to handle exceptions or errors encountered in stored procedures.When an error occurs inside a stored procedure, it is important to handle it appropriately, such as continuing or exiting the current code block’s execution, and issuing a meaningful error message.MySQL provides an easy way to define handlers that handle from general conditions such as warnings or exceptions to specific conditions e.g., specific error codes.Declaring a handlerTo declare a handler, you use the DECLARE HANDLER statement as follows: DECLARE action HANDLER FOR condition_value statement;1DECLARE action HANDLER FOR condition_value statement;If a condition whose value matches the condition_value , MySQL will execute the statement and continue or exit the current code block based on the action . The action accepts one of the following values:CONTINUE : the execution of the enclosing code block ( BEGIN … END ) continues.EXIT : the execution of the enclosing code block, where the handler is declared, terminates.The condition_value specifies a particular condition or a class of conditions that activates the handler. The condition_value accepts one of the following values:A MySQL error code.A standard SQLSTATE value. Or it can be an SQLWARNING , NOTFOUND or SQLEXCEPTION condition, which is shorthand for the class of SQLSTATE values. The NOTFOUND condition is used for a cursor or SELECT INTO variable_list statement.A named condition associated with either a MySQL error code or SQLSTATE value.The statement could be a simple statement or a compound statement enclosing by the BEGIN and END keywords.MySQL error handling examplesLet’s look into several examples of declaring handlers.The following handler means that if an error occurs, set the value of the has_error variable to 1 and continue the execution. DECLARE CONTINUE HANDLER FOR SQLEXCEPTION SET has_error = 1;1DECLARE CONTINUE HANDLER FOR SQLEXCEPTION SET has_error = 1;The following is another handler which means that in case any error occurs, rollback the previous operation, issue an error message, and exit the current code block. If you declare it inside the BEGIN END block of a stored procedure, it will terminate stor
