 <H4>Special Notes</H4>

 <P>When used in a message selector, the <CODE>JMSDeliveryMode</CODE> header 
    field is treated as having the values <CODE>'PERSISTENT'</CODE> and 
    <CODE>'NON_PERSISTENT'</CODE>.

 <P>Date and time values should use the standard <CODE>long</CODE> 
    millisecond value. When a date or time literal is included in a message 
    selector, it should be an integer literal for a millisecond value. The 
    standard way to produce millisecond values is to use 
    <CODE>java.util.Calendar</CODE>.

 <P>Although SQL supports fixed decimal comparison and arithmetic, JMS 
    message selectors do not. This is the reason for restricting exact 
    numeric literals to those without a decimal (and the addition of 
    numerics with a decimal as an alternate representation for 
    approximate numeric values).

 <P>SQL comments are not supported.
