I can successfully execute a query if I include a where clause with GameNumber. If I remove the where clause I get a response "No Query Processor Found".
In the HM2 API doc it also indicates:
8. Querying for Hand Histories
It it is possible you may need to retrieve the raw hand history for a specific hand to perform custom computation. HMQL provides a very basic mechanism for the retrieval of the original hand history:
select * from handhistories where GameNumberString="5563124333"
It doesn't seem to include any example where multiple hand histories are fetched. Can you successfully retrieve multiple hand histories using a query with limit? Thanks again for any help!
