我试图将数据从一个表插入到另一个表(从表[PPRS]到表[Verify]),其中PPRS中的标题与表[Master]中的标题相同。有人建议我使用循环或数组来插入数据,而不是对其进行硬编码,因此我先尝试了循环
这是我的代码:
Declare @counter int
declare @total int
set @counter = 0
SELECT @total = Count(*) FROM PPRS
while @counter <= @total
begin
set @counter += 1
insert into [Verify]
select [Task_ID],
[Project_StartDate] ,
[PPR_Caption],
[Date]
FROM PPRS
where [PPR_Caption] in (SELECT [Caption] from MasterRecords)
end
无论怎么说(插入0行)
样本数据: Task_ID PPR_Caption Project_StartDate用户 17288 WC-青年环境服务(12/15)30/09/2018 Grace Modubu
答案 0 :(得分:1)
这将插入来自PPRS的所有记录,其中字幕位于MasterRecords中。无需循环
insert into [Verify]
select [Task_ID], [Project_StartDate] , [PPR_Caption], [Date]
FROM PPRS
where [PPR_Caption] in (SELECT [Caption] from MasterRecords);
