Some not so obvious but imported notes:
1) You must always use the original statement return when fetching the next result set.
2) You can not remove a reference to a previous result set if you wish to access another result set.

(PECL ibm_db2 >= 1.0.0)
db2_next_result — Requests the next result set from a stored procedure
= NULL
A stored procedure can return zero or more result sets. While you handle the first result set in exactly the same way you would handle the results returned by a simple SELECT statement, to fetch the second and subsequent result sets from a stored procedure you must call the db2_next_result() function and return the result to a uniquely named PHP variable.
Параметри
stmt- Подготвена изјава вратена од db2_exec() or db2_execute().
Вратени вредности
Returns a new statement resource containing the next result set if the stored procedure returned another result set. Returns false if the stored procedure did not return another result set.
Примери
Example #1 Calling a stored procedure that returns multiple result sets
In the following example, we call a stored procedure that returns three result sets. The first result set is fetched directly from the same statement resource on which we invoked the CALL statement, while the second and third result sets are fetched from statement resources returned from our calls to the db2_next_result() function.
<?php
$conn = db2_connect($database, $user, $password);
if ($conn) {
$stmt = db2_exec($conn, 'CALL multiResults()');
print "Fetching first result set\n";
while ($row = db2_fetch_array($stmt)) {
var_dump($row);
}
print "\nFetching second result set\n";
$res = db2_next_result($stmt);
if ($res) {
while ($row = db2_fetch_array($res)) {
var_dump($row);
}
}
print "\nFetching third result set\n";
$res2 = db2_next_result($stmt);
if ($res2) {
while ($row = db2_fetch_array($res2)) {
var_dump($row);
}
}
db2_close($conn);
}
