[英]SQL query to run 3 step (Select-Insert-delete) on linked server
I have a linked server to mysql in SQL Server 2008. 我在SQL Server 2008中有一个到mysql的链接服务器。
I'm looking for a stored procedure to do these 3 steps: 我正在寻找一个存储过程来执行这3个步骤:
Before doing with linked server there was a witness machine and that machine this these steps programmatically like this : 在使用链接服务器之前,有一个见证机器和那台机器这些步骤以编程方式如下:
Pseudo code : 伪代码:
SELECT values from source
if($row>0)
{
foreach ($row as $rows)
{
INSERT INTO dest (selected value from source)
Delete from source
}
}
in programmatically way I do a loop and I know exactly when insert happen then I remove the source value, but how can I implement this fail-safe in a stored procedure and a daily job ? 以编程方式我做一个循环,我确切地知道插入发生的时间然后我删除了源值,但是如何在存储过程和日常工作中实现这个故障安全?
This is my insert code method without delete : 这是我的插入代码方法没有删除:
declare @count bigint
select @count = max(id) from dest.table
INSERT INTO dest.table(ID)
SELECT TOP 50000 ID
FROM [sourceLinkedServer].[db].[table]
WHERE ID > @count
Perhaps something like this will do the job: 也许这样的事情可以完成这项工作:
create table #temp (ID int, value varchar(20))
insert into #temp(ID,value)
select top 50000 value from [sourceLinkedServer].[db].[table]
where ID > (select max(ID) from destTable)
order by ID
insert into destTable (value)
select value from #temp
delete ls
from [sourceLinkedServer].[db].[table] as ls
where exists (select 1 from #temp as t where t.id = ls.ID)
drop table #temp
