db2_next_result
(PECL)
db2_next_result --
Requests the next result set from a stored procedure
说明
resource
db2_next_result ( resource stmt )
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.
返回值
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.
范例
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 "
