1.You can define error message for predefined oracle error number.. But once you declare pragma statement, exception are handled implicitly... No need to raise exception explicitly... 2.User could define error message for predefined ora- error number. I guess this would be advantage of using it.. 3.The pragma actually makes it possible to check for errors which are not predefined. the only other way would be to check with 'WHEN OTHERS' clause and then accessing the oracle error code. 4.To enhance application interface and display accurate reason for an error.

This is sample of query for  SQL insert query validation constraints to limit number of records lets you want to insert only 1000 records in table . We can restrict number of rows, but need to add a column on which we can add some constraint ... check below example.! CREATE TABLE TAB_1000_ROWS AS SELECT ROWNUM COL1 FROM DUAL CONNECT BY ROWNUM <1001; ALTER TABLE TAB_1000_ROWS ADD CONSTRAINT CHECK_CONST CHECK (COL1 BETWEEN 1 AND 1000); ALTER TABLE TAB_1000_ROWS MODIFY COL1 NUMBER NOT NULL; ALTER TABLE TAB_1000_ROWS ADD CONSTRAINT UNIQUE_COL1 UNIQUE (COL1); -- or we can also use sequence with max as 100 and no-cycle! after insertion of 100 values it wont allow any new values to get inserted! will throw check or unique constraint!
