在更改分隔符时，从DROP PROCEDURE语句中删除分号像这样的东西：

delimiter //

DROP PROCEDURE IF EXISTS DIAGNOSIS //  
CREATE PROCEDURE DIAGNOSIS(IN SYM INT, IN DISE VARCHAR(255))      
BEGIN  
 DECLARE I INT DEFAULT 1;  
 DECLARE SYM_COL VARCHAR(50);    
 DECLARE N INT DEFAULT 1;  
 DECLARE C INT DEFAULT 1;  
 DECLARE ST VARCHAR(255);  
 DECLARE DID INT;  
 CREATE TEMPORARY TABLE SYM_TEMP (SID INT, SNAME VARCHAR(50));  
 CREATE TEMPORARY TABLE DISE_TEMP (DID INT, DNAME VARCHAR(100));  
--error stating problem with syntax!!!  
 IF DISE = '' THEN  
  SET SYM_COL = (SELECT SNAME FROM SYMPTOMS WHERE SID = SYM);  
--other set of codes  
 END IF;  
END//  
delimiter ;

我相信其他代码很好
