You call a non-existent procedure to raise the error, and then declare an exit handler that catches the error you generated. Here's an example, using SQLSTATE 42000 (procedure does not exist) to throw an error before deletion if the row to be deleted has a foreign key id set: DROP PROCEDURE IF EXISTS decount_test; DELIMITER // CREATE DEFINER = 'root'@'localh

this tutorial, you will learn how to use SIGNAL and RESIGNAL statements to raise error conditions inside stored procedures.MySQL SIGNAL statementYou use the http://www.mysqltutorial.org/mysql-signal-resignal/ SIGNAL statement to return an error or warning condition to the caller from a stored program e.g., stored procedure, stored function, trigger or event. The SIGNAL statement provides you with control over which information for returning such as value and messageSQLSTATE.The following illustrates syntax of the SIGNAL statement: SIGNAL SQLSTATE stored procedure | condition_name; SET condition_information_item_name_1 = value_1, condition_information_item_name_1 = value_2, etc;123SIGNAL SQLSTATE | condition_name;SET condition_information_item_name_1 = value_1,condition_information_item_name_1 = value_2, etc;Following the SIGNAL keyword is a SQLSTATE value or a condition name declared by the DECLARE CONDITION statement. Notice that the SIGNAL statement must always specify a SQLSTATE value or a named condition that mysql stored procedure defined with an SQLSTATE value.To provide the caller with information, you use the SET clause. If you want to return multiple condition information item names with values, you need to separate each name/value pair by a comma.The condition_information_item_name can be MESSAGE_TEXT, MYSQL_ERRORNO, CURSOR_NAME , etc.The following stored procedure adds an order line item into an existing sales order. It issues an error message if the order number does not exist. DELIMITER $$ CREATE PROCEDURE AddOrderItem( in orderNo int, in productCode varchar(45), in qty int, in price double, in lineNo int ) BEGIN DECLARE C INT; SELECT COUNT(orderNumber) INTO C FROM orders WHERE orderNumber = orderNo; -- check if orderNumber exists IF(C != 1) THEN SIGNAL SQLSTATE '45000' SET MESSAGE_TEXT = 'Order No not found in orders table'; END IF; -- more code below -- ...
