### - (`self`) set_auto_commit(autoCommit = nil) { ... }

Sets the auto commit flag for this connection. True by default.

Parameters:

- autoCommit (`true`, `false`) (defaults to: `nil`) —
  the autoCommit flag, true by default.

Yields:

- the handler which is called once this operation completes.

Returns:

- (`self`)

Raises:

- (`ArgumentError`)

      raise ArgumentError, "Invalid arguments when calling set_auto_commit(#{autoCommit})"
    end

### - (`self`) set_options(options = nil)

Sets the desired options to be applied to the current connection when statements are executed. The options are not applied globally but applicable to the current connection. For example changing the transaction isolation level will only affect statements run on this connection and not future or current connections acquired from the connection pool. This method is not async in nature since the apply will only happen at the moment a query is run.

Parameters:

- options (`Hash`) (defaults to: `nil`) —
  the options to modify the unwrapped connection.

Returns:

- (`self`)

Raises:

- (`ArgumentError`)

### - (`self`) set_query_timeout(timeoutInSeconds = nil)

Sets a connection wide query timeout. It can be over written at any time and becomes active on the next query call.

Parameters:

- timeoutInSeconds (`Fixnum`) (defaults to: `nil`) —
  the max amount of seconds the query can take to execute.

Returns:

- (`self`)

Raises:

- (`ArgumentError`)

### - (`self`) set_transaction_isolation(isolation = nil) { ... }

Attempts to change the transaction isolation level for this Connection object to the one given. The constants defined in the interface Connection are the possible transaction isolation levels.

Parameters:

- isolation (`:READ_UNCOMMITTED`, `:READ_COMMITTED`, `:REPEATABLE_READ`, `:SERIALIZABLE`, `:NONE`) (defaults to: `nil`) —
  the level of isolation

Yields:

- the handler called when this operation completes.

Returns:

- (`self`)

Raises:

- (`ArgumentError`)

### - (`self`) update(sql = nil) { ... }

Executes the given SQL statement which may be an `INSERT`, `UPDATE`, or `DELETE` statement.

Parameters:

- sql (`String`) (defaults to: `nil`) —
  the SQL to execute. For example `INSERT INTO table ...`

Yields:

- the handler which is called once the operation completes.

Returns:

- (`self`)

Raises:
