Large DB recordset - returns num_rows, but no row data - El Forum - 12-16-2008 [eluser]bwuk[/eluser] Hi, I have a DB query that returns over 50000 results from the DB. If we assume that my function and query looks like Code: function get_all_rec() and then in another method in the class, I have: Code: $qUsers = $this->get_all_rec(); I can then output: Code: echo 'num_rows(): '.$qUsers->num_rows().'<br />'; but when I try and get: Code: echo 'first row, user id: '.$qUsers->row(0)->user_id.'<br />'; codeigniter/php doesn't return anything. The whole script terminates and I don't know why. Has anyone else had this issue with CI?

Large DB recordset - returns num_rows, but no row data - El Forum - 12-16-2008 [eluser]phpserver[/eluser] You will need to have your results as an array and then output userid | first row in a table.That will work.You will find the topic about generating results very useful,take a look. Large DB recordset - returns num_rows, but no row data - El Forum - 12-16-2008 [eluser]bwuk[/eluser] Hi, Unfortunately, this is now on a live site, so I can't check the CI logs (if that's what you meant), as it slows the site down far too much. I've tried changing the return type to result_array(), but still it won't return the user data.

Large DB recordset - returns num_rows, but no row data - El Forum - 12-16-2008 [eluser]bwuk[/eluser] Hi, I'm not wanting to output the data....instead I want to run some code against each other. Think of it as a cron against all users. The only other thing I can think of is to limit it to 1000 each time or something..... Large DB recordset - returns num_rows, but no row data - El Forum - 12-16-2008 [eluser]davidbehler[/eluser] I think running 50 querys that return 1000 rows each might be faster than having one huge query with 50000 rows. But you might have to benchmark to find out. |
