例子 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);
}
?>

上例将输出：
Fetching first result set
array(2) {
[0]=>
string(16) "Bubbles "
[1]=>
int(3)
}
array(2) {
[0]=>
string(16) "Gizmo "
[1]=>
int(4)
}
Fetching second result set
array(4) {
[0]=>
string(16) "Sweater "
[1]=>
int(6)
[2]=>
string(5) "llama"
[3]=>
string(6) "150.00"
}
array(4) {
[0]=>
string(16) "Smarty "
[1]=>
int(2)
[2]=>
string(5) "horse"
[3]=>
string(6) "350.00"
}
Fetching third result set
array(1) {
[0]=>
string(16) "Bubbles "
}
array(1) {
[0]=>
string(16) "Gizmo "
} |
