Hi..
1- In my mySQL DB there is a field named "Whole".. there are many rows..
and every one has the value for the field "Whole".
What I want is to add all these values in all rows for the field "Whole"
then show it on the screen..
I mean by add : 1 + 2 + 3 = 6...
2- I have another filed there also.. named "UserNo" I want every adding
query to this field to include a value in the row for that field = the
latest row's value + 1
For example : if there are three rows in the table.. Row1 : "UserNo"
value = 1
Row2 : "UserNo" value = 2
Row3 : "UserNo" value = 3 I want PHP to get the last row's value for
that field (In this example : 3) then add to it 1.. so it will be 4 and
insert it to the new row..
Regards..
