I am working in MySQL Workbench 6.3 CE and trying to use a trigger inside of a stored procedure to see if it will detect if my email format is not in the right format I specified in the message text error, but I am having trouble because it says a trigger can't be created inside of stored procedure. How else can I accomplish what I need to accomplish. This is a BEFORE TRIGGER since it will check the email validation before any rows are inserted into my Faculty table. What I am I doing wrong? Here is my SQL code below:
-- Create a trigger inside of stored procedure that will enforce that Faculty's Email has to be
-- used in a standard way.
USE College ; DROP PROCEDURE IF EXISTS Faculty_Before_Insert; DELIMITER $$ CREATE PROCEDURE Faculty_Before_Insert() BEGIN CREATE TRIGGER Review_Email_Before BEFORE INSERT ON Faculty FOR EACH ROW BEGIN DECLARE Email varchar(255); IF Email != '^\w+(\.\w+)*+@\w+(\.\w+)+$' THEN SIGNAL SQLSTATE 'HY000' SET MESSAGE_TEXT= 'This email doesn\'t match FirstLast@college.edu'; END IF ; END; END $$ DELIMITER ; INSERT INTO Faculty(LastName, FirstName, Email, HireDate, Salary, DepartmentID) VALUES('Stanley', 'Mike', 'email@example.com', current_date(), 20000, 1); SELECT Faculty.LastName, Faculty.FirstName, Faculty.Email FROM Faculty WHERE ID= last_insert_id();
