>Yes you only edited the temp cursor. There is no base table. In buffering you just issue tableupdate() but here it's a separate cursor. You should do the update with code. It's cumbersome at first but for large tables and set filter needs, this one execute faster. To make it easier also set buffering on with that cursor so you could loop through modified&added recs.

Cetin, the command

select * from LargeDBFFileOnLAN where .t. into cursor tcTemp

works very slow. It scans whole base table! I have 98 MB dbf file on 10 MB
lan and this runs almost forever!
SQL SELECT works fast only without where clause.

So it is not possible to use select into cursor for fast data selection in
cases where select returns many rows! What to do?
