Re: adding values together
You appear to be violating the repeating value rules of relational database. Multivalue databases (Pick and Pick like) support this concept but they are rather uncommon now. You probably need to create a related table. Actually, you might want to do a little study on the general idea of relational databases. Not meaning to be negative here because nobody is born with the knowledge.

I know it's easy if they are in separate rows but unfortunately they're not. see the example iditemprice 1 apple 1.00 2 apple 1.00 pear2.00 3 banana 1.00 I need to get the sum for price for id 2.

Re: SQL question
I'm new at SQL so I may be off base, but in traditional programming practice when you want that kind of sort (right justified) you would fill the field with preceding zeros and that would cause the sort that you are seeking. I'm sure that you could suppress the zeros on print with some sort of mask.

This is my first posting to this group and I am just in the initial phases of supporting MySQL as a backend for out application. If the numbers always precede the letters I would split them off into two separate columns and index those columns. The numbers and letters may likely represent something that could be used in your application as separate entities. I may be off base but looks kind of like versioning. Sincerely, Will McCormick -Original Message- From: John Almberg [mailto:[EMAIL PROTECTED]] Sent: Thursday, September 26, 2002 8:05 PM To: Mysql Subject: SQL question I'm trying to sort a table on a character-type field that contains mostly numbers. This field always contains either a number or a number followed by a character. Like '57' or '57a'. I'd like to sort the table *numerically* on this field, not *alphabetically* on this field. That is, I'd like the table to be sorted like: 1 ... 2 ... 2a ... 3 ... 4d ... NOT like: 1 ... 11 ... 111a ... 2a ... 22 ... See what I mean? This is a common problem, I think, when you sort an character type field that contains numbers. The sort comes out all wrong. Is there anyway I can achieve this sort using SQL? The target server is running 3.22.32.

Try leaving out the word local.
