SQL SERVER 查看用户权限
--用户与角色关系
select a.uid as uid,a.status as uStatus,a.name as uName,
b.uid as rId,b.status as rStatus,b.name as rName

where a.issqlrole = 0 and a.isapprole = 0 and a.hasdbaccess = 1 and (b.issqlrole = 1 or b.isapprole = 1)
--用户在数据库中的授权信息
select b.id,b.name as tName,b.type,a.uid,c.name as uName,a.action,a.protecttype,a.columns
from sysprotects a inner join sysobjects b on a.id = b.id
inner join sysusers c on a.uid = c.uid

select CONVERT(varchar, getdate(), 120 )

select replace(replac ......
