如何将数据从sql server中的一个DB复制到另一个Sql server中的另一个DB？ [英] How to copy data from one DB in sql server to another DB in another Sql server?

问题描述

如何将数据从sql server中的一个DB复制到另一个Sql server中的另一个DB？我正在使用Archival SP实现相同的方法，其中来自Transaction的数据基于存档日期存档，而主表中的数据则不存档。我使用Linked Server在2个sql server实例中的DB之间进行数据传输。我希望SQL Server中的另一个SP脚本除了链接服务器之外还可以执行此操作。



我的档案SP如下：

How to copy data from one DB in sql server to another DB in another Sql server? I am using Archival SP to implement the same where datas from Transaction are archived based on the Archival Date while data in the Master Table isn't . I am using Linked Server for data transfer between the DB in 2 sql server instances. I want another script of SP in SQL Server to do this other than Linked Server.

My Archival SP is as follows:

CREATE   PROCEDURE [dbo].[DIB_ARCHIVE]
(
   @LIVEDB        NVarchar(100)
 , @ARCHIVEDB     Varchar(100)
 , @ArchiveDate    VARCHAR(10)
 , @ArchiveAgeDate VARCHAR(10)
)
AS

DECLARE @TableName Varchar(200)
Declare @DateField Varchar(50)
Declare @TableType char(1)
Declare @STRIDENTITY NVarchar(4000)
Declare @STRINSERT NVarchar(4000)
Declare @STRDELETE NVarchar(4000)
declare @ColumnList varchar(MAX)
declare @STRUSE Nvarchar(100)
declare @DISABLECONSTRAINT Nvarchar(1000) declare @ENABLECONSTRAINT Nvarchar(1000) Declare @Archive_LogID INT Declare @NumRowsChanged INT

SET @DISABLECONSTRAINT=@LIVEDB+'.dbo.sp_MSforeachtable @command1="ALTER TABLE ? NOCHECK CONSTRAINT ALL"'
EXECUTE sp_executesql @DISABLECONSTRAINT SET @DISABLECONSTRAINT=@ARCHIVEDB+'.dbo.sp_MSforeachtable @command1="ALTER TABLE ? NOCHECK CONSTRAINT ALL"'

set @STRUSE='USE '+@LIVEDB

推荐答案

INSERT [NewDB].[your_schema].[tablename](colum1 name,colum2 name)
SELECT colum1name,colum2name
FROM [OldDB].[your_schema].[tablename]

使用SSIS建立连接，然后就可以运行脚本了。你不需要链接服务器在那种情况下......

Use SSIS to establish connection and then you can run your script. You won't need linked server in that case...
