Possible causes:

  • The query type is Constituent.  Because participants and guests do not have to be constituents, they do not appear in constituent queries if they are not associated with constituent records.
  • The query filters are set to include participants with a certain number of tickets. Guests do not have tickets, so guests do not appear in the query results.

Try each of the following steps in order until the issue is resolved:

  1. Create a participant query instead of a constituent query
  2. If guests are missing, change the query filters to remove the number of tickets filter. Refer to How to query on participants and guests who are registered for a specific event (BB98111) for more information.
  3. Refer to How to troubleshoot incorrect query results.
