ORA-06502: PL/SQL: numeric or value error ORA-06512: at "SYS.OWA_UTIL"

Question

Was working on tutorial from the:
Oracle Database Express Edition 2 Day Plus Application Express Developer Guide
Working on the section 4: How to Control Form Layout.
Ran into a problem trying to compile the Create HT-EMP Table script.
keep getting this error for this particular segment creating the bu_ht_emp trigger:
pp. 4-2 and 4-3
CREATE OR REPLACE TRIGGER bi_ht_emp
BEFORE INSERT ON ht_emp
FOR EACH ROW
BEGIN
SELECT ht_emp_seq.nextval
INTO :new.emp_id
FROM DUAL;
:new.rec_create_date := SYSDATE;
END;
ORA-06502: PL/SQL: numeric or value error ORA-06512: at "SYS.OWA_UTIL", line 354....etc
I've check the syntax for the entire script and it all checks out. Does anyone have a clue why this is failing?

Answer 1

If I'm looking at the same DDL, not seeing where it would throw an owa_util error, are you running it in the apex script editor?
Just plain sqlplus doesn't like the empty line stuck in with the list of check constraints on the emp_dept column, after fixing that up (and dropping the sequence that got created on the first pass) the DDL and insert runs fine-
