Question

尝试在存储过程中的MySQL临时表中执行3个插入命令，但是select命令只显示执行/插入的第一个插入。

 CREATE TEMPORARY TABLE IF NOT EXISTS OtDates (OtDatesList Date, TotalOTMinutes int);

#Fist Insert
    insert into OtDates(OtDatesList,TotalOTMinutes) values('2017-04-15', 400);
#Second Insert    
    insert into OtDates(OtDatesList,TotalOTMinutes) values(@DateOtHalf, @TotalOTMinutesHalf);
#Third Insert   
    insert into OtDates(OtDatesList,TotalOTMinutes) values(@DateOtFull, @TotalOTMinutesFull);

选择命令仅返回2017-04-15,400，而第二和第三个插入中的变量值未列出。如果我删除第一个插入命令，则第二个插入命令而不是第三个插入命令。

编辑2：

提供完整的存储过程

CREATE DEFINER=`root`@`localhost` PROCEDURE `Test0`()
begin


select @DateOtHalf:=DateofIn, @TotalOTMinutesHalf:=TotalOTMinutes from hrtpunch where TotalOTMinutes >= @ExtraWorkHalfDayInMin and TotalOTMinutes < @ExtraWorkFullDayInMin and EmpID = P_EmpID;

select @DateOtFull:=DateofIn, @TotalOTMinutesFull:=TotalOTMinutes  from hrtpunch where TotalOTMinutes >= @ExtraWorkFullDayInMin and EmpID = P_EmpID;



CREATE TEMPORARY TABLE IF NOT EXISTS OtDates (OtDatesList Date, TotalOTMinutes int);



#Fist Insert
    insert into OtDates(OtDatesList,TotalOTMinutes) values('2017-04-15', 400);
#Second Insert    
    insert into OtDates(OtDatesList,TotalOTMinutes) values(@DateOtHalf, @TotalOTMinutesHalf);
#Third Insert   
    insert into OtDates(OtDatesList,TotalOTMinutes) values(@DateOtFull, @TotalOTMinutesFull);

    select * from OtDates;


 end

编辑3：从“hrtpunch”提供样本数据和表格结构

创建声明

CREATE TABLE `hrtpunch` (
  `ID` int(11) NOT NULL AUTO_INCREMENT,
    `TotalOTMinutes` int(11) DEFAULT NULL,
   PRIMARY KEY (`ID`)
) ENGINE=InnoDB AUTO_INCREMENT=464 DEFAULT CHARSET=utf8;

示例数据插入

insert into hrtpunch (TotalOTMinutes) values(61);
insert into hrtpunch (TotalOTMinutes) values(600);
insert into hrtpunch (TotalOTMinutes) values(301);
insert into hrtpunch (TotalOTMinutes) values(0);

为ExtraWorkHalfDayInMin返回的Int值为160，ExtraWorkFullDayInMin为240

Answer 1

试试这样：

CREATE TEMPORARY TABLE IF NOT EXISTS OtDates (OtDatesList Date, TotalOTMinutes int);

INSERT INTO OtDates (OtDatesList,TotalOTMinutes) VALUES
('2017-04-15', 400), (@DateOtHalf, @TotalOTMinutesHalf), (@DateOtHalf, @TotalOTMinutesHalf)

修改

对于SQL 2005，上面的代码不起作用，所以试试这个：

INSERT INTO OtDates (OtDatesList,TotalOTMinutes) SELECT '2017-04-15', 400 UNION ALL SELECT @DateOtHalf, @TotalOTMinutesHalf UNION ALL SELECT @DateOtHalf, @TotalOTMinutesHalf

Answer 2

解决！

DROP TEMPORARY TABLE IF EXISTS `OtDates`;

CREATE TEMPORARY TABLE IF NOT EXISTS OtDates (OtDatesList Date, TotalOTMinutes int);

    insert into OtDates(OtDatesList,TotalOTMinutes) select @DateOtHalf:=DateofIn, @TotalOTMinutesHalf:=TotalOTMinutes from hrtpunch where TotalOTMinutes >= @ExtraWorkHalfDayInMin and TotalOTMinutes < @ExtraWorkFullDayInMin and EmpID = P_EmpID;



    insert into OtDates(OtDatesList,TotalOTMinutes) select @DateOtFull:=DateofIn, @TotalOTMinutesFull:=TotalOTMinutes  from hrtpunch where TotalOTMinutes >= @ExtraWorkFullDayInMin and EmpID = P_EmpID;
