PHP - Manual: MongoDB\Driver\Server::executeQuery
2024-11-14
MongoDB\Driver\Server::executeQuery
(mongodb >=1.0.0)
MongoDB\Driver\Server::executeQuery — Execute a database query on this server
说明
final public MongoDB\Driver\Server::executeQuery(string
$namespace, MongoDB\Driver\Query $query, array $options = array()): MongoDB\Driver\CursorExecutes the query on this server.
注意: The
"readPreference"option does not control the server to which the driver issues the operation; it will always be executed on this server object. Instead, it may be used when issuing the operation to a secondary (from a replica set connection, not standalone) or mongos node to ensure that the driver sets the wire protocol accordingly or adds the read preference to the operation, respectively.

"databaseName.collectionName"). -

-

- Throws MongoDB\Driver\Exception\AuthenticationException if authentication is needed and fails.
- Throws MongoDB\Driver\Exception\RuntimeException on other errors (e.g. invalid query operators).
更新日志
| 版本 | 说明 |
|---|---|
| PECL mongodb 1.4.0 |
The third parameter is now an options array.
For backwards compatibility, this paramater will still accept a
MongoDB\Driver\ReadPreference object.
