EXEC sp_configure 'Ad Hoc Distributed Queries', 1;--開啟分布式查詢
RECONFIGURE

set IDENTITY_insert TestTable on --設置 某表允許插入遞增量

INSERT INTO TestTable(ID,Date,Info )SELECT a.ID,a.Date,a.Info
FROM OPENROWSET('SQLOLEDB','V';'sa';'123456',
'SELECT * FROM TestDatabase.dbo.TestTable') AS a

set IDENTITY_insert TestTable OFF --設置 不某表允許插入遞增量

EXEC sp_configure 'Ad Hoc Distributed Queries', 0;--關閉分布式查詢

EXEC sp_configure 'show advanced options', 0;--關閉高級配置
