essentialy you want all the records for Mar 26th?
1. If you don't need time only store the date portion of GetDate(). Probably not an option.
select convert(varchar,getdate(),101)
2. Remove the time component in your date attribute in your search. This approach will probably cause a table scan.
WHERE convert(varchar,date,101)='3/26/2003'
3. Use the between test. Some times can be extra work.
WHERE date between '3/26/2003' and '3/26/2003 23:59:59'
