add constraint problem

[aph]

Hi,
I am trying to add constraint, and getting this error.

SQL> alter table ap6.ap_invoices_all
add constraint up_inv_num check(invoice_num = upper invoice_num));


ERROR at line 2:
ORA-02293: cannot enable (AP6.UP_INV_NUM) - check constraint violated

Hintts- The table is already populated. Is this could be the reason?

Thanks in advance.

Does your data meet the constraint requirement? If not you will need to create the constraint with the DISABLE option


ALTER TABLE ap6.ap_invoices_all
ADD CONSTRAINT
up_inv_num CHECK(invoice_num = UPPER(invoice_num)) DISABLE;
