在以下示例中,我们调用一个返回三个结果集的存储过程。第一个结果集直接从我们调用 CALL 语句的同一语句资源中获取,而第二个和第三个结果集从我们对 db2_next_result() 函数调用的语句资源中获取。
<?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);
}
?>
