SQL 分布式查询、插入递增列示例

复制代码 代码如下:

truncate table TestTable

EXEC sp_configure ‘show advanced options’, 1; — 开启高级配置

RECONFIGURE

EXEC sp_configure ‘Ad Hoc Distributed Queries’, 1;–开启分布式查询

RECONFIGURE

set IDENTITY_insert TestTable on –设置 某表允许插入递增量

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 –设置 不某表允许插入递增量

EXEC sp_configure ‘Ad Hoc Distributed Queries’, 0;–关闭分布式查询

RECONFIGURE

EXEC sp_configure ‘show advanced options’, 0;–关闭高级配置

RECONFIGURE
