on communication channel
What's wrong with TRIM(' ') and how else can I check if a variable
consists of empty spaces without using TRIM?
