I want to compare DateTime
in SQL Server. But I am using Varchar
datatype in Table. So I am using CONVERT
in SQL.
My Query :
Select io.* from tblData as io INNER JOIN tblInterest as ui
ON ui.SubCatId=io.SubCatId
Where ui.UserId=@UserId
AND (CONVERT(DATETIME,io.Start,103 <=CONVERT(DATETIME,@Start,103)
AND CONVERT(DATETIME,io.END,103)>=CONVERT(DATETIME,@End,103))
Now, Issue is that If I am firing query directly then It is showing me data but when It executes in C# then I get black DataTable
.
Query After writing DateTime And UserId which I get from SqlCommand.
Select io.* from tblData as io INNER JOIN tblInterest as ui
ON ui.SubCatId=io.SubCatId
Where ui.UserId=1
AND (CONVERT(DATETIME,io.Start,103)<=CONVERT(DATETIME,'15-04-2014 23:13:30',103)
AND CONVERT(DATETIME,io.END,103)>=CONVERT(DATETIME,'15-04-2014 23:13:30',103))
What can be the issue ?

Right here is the error. STOP THAT. You can not do that efficiently, it is a typical beginner mistake and you better stop that at the root cause, which is a non-standard way of handling datetime. Then suddenly everything else turns out to be super easy.
