Import Rows Iteratively Until You Retrieve All Data

Working with the dbtoolboxdemo data source, use the rowLimit argument to retrieve

the first two rows of data, and then rerun the import using a while loop, retrieving

two rows at a time. Continue until you have retrieved all data, which occurs when

curs.Data is 'No Data'.

curs = exec(conn,'select productdescription from producttable');

% Initialize rowLimit

rowLimit = 2

% Check for more data. Retrieve and display all data.

while ~strcmp(curs.Data,'No Data')

curs = fetch(curs,rowLimit);

curs.Data(:)

end

rowLimit =

1 2 ... 463 464 465 466 467 468 469 470 471 472 473 ... 683 684
