Question

I’ve tried to compare a date passed as parameter to a stored procedure from asp.net with a date in database. But cannot yield the needed result..

My query is as follows:

         @date datetime

         Select * from table
         where (CONVERT(NVARCHAR,[date],112)=CONVERT(NVARCHAR,@date,112))

I’ve no issue to insert a date passed as a parameter from asp.net, the sql server takes care of the date format..

Any one please tell me how i can compare those dates..

Answer 1

The correct way to do this is

@date datetime

Select * from table          
where [date] = @date

edit: if you just want to compare the date component (excluding time) in SQL2005, compare the year, month and day.

Select * from table          
where DATEPART(YEAR, [date]) = DATEPART(YEAR, @date)
and DATEPART(MONTH, [date]) = DATEPART(MONTH, @date)
and DATEPART(DAY, [date]) = DATEPART(DAY, @date)

I always prefer avoiding string comparisons.
