mysql - 使用mysql存储过程创建并插入临时表

Question

我有一个存储过程如下。

我在这里创建了一个名为tempDesTable 的临时表，并将数据从数据库中放入。现在我必须从另一个选择查询中添加额外的数据。但它显示 Error Code : 1327 Undeclared variable: tempDesTable

BEGIN

    CREATE TEMPORARY TABLE tempDesTable AS (SELECT ID, FirstName, LastName FROM t_users WHERE `DesignationID` = p_DesignationID AND BranchID = 0);      

    SELECT ID, FirstName, LastName INTO `tempDesTable` FROM t_users WHERE `DesignationID` = p_DesignationID AND BranchID = p_BranchID;

END$$

Answer 1

你需要使用 insert ... select 而不是 select ... into

INSERT INTO tempDesTable SELECT ID, FirstName, LastName FROM t_users 
WHERE `DesignationID` = p_DesignationID AND BranchID = p_BranchID;
