Assuming you are try to use the Master-Detail Blocks, the Post-Query trigger can issue a select query against the database for data.
Or assuming you are using only one master record, with multiple detail, You can simple issue a select query after the execute_query.
Summary using POST-Query trigger is also possible if you don't mind fetching all records.
