Hi everyone,
Can anyone please tell me what is the syntax error in the following code when run in 11g.
FUNCTION plch_func (check_in IN BOOLEAN)
RETURN VARCHAR2
AS
BEGIN
RETURN CASE
WHEN check_in THEN '123'
WHEN TRUE THEN '456'
--WHEN SYSDATE < plch_now () THEN '789'
END ;
END plch_func;
Thanks.

Hi,
Are you getting any errors, cannot see anything wrong (syntactically).
SQL> CREATE OR REPLACE FUNCTION plch_func (check_in IN BOOLEAN)
  2    RETURN VARCHAR2 AS
  3  BEGIN
  4    RETURN CASE
  5             WHEN check_in THEN '123'
  6             WHEN TRUE THEN '456'
  7           --WHEN SYSDATE < plch_now () THEN '789'
  8           END;
  9  END plch_func;
10  /
Function created.
SQL>Regards
