Truncating a table behaves similarly to dropping the table (and needs the drop table privilege). Therefore if there are any foreign keys pointing to it (even if there are no values in the child table) the truncate will fail.

Hello,
Can someone please explain me this:
I tried to truncate a table, it gave ORA-2266. But when I deleted the rows, it did not show the error. And after deleting the rown I tried to truncate the table again, but it still gives ORA-2266

TIA
Prabal

SQL> truncate table supplier_order;
truncate table supplier_order

*

ERROR at line 1:
ORA-02266: unique/primary keys in table referenced by enabled foreign keys

SQL> delete supplier_order;

97 rows deleted.

SQL> truncate table supplier_order;
truncate table supplier_order

*

ERROR at line 1:
ORA-02266: unique/primary keys in table referenced by enabled foreign keys
