在SQL Server中按日期排序

Question

I want to sort a table by date in ascending order. The table also contains null values.

I want to display data in Gridview. I want to display the data like first all rows which contains date field and then date as blank field.

I used below query :

select * from TempTable order by convert(datetime, Date,101) asc

Please help me.

Thanks in Advance.

Answer 1

Then you should check for null values:

Select * FROM TempTable 
ORDER BY CASE WHEN datetime IS NULL THEN 1 ELSE 0 END ASC 
,  Date ASC

Answer 2

select * from TempTable 
order by case when [Date] is null then 1 else 0 end, [Date]
