带游标的Mysql存储过程

Mysql光标问题

我已经编写了一个存储过程，它将travel的记录从一个表中插入到2-3个不同的表中 使用insert语句

问题是，我正在检查表1中是否不存在记录，然后按顺序将记录从TENTRABLE插入到表1、表2中 ，但情况有点问题，我不知道它总是进入其他部分

代码示例如下：

CREATE PROCEDURE `insertData`(In clientNo INT,In usedID INT)
BEGIN

declare mame varchar(100);
declare address varchar(100);
declare city varchar(50);
declare IdentityNO1 varchar(20)


declare cur1 cursor for select * from temptable;
declare continue handler for not found set done=1;

SET @clientNo = clientNO;
SET @userID = userID;


    set done = 0;
    open cur1;
    igmLoop: loop
        fetch cur1 into Name,Address,City,IdentityNO1,clientNo;
        if done = 1 then leave igmLoop; end if;

        //If no record exists in some records table1,table2.
        IF ( (SELECT COUNT(*) FROM table1 
               WHERE IndentityNo=IdentityNo1 
                 AND clientNo=@clientNo) < = 0)
              INSERT INTO table1 (Name,IdentityNO) VALUES (name,IdentityNO1);
              INSERT INTO table2 (Address,City) VALUES(address,city);
        ELSE
              INSERT INTO tblexceptional(Name,Address,City,IdentityNo)
              VALUES(name,address,city,IdentityNo1);
    end loop igmLoop;
    close cur1;
END

如果没有THEN或END关键字，则程序无法编译。 检查此链接以了解IF语句的正确语法：

使用EXIST运算符而不是SELECT count*。。。Thanx为您的答案，我将尝试它。但相同的参数名称会导致任何问题吗？因为若我从表中给出相同的参数名和列，我将很好地编译这个过程。@krokodilko，我相信你们的答案需要一个不存在的。。。在条件插入子句中。

IF    EXISTS(  
               SELECT null FROM table1 
               WHERE IndentityNo=IdentityNo1 
                 AND clientNo=@clientNo
      )
THEN
              INSERT INTO table1 (Name,IdentityNO) VALUES (name,IdentityNO1);
              INSERT INTO table2 (Address,City) VALUES(address,city);
ELSE
              INSERT INTO tblexceptional(Name,Address,City,IdentityNo)
              VALUES(name,address,city,IdentityNo1);
END IF;

declare cur1 cursor for 
        select name,Address,City,IdentityNO,clientNo
        from temptable;

CREATE PROCEDURE `insertData`(In p_clientNo INT,In p_usedID INT)

declare cur1 cursor for 
        select name,Address,City,IdentityNO,clientNo
        from temptable;

    set done = 0;
    open cur1;
    igmLoop: loop
        fetch cur1 into v_name,v_Address,v_City,v_IdentityNO,v_clientNo;
        if done = 1 then leave igmLoop; end if;

        //If no record exists in some records table1,table2.
        IF  EXISTS(  SELECT 1 FROM table1 
                     WHERE IndentityNo = v_IdentityNo 
                       AND clientNo = v_clientNo)
              INSERT INTO table1 (Name,IdentityNO) VALUES (v_name,v_IdentityNO);
              INSERT INTO table2 (Address,City) VALUES(v_address,v_city);
        ELSE
              INSERT INTO tblexceptional(Name,Address,City,IdentityNo)
              VALUES(v_name,v_address,v_city,v_IdentityNo);
        END IF;
    end loop igmLoop;
    close cur1;
