Question

I am trying to check for people in a certain age range. I have two ComboBoxes, minagecombobox and maxagecombobox, with values between 1 and 120.

I want to get the people whose age is between these two values (suppose for example I want to filter out the people aged between 18 and 24).

This is the Member table structure:

     member_id 
     member_firstname 
     member_dob(datatype is string) (values like 1987-09-08,1976-09-08,.....)

i am using mysql as my database…..

**Modified query** 


             SELECT members.member_Id,
                   members.member_Lastname as 'Last Name',
                   members.member_Firstname as 'First Name',
                   members.member_Postcode as 'Post Code',
                   members.member_Reference as Reference,
                   members.member_CardNum as 'Card Number',
                   members.member_IsBiometric as Biometric,
                   members.member_DOB as DoB,
                   mshiptypes.mshipType_Name as Membership,
                   mshipstatustypes.mshipStatusType_Name as Status,
                   membertomships.memberToMship_EndDate as Expiry
                     FROM members
    INNER JOIN membertomships ON membertomships.member_Id = members.member_Id
     INNER JOIN mshipoptions ON mshipoptions.mshipOption_Id = membertomships.mshipOption_Id
    INNER JOIN mshiptypes ON mshiptypes.mshipType_Id = mshipoptions.mshipType_Id
    INNER JOIN mshipstatustypes ON mshipStatusTypes.mshipStatusType_Id = membertomships.mshipStatusType_Id
    WHERE memberToMship_EndDate BETWEEN '2011-09-24' AND '2011-09-30'
    AND members.member_active LIKE 'y%'
    AND (YEAR(CURDATE(members.member_Dob))-YEAR()) - (RIGHT(CURDATE(),5)< RIGHT(member_Dob,5)) BETWEEN '21' AND '102'
    ORDER BY members.member_Lastname

got an error like this…..

     Error Code: 1064

Answer 1

Try this:

SELECT * FROM MEMBER
WHERE (YEAR(CURDATE())-YEAR(member_dob)) - (RIGHT(CURDATE(),5)<RIGHT(member_dob,5)) 
BETWEEN 18 AND 24

The WHERE clause has the age calculation formula. Get the number of years by subtracting the year of birth from current year and then further subtract 1 if one current day and month is less than the day and month of DOB. In case, you get a datatype mismatch error, use STR_TO_DATE(member_dob, '%Y-%M-%d') to convert the string DOB to DATETIME DOB.
