Hi Joseph
Thanks for the reply, I have to admit I'm a little lost on what you have
said, I have had a look round the net to try and understand it more,
but now I'm ever more lost.
The table is as follows
id INT AUTO_INCREMENT PRIMARY KEY,
date varchar(50),
orderno varchar(50),
store varchar(100),
storename varchar(100),
dnote varchar(50),
status varchar(20),
product varchar(200),
description varchar(200),
ord varchar(50),
del varchar(50),
brand varchar(50),
timestamp varchar(20)
what I need to do is say select from the table all record where timestamp is
between X and Y, and
return 4 variables added up
$notrecognisedcount = total up 'ord' where status equals 'n'
$discontinuedcount = total up 'ord' where status equals 'u'
$validorderscount = total up 'ord' where status not equal 'n' or 'u'
$delivered = total up 'del' where status not equal 'n' or
'u'
Does that make sense?
