Question

I have a database with date format “yyyyymmdd’ and data-type varchar(8). In this case when I need to find a data for whole month I used to write code like below :

  select * from table1
  where Date Between (convert(varchar(6),getdate(),112)+'01')
  AND (convert(varchar(6),getdate(),112)+'31'))

Now I just have a new table with date format “dd/mm/yyyy” and date type varchar(10) and I would like to extract data from the table for whole month without specifying exact date. I want start date as first day of current and month and end date as last day of the current month.

But I don’t now how to do the same as the date format is now ‘dd/mm/yyyy’.

Answer 1

First, thing you should store you date as the datatype of date and not varchar

You can use MONTH()

SELECT *
FROM yourTable
WHERE MONTH(convert(datetime, dt, 103)) = MONTH(getdate()) -- or month you want

or DATEPART()

SELECT *
FROM yourTable
WHERE DatePart(month, convert(datetime, dt, 103)) = DatePart(month, getdate())

See SQL Fiddle with Demo

Both of these, get the value of the MONTH() — 8, 9, 10 — and then compares it to the month that you want.
