PSEUDO COLUMNS, INSERT, SELECT, UPDATE

Description

A Pseudo Column behaves like a table column, but is not actually stored in the table. You can select from Pseudo Columns, but they cannot be updated. Pseudo Columns provide extra information about a SELECT row set.

The CURRVAL Pseudo Column will return the current sequence number from the specified table. Sequence numbers can be used for primary and unique index keys.

Example

CREATE TABLE cust (acc_num INT , acc_name char(20))
INSERT INTO cust (acc_num, acc_name) VALUES (NEXTVAL, "Smith")
INSERT INTO cust (acc_name) VALUES ("Brown")
INSERT INTO cust (acc_num, acc_name) VALUES (CURRVAL+2, "Jones")
SELECT * from cust
