Hello Raul77,

if you dont want to put the year, use to differernt columns to store the Month and day, you can query the upcoming birth days by using

SELECT *
FROM urTable
WHERE MONTH (Getdate() ) = dobMonth

Hello Aneesh
thanks for the help ,
so i need to create 2 col. in DB , should they be type datetime?

btw i am using MSSQL 2000.

and in case you are wondering this is how i populate my dropdownlist

 DateTimeFormatInfo dtfi = new DateTimeFormatInfo();
        for (int month = 1; month < 13; month++)
        {
            ListItem li = new ListItem();
            li.Text = dtfi.GetMonthName(month);
            li.Value = month.ToString();
            ddlMonth.Items.Add(li);
        }
        for (int i = 1; i < 32; i++)
        {
            ListItem day = new ListItem();
            day.Text = i.ToString();
            day.Value = i.ToString();
            ddlDay.Items.Add(day);
        }

DECLARE @Day tinyint,
@Month tinyint
-- for current month
SELECT NAme, dob_Day, dob_Month
FROM urDOBTable
WHERE dob_day > @day and dob_month = @month
UNION ALL
SELECT NAme, dob_Day, dob_Month --- nextMonth
FROM urDOBTable
WHERE dob_month = CASE WHEN @month =12 THEN 1 ELSE @month END

thanks Aneesh,
we are almost there, since i need the next 2 months i modified your script abit however now i am getting 2 table, we need to union ALL selects in 1 table

Thanks,

SELECT username, Bday, Bmonth
FROM users
WHERE Bday > 14 and Bmonth = 5
UNION ALL
SELECT username, Bday, Bmonth --- nextMonth
FROM users
WHERE Bmonth = CASE WHEN 5 =12 THEN 1 ELSE 6 END

SELECT username, Bday, Bmonth
FROM users
WHERE Bday < 14 and Bmonth = 7

SELECT username, Bday, Bmonth
FROM users
WHERE Bday > 14 and Bmonth = 5
UNION ALL
SELECT username, Bday, Bmonth --- nextMonth
FROM users
WHERE Bmonth = CASE WHEN 5 =12 THEN 1 ELSE 6 END
 
SELECT username, Bday, Bmonth
FROM users
WHERE Bday < 14 and Bmonth = 7
