params property
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"
