MYSQL cursor loop, runs one extra round, why?

Question

I\'m looping through a cursor result set in a MYSQL stored procedure. I\'m facing an issue which is that the loop always run thorough the last record twice. Here is my code,

Answer 1

YOU MUST CORRECT TYPE BECAUSE I WRITE DEFAULT (i dont know what You have in table credit). End If U create table TempTable use

TRUNCATE TempTable;

Please rewrite example

CREATE CREATE TEMPORARY TABLE TempTable (`Id` int(11) NOT NULL auto_increment,
  `customer_id` int(11) NOT NULL,
  `amount` int(11) NOT NULL,
  `status` varchar(1000) NOT NULL,
  `user_type` int(11) NOT NULL default '0',
  `employee` varchar(1000) NOT NULL,
  PRIMARY KEY  (`customer_id`),
) ENGINE=InnoDB DEFAULT CHARSET=utf8 COLLATE=utf8_polish_ci AUTO_INCREMENT=1 ;");

ofcourse type is bad :)

 DELIMITER $$
    DROP PROCEDURE IF EXISTS CursorX $$
    CREATE PROCEDURE `CursorX`()
    BEGIN    
            DECLARE xCustomerId int(11);  
            DECLARE xStatus   int(11);
            DECLARE xUserType  varchar(255);
            DECLARE xEmployee  varchar(255);
            DECLARE xNote varchar(255);  
            DECLARE i int(11);
            DECLARE recordNotFound INTEGER DEFAULT 0;
            DECLARE cur_credit CURSOR FOR SELECT customer_id, amount, status, user_type, employee, note FROM credit WHERE status = 'approved' AND customer_id = int_cust_id;
            DECLARE CONTINUE HANDLER FOR NOT FOUND SET recordNotFound = 1;

            DROP TEMPORARY TABLE IF EXISTS TempTable;
            CREATE TEMPORARY TABLE TempTable AS(SELECT * FROM credit);

            OPEN cur_credit;
            set not_found_creadit = 0;
            credit_loop: LOOP
            SET i = i +1;
                FETCH cur_credit INTO xCustomerId,xStatus,xUserType,xEmployee,xNote;
                IF not_found_creadit THEN
                    LEAVE credit_loop;
                 END IF;
            END LOOP credit_loop;
            CLOSE cur_credit;
    select * FROM TempTable;

    END $$
