Notatki

Informacja: In PHP versions before 5.0.0 you must use ocifetchstatement() instead. This name still can be used, it was left as alias of oci_fetch_all() for downwards compatability. This, however, is deprecated and not recommended.

It looks like passing 0 (zero) as a $maxrows parameter is treated identically as -1 value - all the rows are returned.



OCIfetchstatement($stmt, $res, 1, 0, OCI_FETCHSTATEMENT_BY_ROW)



Tested under: PHP 4.4.3, WinXP pro

If you want to use more than one flag, you need to use the + to connect them:

<?php

oci_fetch_all($stmt, $row, "0", "-1", OCI_ASSOC+OCI_FETCHSTATEMENT_BY_ROW);



?>

The number of rows returned is the number actually fetched, not the number potentially available.  If one limits the number of rows to fetch, the number of rows returned will be bound by that limit.  For example...



$nrows = oci_fetch_all($statement, $results, 0, 1);



would result in a returned value of '0' if there are no rows found for the statement, or '1' if any rows were found, regardless of the number actually present in the database.
