hi all !
i test my application with share data folder in remote server with vpn
i found that the tradition way is much much faster than the sql statement

use \\server\data\mytable order ac
seek m.ac
do while ac=m.ac
*** get some data and append records into tempcursor....
enddo
sele tempcursor
brow

i try sql statement
sele * from \\server\data\mytable where ac=m.ac into cursor tempcursor
i've found that it takes very long time to show the tempcursor

why ?
