Hi
You could simply use, in a scan loop for instance,
tc.CopyToArray(myArray) to copy the initial data of the record in an
array (or a dynarray) and then, in the same scan loop, with a second
TCursor write in your destination table from the array.
If the fields have the same name in the two tables you would use a
dynarray (the field name will be the index) [to be honest you don't even
need the array in this case simply use tc2.Fieldname = tc1.Fieldname],
if not, an array (the index will be the position of the field, 1,2...)
and then tc2.Fieldname = myArray[2] for example to copy the second field
of tc1 in tc2.Fieldname.
Another possible way is to run an insert query (in SQL or QBE) but with
the TCursor approach you can offer a progress bar for example. You have
more control with TCursor.
