--设置sql 可以获取实例名称 sp_configure 'xp_cmdshell' , 1; go reconfigure; go
--获取实例名 EXEC sys .xp_cmdshell 'sqlcmd -Lc'
--获取所有数据库 Select * FROM Master..SysDatabases order by Name
--获取数据库所有表 use yeekang ---数据库名称 select * from sysobjects where type = 'U' order by name
--获取指定表字段 select * from syscolumns where id= OBJECT_ID('Userinfo' )
