In MySql Stored Procedure updating more than one time
- by Both FM
In MySql
UPDATE `inventoryentry` SET `Status` = 1 WHERE `InventoryID`=92 AND `ItemID`=28;
It successfully update only one row , where inventoryID = 92 and itemID=28 , the following message displayed.
1 row(s) affected
when I put this on stored procedure, as follow
CREATE DEFINER=`root`@`localhost` PROCEDURE `Sample`(IN itemId INT, IN itemQnty
DOUBLE, IN invID INT)
BEGIN
DECLARE crntQnty DOUBLE;
DECLARE nwQnty DOUBLE;
SET crntQnty=(SELECT `QuantityOnHand` FROM `item` WHERE id=itemId);
SET nwQnty=itemQnty+crntQnty;
UPDATE `item` SET `QuantityOnHand`=nwQnty WHERE `Id`=itemId;
UPDATE `inventoryentry` SET `Status` = 1 WHERE `InventoryID`=invID AND
`ItemID`=itemId;
END$$
calling stored procedures
CALL Sample(28,10,92)
It update all the status = 1 in inventoryentry against InventoryID (i.e. 92) ignoring ItemID, instead of updating only one row. The following message displayed!
5 row(s) affected
Why Stored procedure ignoring itemID in update statement ? or Why Stored procedure updating more than one time? But without Stored procedure it working fine.
