sqlserver 连接 oracle的方法：
EXEC sp_addlinkedserver @server = 'gztest', @srvproduct = 'oracle',
@provider = 'msdaora', @datasrc = 'gztest'

EXEC sp_addlinkedsrvlogin 'gztest', false, 'sa', 'gzzb', 'j2eeoracle'

select * from openquery(gztest,'select * from 表名')

exec sp_dropserver 'gztest','droplogins'

SELECT * FROM gztest..GZZB.T_ZJ_JBXX AS T_ZJ_JBXX_1
