delphi - Invalid use of the keyword Token 'message'

Question

I get this issue in delphi when I am trying to us tQuery and my query is

   SELECT membership_number, message_id, message, target, date_time_creation,
   date_time_display
   FROM MessageMembership
   WHERE membership_number = :membershipnumber    
   ORDER BY date_time_display desc;

I am using following code:

MessageMembershipSelectQuery.ParamByName('membershipnumber').AsString := 
custQuery.FieldByName('cust_code').AsString;
  MessageMembershipSelectQuery.Open;

Let me know what can be done to resolve this
