I use D6, I need a field/column in dbgrid . But the field/column is not data
field on table. So the field/column just buffer field.
I have tried with QUERY, I fill sql like it
SELECT IDBRG,' ' as CODEBRG FROM T1
then property READONLY on field "CODEBRG" , set false. So I can fill the
field. But when I post record so the field back to origin/old value. How to
make it (buffer field)?
