Date Diffrence in SQL

Diffrence Between Dates In SQL

We use  convert(varchar, getdate(), 101) format to save data.which will save record in format mm/dd/yyyy  so that we can work on dates easily

On Insertion

Insert into tbSample values ('anycontent',convert(varchar, @OnDate, 101))

On Execution Time

SELECT    * from tbSample where OnDate between convert(varchar, '5/9/2012', 101) and convert(varchar, '5/11/2012', 101)";

Other DateTime Formats Are Below

SELECT convert(varchar, getdate(), 100) -- mon dd yyyy hh:mmAM (or PM)

                                        -- Oct  2 2008 11:01AM
