Question

I’m implementing a system login which in database I have this table:

cat_clients

Id    Name    Rfc        Email            P_Name          P_Email          S_Name          S_Email          T_Name          T_Email
_______________________________________________________________________________________________________________________________________
1     Rick    RFC2345    [e-mail]    George      [e-mail]    Daniel     [e-mail]      Fred        [e-mail]
2     Mary    RFC2212    [e-mail]    Brad        [e-mail]      Allan      [e-mail]       Edward      [e-mail]
......
.....
.... more

So, to login success, User must enter ‘Rfc’ and any email (Email, P_Email, S_Email and T_Email). User have these emails because are alternative contacts.

QUERY

SELECT * 
FROM cat_clients
WHERE (Email = '[e-mail]' OR P_Email = '[e-mail]' OR S_Email = '[e-mail]' OR T_Email = '[e-mail]') AND Rfc = 'RFC2345';

But my Query doesn’t work. I hope I explained.

Thanks in advance

try

SELECT * 
FROM cat_clients
WHERE '[e-mail]' IN (Email, P_Email, S_Email, T_Email) AND
      Rfc = 'RFC2345';
