MongoDB\Driver\Manager::executeBulkWrite — Execute one or more write operations
$namespace
, MongoDB\Driver\BulkWrite $bulk
[, MongoDB\Driver\WriteConcern $writeConcern
] )Executes one or more write operations.
A MongoDB\Driver\BulkWrite can be constructed with multiple write operations of varying types (e.g. updates, deletes, and inserts). The driver will attempt to send similarly type operations to the server at the same time to optimize round trips.
namespaceA fully qualified namespace (databaseName.collectionName)
bulkThe MongoDB\Driver\BulkWrite to execute.
writeConcernOptionally, a MongoDB\Driver\WriteConcern. If none given, default to the Write Concern set by the MongoDB Connection URI.
Returns MongoDB\Driver\WriteResult on success, throws exception (instanceof MongoDB\Driver\Exception) on failure.
Example #1 MongoDB\Driver\Manager::executeBulkWrite() example
<?php
$bulk = new MongoDB\Driver\BulkWrite();
$bulk->insert(array("_id" => 1, "x" => 1));
$bulk->insert(array("_id" => 2, "x" => 2));
$bulk->update(array( "x" => 2), array('$set' => array("x" => 1)), array("multi" => false, "upsert" => false));
$bulk->update(array( "x" => 3), array('$set' => array("x" => 3)), array("multi" => false, "upsert" => true));
$bulk->update(array("_id" => 3), array('$set' => array("x" => 3)), array("multi" => false, "upsert" => true));
$bulk->insert(array("_id" => 4, "x" => 2));
$bulk->delete(array("x" => 1), array("limit" => 1));
$manager = new MongoDB\Driver\Manager("mongodb://localhost:27017");
$writeConcern = new MongoDB\Driver\WriteConcern(MongoDB\Driver\WriteConcern::MAJORITY, 100);
$result = $manager->executeBulkWrite("databaseName.collectionName", $bulk, $writeConcern);
printf("Inserted %d document(s)\n", $result->getInsertedCount());
printf("Matched %d document(s)\n", $result->getMatchedCount());
printf("Updated %d document(s)\n", $result->getModifiedCount());
printf("Upserted %d document(s)\n", $result->getUpsertedCount());
printf("Deleted %d document(s)\n", $result->getDeletedCount());
foreach ($result->getUpsertedIds() as $index => $id) {
printf("upsertedId[%d]: ", $index);
var_dump($id);
}
/* If the WriteConcern could not be fulfilled */
if ($writeConcernError = $result->getWriteConcernError()) {
printf("%s (%d): %s\n", $writeConcernError->getMessage(), $writeConcernError->getCode(), var_export($writeConcernError->getInfo(), true));
}
/* If a write could not happen at all */
foreach ($result->getWriteErrors() as $writeError) {
printf("Operation#%d: %s (%d)\n", $writeError->getIndex(), $writeError->getMessage(), $writeError->getCode());
}
?>
以上例程的输出类似于：
Inserted 3 document(s)
Matched 1 document(s)
Updated 1 document(s)
Upserted 2 document(s)
Deleted 1 document(s)
upsertedId[3]: object(BSON\ObjectID)#5 (1) {
["oid"]=>
string(24) "54d3adc3ce7a792f4d703756"
}
upsertedId[4]: int(3)
