extra field in mysql table!

[fitgura]

Hi all!

I use a ps 1.1.05 revision!!!!

since a few days I works on a problem to export my customer details (id, address, etc...) to a csv file, because our billing software only can feed by csv.......

I did it and looks like work fine

but , for that software I could need some extra information too..... that is why I want to put 2 extra fileds to the end of the ps_address table with a static number and a static text word...... (of course to the end of the table fields)

I try it on localhost demo ps and it didn't cause any worng effect (example: via customer registration)

but im not sure this fields dont't make ps instable or make any problems

That's why I wanna ask somebody who is good in mysql programming or see behind the php of the ps:


Is it safety , and good what I did????

thans for advise!!!
