我找到了一种方法,使用此模板使来自不同数据库的两个表相互匹配:
INSERT [DestDB].[dbo].[TABLE]
SELECT source.* FROM
[SourceDB].[dbo].[TABLE] AS source
LEFT OUTER JOIN
[DestDB].[dbo].[TABLE] AS dest
ON
source.[PKColumn] = dest.[PKColumn]
WHERE dest.[PKcolumn] IS NULL
UPDATE dest
SET
dest.[PK_COLUMN1] = source.[PK_COLUMN1]
,dest.[COLUMN2] = source.[COLUMN2]
,dest.[COLUMN3] = source.[COLUMN3]
,dest.[COLUMN4] = source.[COLUMN4]
,dest.[COLUMN5] = source.[COLUMN5]
,dest.[COLUMN6] = source.[COLUMN6]
,dest.[COLUMN7] = source.[COLUMN7]
,dest.[COLUMN8] = source.[COLUMN8]
FROM
[SourceDB].[dbo].[TABLE] AS source
INNER JOIN
[DestDB].[dbo].[TABLE] AS dest
ON source.[PK_Column1] = dest.[PK_Column1]
然而,我正在使用的一些表至少有200列,虽然可以通过复制+粘贴的功能来实现这一点,但我只需要知道是否有一种方法不会让我得到Carpel Tunnel Syndrome.
我正在使用Microsoft SQL Server 2005.
有什么建议？
