mysql + php question
I built a db with a table, one of the columns is named "received". It has a default of 0, after a user has entered their info this value increases to 1....it's an either 0 or 1 value only. I am trying to find out how to reset that whole column to 0 once all users have entered their info with php. I have been reading up but can't find what I need that won't wipe out the other columns also. Any ideas?
