Esempi
Example #1 MongoDB\Driver\WriteResult::getWriteErrors() with a single error
<?php
$manager = new MongoDB\Driver\Manager;
/* By default, bulk write operations are executed serially in order and
* execution will stop after the first error.
*/
$bulk = new MongoDB\Driver\BulkWrite;
$bulk->insert(['_id' => 1]);
$bulk->insert(['_id' => 2]);
$bulk->insert(['_id' => 2]);
$bulk->insert(['_id' => 3]);
$bulk->insert(['_id' => 4]);
$bulk->insert(['_id' => 4]);
try {
$result = $manager->executeBulkWrite('db.collection', $bulk);
} catch (MongoDB\Driver\Exception\BulkWriteException $e) {
var_dump($e->getWriteResult()->getWriteErrors());
}
?>Il precedente esempio visualizzerà qualcosa simile a:
array(1) {
[0]=>
object(MongoDB\Driver\WriteError)#5 (4) {
["message"]=>
string(81) "E11000 duplicate key error collection: db.collection index: _id_ dup key: { : 2 }"
["code"]=>
int(11000)
["index"]=>
int(2)
["info"]=>
NULL
}
}
Example #2 MongoDB\Driver\WriteResult::getWriteErrors() with multiple errors
<?php
$manager = new MongoDB\Driver\Manager;
/* The "ordered" option may be used to allow bulk write operations to continue
* executing after the first error is encountered.
*/
$bulk = new MongoDB\Driver\BulkWrite(['ordered' => false]);
$bulk->insert(['_id' => 1]);
$bulk->insert(['_id' => 2]);
$bulk->insert(['_id' => 2]);
$bulk->insert(['_id' => 3]);
$bulk->insert(['_id' => 4]);
$bulk->insert(['_id' => 4]);
try {
$result = $manager->executeBulkWrite('db.collection', $bulk);
} catch (MongoDB\Driver\Exception\BulkWriteException $e) {
var_dump($e->getWriteResult()->getWriteErrors());
}
?>Il precedente esempio visualizzerà qualcosa simile a:
array(2) {
[0]=>
object(MongoDB\Driver\WriteError)#5 (4) {
["message"]=>
string(81) "E11000 duplicate key error collection: db.collection index: _id_ dup key: { : 2 }"
["code"]=>
