以不同的名称排序

Question

我的表：

PageOrderID   PageName
3            Citation Number   
3            Citation Number  
3            Citation Number
1            Account Info 
1            Account Info 
1            Account Info

我想根据PageOrderID订购Pagename，但是不同的PageNames。

我尝试了以下但是它无效：

select PageOrderID,distinct(PageName) from ScreenMaster order by PageOrderID

错误是什么？

O / P：

PageOrderID   PageName
1              Account Info
3              Citation Number

Answer 1

select DISTINCT PageOrderID,PageName from ScreenMaster
order by PageOrderID 

Answer 2

也许你想分组：

SELECT PageOrderID,PageName
FROM dbo.ScreenMaster 
GROUP BY PageOrderID,PageName
ORDER BY PageOrderID

Demo

PAGEORDERID     PAGENAME
    1           Account Info
    3           Citation Number

Answer 3

很简单，

select distinct * from ScreenMaster 
order by PageOrderID

Answer 4

试试这个

select DISTINCT PageOrderID,PageName from ScreenMaster group by PageOrderID,PageName order by PageOrderID
