Find a string within a field

Question

This may be easy but I am new to this so here it goes.  I am trying to find if a string can be found in a mysql database field.
The following will only find exactly match
    <CFQUERY DATASOURCE="databasename">
    SELECT mycontact, userid
    FROM mytable
    WHERE email = #form.email#'
    </CFQUERY>
The following will return result if the field email is contain in the form.email
    <CFQUERY DATASOURCE="databasename">
     SELECT mycontact, userid
     FROM mytable
     WHERE email like '%#form.email#%'
    </CFQUERY>
But these will not give what I want.  I want the reverse of the above.  The email fied can contain MORE than one email addresses.  I want to be able to enter a value i.e. form.email and search the table and find any record in the "email" field that contain form.emal.  Help is appreciated.  I am using MYSQL database.  Thanks.

Answer 1

FIRST OF ALL
Everybody is right, fix the darn database.
SECOND OF ALL
Problem 2 is why you have the four cases.
WHERE
email = '#form.email#' 
this finds the case where there is one email in the field
OR email like '%,#form.email#,%'
this finds emails in the middle of a list.  By putting the comma's in your search prevents [email protected] from matching [email protected] because you are searching for ,[email protected],
OR email like '%,#form.email#'
This finds the email if it is at the end of a list, including the comma in the search for the same reason as the previous case.
OR email like '#form.email#,%'
And finally find the email if it at the beginning of a list.
