Calculate sum of column in Table
- Thread starter PiotrG
- Start date
Whats the database back-end ?
You could use an SQL Command with the SUM(Field1) function to acquire the total.
Alternatively (but not ideal) you could run code like :
tpRunTotal := 0;
with Table1 do
begin
First;
while not EOF do
begin
tpRunTotal := tpRunTotal + Table1Field1.AsFloat;
Next;
end; // while not EOF
end; // with Table1 do
Hope that this helps.
