MySQL在存儲過程中拋出錯誤IF函數

Question

我對我的mysql存儲過程有一些問題，mysql總是顯示錯誤1064，錯誤mysql語法。 我哪里錯了？

   DELIMITER $$

   USE `itin`$$

   DROP PROCEDURE IF EXISTS `sp_Transaction`$$

   CREATE DEFINER=`root`@`localhost` PROCEDURE `sp_Transaction`(IN inpt TINYINT(4), IN inpt2 TINYINT(4))
   BEGIN

   IF((inpt = 0) AND (inpt2 = 0)) THEN  
   SELECT idtr_inventory, showStatus(idms_status) AS idms_status, showLocation(idms_location) AS idms_location
, showUnitType(idms_unittype) AS idms_unittype, USER, user_email
, showDepartment(idms_department) AS idms_department, asset_tag, sn, brand, model, showBBUser(bb_user) AS bbUser
, dt_purchase, warranty, dt_warranty_exp, nm_computer, ip_address, remarks
   FROM tr_inventory;

 ELSE IF(inpt = 0) THEN
 SELECT idtr_inventory, showStatus(idms_status) AS idms_status, showLocation(idms_location) AS idms_location
, showUnitType(idms_unittype) AS idms_unittype, USER, user_email
, showDepartment(idms_department) AS idms_department, asset_tag, sn, brand, model, showBBUser(bb_user) AS bbUser
, dt_purchase, warranty, dt_warranty_exp, nm_computer, ip_address, remarks
 FROM tr_inventory WHERE (idms_location = inpt2);

ELSE IF(inpt2 = 0) THEN
SELECT idtr_inventory, showStatus(idms_status) AS idms_status, showLocation(idms_location) AS idms_location
, showUnitType(idms_unittype) AS idms_unittype, USER, user_email
, showDepartment(idms_department) AS idms_department, asset_tag, sn, brand, model, showBBUser(bb_user) AS bbUser
, dt_purchase, warranty, dt_warranty_exp, nm_computer, ip_address, remarks
FROM tr_inventory WHERE (idms_unittype = inpt)

ELSE 
SELECT idtr_inventory, showStatus(idms_status) AS idms_status, showLocation(idms_location) AS idms_location
, showUnitType(idms_unittype) AS idms_unittype, USER, user_email
, showDepartment(idms_department) AS idms_department, asset_tag, sn, brand, model, showBBUser(bb_user) AS bbUser
, dt_purchase, warranty, dt_warranty_exp, nm_computer, ip_address, remarks
FROM tr_inventory WHERE (idms_unittype = inpt) AND (idms_location = inpt2);

END IF;
END IF;
END IF;

END$$

DELIMITER ;

if語句到底有錯嗎？ 如果是，我需要放在哪里？ 謝謝。

錯誤：查詢：CREATE DEFINER = root @ localhost PROCEDURE sp_Transaction （在inpt tinyint（4），在inpt2 TINYINT（4）中）if（（inpt = 0）AND ...錯誤代碼：1064您的SQL錯誤語法；請查看與您的MySQL服務器版本相對應的手冊，以獲取在'else附近使用的正確語法

你錯過了;

...
FROM tr_inventory WHERE (idms_unittype = inpt);
                                              ^------here
ELSE 
...
