(no version information, might be only in CVS)db2_next_result -- Requests the next result set from a stored procedure

Описание

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.

Примеры

Пример 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);
}
?>

Результат выполнения данного примера:

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 "
}
