RE: [PHP] Adding to a MySql Database
[snip] I have a field on a MySql database that is started with a 0, and I want to add 1 to this field every time a button is pressed on a form. So it should add one every time, like if there is 5 and you press it one time it would have 6. [/snip] 1. SELECT for the current value 2. add 1 to the current value 3. UPDATE the new value HTH!

Re: [PHP] Adding to a MySql Database
Marek's a bit more elegant, but I'm wondering when twelve of us press the button and the database is hit bang, bang, bang. Mightn't a MySQL autoincrement field be better, and let MySQL do the work? mt At 07:32 PM 9/24/2002 +0200, Marek Kilimajer wrote: Or better UPDATE table SET col = col +1 Jay Blanchard wrote: [snip] I have a field on a MySql database that is started with a 0, and I want to add 1 to this field every time a button is pressed on a form.

I agree mt, LET MYSQL DO THE JOB !! Marek's a bit more elegant, but I'm wondering when twelve of us press the button and the database is hit bang, bang, bang.
