Message Selector
A client may want to receive subsets of messages. A message selector allows a client to filter the messages it wants to receive by use of a SQL92 string expression in the message header. That expression is applied to properties in the message header (not to the message body content) containing the value to be filtered.
If the SQL expression evaluates to true, the message is sent to the client; if the SQL expression evaluates to false, it does not send the message.
