Question

how to check whether the sql has executed without errors
exception is one thing
is there any other way or means for this
if so, can any one help in this regard

Answer 1

For Checking the SQL error you can trap the error number and error message and log into any table by following way
CREATE OR REPLACE PROCEDURE FOR_ERROR_LOG as
v_err_num NUMBER (20) := 0;
v_err_msg VARCHAR2 (100) := NULL;
BEGIN
SQL statements like select, insert, update.
EXCEPTION
WHEN OTHERS THEN
v_err_num := SQLCODE;
v_err_msg := SUBSTR (SQLERRM, 1, 100);
INSERT INTO error_table VALUES ('FOR_ERROR_LOG',NULL, v_err_num, v_err_msg, SYSDATE);
COMMIT;
END ;
