Question

The Bill_Date is saved as a string in the database. Now I want to select the records based on this Bill_Date. So I input two dates ie. fromDate and toDate (which are also in string).

All the date values use the U.S. format mm/dd/yyyy (e.g. 11/28/2011).

So how will be the query?

Answer 1

Firstly, your life will be much easier (and the query much faster) if everything was a datetime.

The query (as it stands) would be:

SELECT *
FROM TABLE
WHERE CONVERT(datetime, BILL_Date, 101)
BETWEEN CONVERT(datetime, @fromDate, 101) AND CONVERT(datetime, @toDate, 101)

CONVERT is detailed here.
