三张表:
用户表,角色表,用户角色关系表
三表连接分页sql语句,用户和角色是一对多的关系,一个用户可以有多个角色。
我的代码如下:
select count(*) from dbo.Users a,dbo.Role b,dbo.UserRole c where a.Uid=c.Uid and b.RoleId=c.RoleId and del=1;select top " + pagesize + " * from (select a.*,b.RoleName from dbo.Users a,dbo.Role b,dbo.UserRole c where a.Uid=c.Uid and b.RoleId=c.RoleId and del=1)a where Uid not in(select top " + ((pageindex - 1) * pagesize) + " Uid from(select a.*,b.RoleName from dbo.Users a,dbo.Role b,dbo.UserRole c where a.Uid=c.Uid and b.RoleId=c.RoleId and del=1)a order by Uid desc) order by Uid desc";按角色显示,当显示所有角色时就有重复的用户,这些重复用户又是以不同的角色存在的。
请教各位高手!
