Question

I was trying to get the information from my table Paper_Details based on current date and 15 min before the current time.

and this is my SELECT statement

objcmd.CommandText = "Select * from PAPER_DETAILS where ExamDate = Convert(date, getdate()) and StartTime = (Convert(time, getdate()) - 15)"

But, it is showing this error

Type date is not a defined system type.
Type time is not a defined system type

I’m using SQL Server 2005 and ASP.NET using VB.

I refer the above query from here

Thanks in advance !!

UPDATED

StartTime           |   ExamDate

The sample data of my table, which will help you to understand the scenario.

From, the above sample data, i wanted that, user can view the information respective to that row only on 7/27/2012 from 4:05:00 PM to 4:20:00 PM. I hope, everyone understood my scenario.

Answer 1

this is what, i finally got

objcmd.CommandText = "SELECT * FROM PAPER_DETAILS WHERE ((ExamDate = DATEADD(dd, 0, DATEDIFF(dd, 0, GETDATE()))) AND ((DATEPART(minute, GETDATE()) >= DATEPART(minute, DATEADD(MINUTE, - 15, StartTime)))  AND (DATEPART(hh, GETDATE()) = DATEPART(hh, StartTime)) AND (DATEPART(minute, GETDATE()) <= DATEPART(minute, StartTime))    ))"

And, verified with some sample data, it works fine.!!!
