MongoDB\Driver\Server::executeWriteCommand — Execute a database command that writes on this server

说明

final public MongoDB\Driver\Server::executeWriteCommand(string $db, MongoDB\Driver\Command $command, ?array $options = null): MongoDB\Driver\Cursor

Executes the command on this server.

This method will apply logic that is specific to commands that write (e.g. » drop). The default value for the "writeConcern" option will be inferred from an active transaction (indicated by the "session" option), followed by the connection URI.

注意: This method is not intended to be used to execute » insert, » update, or » delete commands. Users are encouraged to use MongoDB\Driver\Server::executeBulkWrite() for those operations.

参数

db (string)

The name of the database on which to execute the command.

command (MongoDB\Driver\Command)

The command to execute.

options

**options**
Option	Type	Description
session	MongoDB\Driver\Session	A session to associate with the operation.
writeConcern	MongoDB\Driver\WriteConcern	A write concern to apply to the operation.

警告

If you are using a "session" which has a transaction in progress, you cannot specify a "readConcern" or "writeConcern" option. This will result in an MongoDB\Driver\Exception\InvalidArgumentException being thrown. Instead, you should set these two options when you create the transaction with MongoDB\Driver\Session::startTransaction().

返回值

Returns MongoDB\Driver\Cursor on success.

错误／异常

Throws MongoDB\Driver\Exception\InvalidArgumentException if the "session" option is used with an associated transaction in combination with a "readConcern" or "writeConcern" option.
Throws MongoDB\Driver\Exception\InvalidArgumentException if the "session" option is used in combination with an unacknowledged write concern.
Throws MongoDB\Driver\Exception\InvalidArgumentException on argument parsing errors.
Throws MongoDB\Driver\Exception\ConnectionException if connection to the server fails (for reasons other than authentication).
Throws MongoDB\Driver\Exception\AuthenticationException if authentication is needed and fails.
Throws MongoDB\Driver\Exception\RuntimeException on other errors (e.g. invalid command).

更新日志

版本	说明
PECL mongodb 1.4.4	MongoDB\Driver\Exception\InvalidArgumentException will be thrown if the `"session"` option is used in combination with an unacknowledged write concern.

注释

注意: It is the caller's responsibility to ensure that the server is capable of executing the write operation. For example, executing a write operation on a secondary (excluding its "local" database) will fail.
