Answer 1

Please, have a look a CAST and CONVERT for more information.

Here are some examples:

-- converting from DD-MM-YYYY
select CONVERT(datetime, '29/11/2013 12:00:00 AM', 103)

-- converting from MM-DD-YYYY
select CONVERT(datetime, '11/29/2013 12:00:00 AM', 101)

IF Your date is of type varchar in the database then if you need to retrieve then these cases arises:: case1:if your data is in the format of "dd-MM-yyyy" then you need to use query as follows Query:: select * from [yourTableName] where convert(datetime,YourDateColumn,103) between '2016-02-12'(yyyy-MM-dd) AND '2016-03-12'

case2:if your data is in the format of "dd-MM-yyyy HH:mm:ss"

then you need to use query as follows Query:: select * from [yourTableName] where convert(datetime,YourDateColumn,105) between '2016-02-12'(yyyy-MM-dd) AND '2016-03-12'
