Question

I need to search rows entered on a specific date.

However the datatype of column I need to search on is datetime, and the datatype of argument is Date.

I can use the the query like

Select result 
from table 
where
     convert(date, Mycolumn) = @selectedDate

but this would affect the SARGability of the query and will not use indexes created on mycolumn.

I was trying to use the following query:

Select result 
from table 
where  
  Mycolumn 
       BETWEEN @selectedDate AND Dateadd(s, -1, Dateadd(D, 1, @selectedDate)) 

However this does not work since the @selectedDate is Date type and a second can’t be added or removed.

Can someone help me with a working query?

Thanks.

Answer 1

Select result 
from table 
where  
    Mycolumn >= @selectedDate 
AND Mycolumn < Dateadd(D, 1, @selectedDate)
