Query using combobox

Question

Hai'
I'm working on vb dotnet with sql as backend.
I'm using two forms .
1.to get the employee name and daily dates.
2.form with 2combobox----to display the month(eg.january,april)
To display the name
using table named dept with following fields:
empid varchar(50)
date datetime(8) format:dd/mm/yyyy
empfname varchar(50)
eg:
01/01/2005
04/03/2005
10/01/2005
23/03/2005
19/01/2005
jus want sql query which should compare the date format(dd/[i]mm/yyyy) with the month selected from combobox.
should i assign the string month(april,may) to numeric[b] mm as in the format and then store it in a column.
i'm doing this so that i will be able to retrive the result as a monthly report
eg:
january(selected from combobox)
01/01/2005
10/01/2005
19/01/2005

Answer 1

-- If combo returns numeric month
SELECT *
FROM dept
WHERE MONTH(date) = combo_month
-- If combo returns character month
SELECT *
FROM dept
WHERE MONTH(date) = CASE combo_month WHEN 'January' THEN 1 WHEN 'February' THEN 2 ...... END
Can't remember whether CASE can be used in WHERE clause. If CASE cannot be use in WHERE clause then you just need to write a simple function that can return the month in number when it accepts a character month. Unable to test out the query as I do not have SQL SERVER environment in my current job.
