openquery跨服务器传输数据

openquery:　　

/*不同服务器数据库之间的数据操作*/

不同数据库之间复制表的数据的方法：

当表目标表存在时：

insert into 目的数据库..表 select * from 源数据库..表  

当目标表不存在时：

select * into 目的数据库..表 from 源数据库..表

当目标存在时，远程向本地插入表数据，如果目标不存在则出错

insert into omdLog select * from OPENQUERY(数据库名,'select * from 数据库名.dbo.表明 where 表字段< ''2008-01-01 00:00:00''') 

当目标不存在时，远程在本地创建表数据，如果目标存在则出错

select * into table_name from 

OPENQUERY(test ,'select * from 数据库名.dbo.表名 where LogDate < ''2009-01-01 00:00:00''') 

insert into 表名 openquery(test,  'SELECT *  FROM 数据库.dbo.表名 ') 

select * from 表名 where 表字段 < @变量

查询：SELECT * FROM OPENQUERY(TEST, 'SELECT * FROM tableName')
写入：INSERT INTO OPENQUERY(TEST, 'SELECT * FROM tableName WHERE 1>1') VALUES(3,6,'ANDY')
更新：UPDATE OPENQUERY(TEST, 'SELECT * FROM tableName') SET role_id = 'ForTest' WHERE id = 3
删除：DELETE OPENQUERY(TEST, 'SELECT * FROM tableName') WHERE id IN (1,3)
