Teoh Teik Liang ([EMAIL PROTECTED]) reports a bug with a severity of 3 The lower the number the more severe it is. Short Description serial data type problem Long Description I had created a table with 2 fields (transaction_code serial primary key) and (trans_desc varchar(20) not null). I found that when I insert a null value into a trans_desc field, the record is not added because of the field is not able to key in null value. But the transaction_code already increase 1 for me. So, if I add the another record, the transaction_code will skip 1 value. How can I make the transaction_code not to increase if the record is not added into the table? Sample Code CREATE TABLE TEST ( TRANSACTION_CODE SERIAL PRIMARY KEY, TRANS_DESC VARCHAR(20) NOT NULL, PARTICULAR VARCHAR(30) NOT NULL ); INSERT INTO TEST (PARTICULAR) VALUES ('TEST2'); *** CANNOT ADD RECORD BUT TRANSACTION_CODE INCREASED ALREADY. *** INSERT INTO TEST (TRANS_DESC, PARTICULAR) VALUES ('TEST2', 'TEST PAR'); *** TRANSACTION_CODE WILL START FROM 2 *** No file was uploaded with this report ---------------------------(end of broadcast)--------------------------- TIP 2: you can get off all lists at once with the unregister command (send "unregister YourEmailAddressHere" to [EMAIL PROTECTED])
