Question

I have problem with my query on C, I’m using the oci8 driver. This is my query:

SELECT *
FROM employee
WHERE FIRST_NAME like '%BRUCEE%' AND BIRTH_DATE like '28-DEC-72'

In SQLDeveloper I execute the query and it has an output, but while I execute it via CI I get a return null array returned.

FIRSTNAME = VARCHAR2
BIRTH_DATE = DATE (DD-MON-YY)

Can anybody help me with this CI query?

This may be an issue with different tools setting a different NLS_DATE_FORMAT for the session. Try using an ANSI date literal instead to avoid any possible conversion issues:

SELECT *
FROM employee
WHERE FIRST_NAME like '%BRUCEE%'
  AND trunc(BIRTH_DATE) = date '1972-12-28'
