Sorry if i´m sendind this question to the wrong place... it´s because i´m new here and i didn´t found the place in the web to send my question over the same that i already did.
But let´s see if you can help me. The situation is like this.
I have a table "customers", then a user go there and change the customer record, for example he changes the zip code column. Then I can know that something changed into the "customer table", and send a full update of that record through the web to the database that i want, but i need to know what column had changed to send a update just for that column. But i do not know in which column his has made that change. So, i need to know the instruction to do this. Something like a specific update for that column modified by the user.
