Class Statement (1.10.0)

A single DML statement.

The DML string can contain parameter placeholders. A parameter placeholder consists of '@' followed by the parameter name. Parameter names consist of any combination of letters, numbers, and underscores. Parameters can appear anywhere that a literal value is expected. The same parameter name can be used more than once, for example: "WHERE id > @msg_id AND id < @msg_id + 100" It is an error to execute an SQL statement with unbound parameters. Parameter values are specified using params, which is a JSON object whose keys are parameter names, and whose values are the corresponding parameter values.
