Hi all,

   Good Day!  I am using SQL SERVER 2008 and Microsoft Visual Studio 2008.  In the i have a database table which contains a column for data and time as string. in that column i have both date and time. In my application i have to select date and based on that date i have to get the data from table and show in data grid view control. So i want to compare only with date. 

And i referred the below link. But it is not working for me.
