Class Statement

A single DML statement.

Required. The DML string.
Parameter names and values that bind to placeholders in the DML string. A parameter placeholder consists of the ``@`` character followed by the parameter name (for example, ``@firstName``). Parameter names can contain 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="" a="" sql="" statement="" with="" unbound="">
It is not always possible for Cloud Spanner to infer the right SQL type from a JSON value. For example, values of type ``BYTES`` and values of type ``STRING`` both appear in `params][google.spanner.v1.ExecuteBatchDmlRequest.Statement.params]` as JSON strings. In these cases, ``param_types`` can be used to specify the exact SQL type for some or all of the SQL statement parameters. See the definition of `Type][google.spanner.v1.Type]` for more information about SQL types.
