MongoDB\Driver\WriteResult::getWriteErrors — Returns any write errors that occurred
この関数にはパラメータはありません。
Returns an array of MongoDB\Driver\WriteError objects for any write errors encountered during the write operation. The array will be empty if no write errors occurred.
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
}
}
