例
例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());}?>
上の例の出力は、 たとえば以下のようになります。
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
}
}
例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());}?>
上の例の出力は、 たとえば以下のようになります。
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"]=>
int(11000)
["index"]=>
int(2)
["info"]=>
NULL
}
[1]=>
object(MongoDB\Driver\WriteError)#6 (4) {
["message"]=>
string(81) "E11000 duplicate key error collection: db.collection index: _id_ dup key: { : 4 }"
["code"]=>
int(11000)
["index"]=>
int(5)
["info"]=>
NULL
}
}
