Re: [PHP-DB] Multiple rows for one column in a MySQL table?
You haven't to repeat the name field in the telephone numbers table. This table needs another primary key which is not "id". "id" is the foreign key that allow you to have a one to many relationship. It can be (IMHO): Client table: CLIENT_ID NAME FoneNumber table: FONE_IDFONENUMBER CLIENT_ID HTH Jayme. -Mensagem Original- De: Peter J.

Re: [PHP-DB] Multiple rows for one column in a MySQL table?
Even if you normalize your database design, you must still tell it who owns the row. For example, you have a table containing the following columns: id name You have another table that contains the phone numbers: idnamephone number In order to connect the rows via a foreign key, you must have the information in the first table and again in the second table. Normalization only seperates repetative data. If you didn't normalize, your first table would look something like this: idnamephone number 1phone number 2phone number 3 (etc, etc, etc). Peter J.

No. You need to look at normalizing your database if you have this situation.
