sql语句错误，不能得到随机日期

我为我的sql代码添加newID后，我的日期无法显示，反正可以纠正我的newID（）？首先NEWID（的）是从DBsql语句错误，不能得到随机日期

得到randam数据，我感到我想已经是答案，我将它张贴在明年8小时=）

工作做好

enter code here 
Select [Question],[r1] as [option],[Answer] From ExerciseTable where Question='" + 
((Label)e.Item.FindControl("Label3")).Text + "' AND [r1]!='null' 
UNION 
Select [Question],[r2] as [option],[Answer] From ExerciseTable where Question='" + 
((Label)e.Item.FindControl("Label3")).Text + "' AND [r2]!='null' 
UNION 
Select [Question],[r3] as [option],[Answer] From ExerciseTable where Question='" + 
((Label)e.Item.FindControl("Label3")).Text + "' AND [r3]!='null'

后，我加入NEWID（）它没有工作

Select [Question],[r1] as [option],[Answer] From ExerciseTable where Question='" + 
((Label)e.Item.FindControl("Label3")).Text + "' AND [r1]!='null' order by newID() 
UNION 
Select [Question],[r2] as [option],[Answer] From ExerciseTable where Question='" + 
((Label)e.Item.FindControl("Label3")).Text + "' AND [r2]!='null' order by newID() 
UNION 
Select [Question],[r3] as [option],[Answer] From ExerciseTable where Question='" + 
((Label)e.Item.FindControl("Label3")).Text + "' AND [r3]!='null' order by newID()

什么是'newID（）'？ – V4Vendetta 2012-02-14 04:28:12

首先格式化非常糟糕，其次是SQL INJECTION，第三，只有联合的最后部分需要order by子句。 – 2012-02-14 04:28:30

@ V4Vendetta newID是随机获取sql数据 – 2012-02-14 04:31:36

这是我想要的最新答案。

Select * from (Select [Question],[r1] as [option],[Answer] 
From ExerciseTable where Question='" + ((Label)e.Item.FindControl("Label3")).Text + "' AND [r1]!='null' 
UNION 
Select [Question],[r2] as [option],[Answer] 
From ExerciseTable where Question='" + ((Label)e.Item.FindControl("Label3")).Text + "' AND [r2]!='null' 
UNION 
Select [Question],[r3] as [option],[Answer] 
From ExerciseTable where Question='" + ((Label)e.Item.FindControl("Label3")).Text + "' AND [r3]!='null')t order by Newid()
