Oracle SQL statement error - ORA-00905: missing keyword

Question

Can someone please help me with the following Oracle SQL Statement. I am getting an error:

ORA-00905: missing keyword

ALTER TABLE loan_transaction_codes 
 ADD FOREIGN KEY (non_accrual_debit_code) 
   REFERENCES dbo.general_ledger_accounts (gl_account_no) 
   ON UPDATE NO ACTION 
   ON DELETE NO ACTION

Answer 1

Oracle Database does not have an ON UPDATE clause in referential constraint syntax, it only has an ON DELETE (optional) clause; and the only options for ON DELETE are CASCADE and SET NULL , there is no NO ACTION option. Please refer to the Oracle documentation, which is very easy to find and read.
