First, you need to normalize your DB, maybe going up to the Third Normal
Form will give you a good DB design.
Second, there is a SQL parameter that let's you display only one record from
many duplicated records, equal records, I guess it is UNIQUE.

Subject: [PHP-DB] begginer question
Hi everyone
I just need something that I believe is very simple only I can't find an
answer for it anywhere
I have a database that each row has a machine, its serial, the customer and
other details. The problem is that I have customers with more than one
machine and I need to query for all the rows, but I don't want the rows that
contain duplicate customers.
The problem is that the only way for me to know the right row from let's say
3 rows that contain the same customer name is the serial number which needs
to be the higher.
So all I need a query to do that.
Thanks in advanced
Ziv
