/**
|
|
* Transaction to remove older results that violate an updated condition value.
|
|
* <p>
|
|
* How it works:
|
|
* - Select all fulfilled conditions for all players (conditionName when true and not_conditionName when false)
|
|
* - Left join with player value and provider tables when uuids match, and when condition matches a condition in the query above.
|
|
* - Filter the join query for values where the condition did not match any provided condition in the join (Is null)
|
|
* - Delete all player values with IDs that are returned by the left join query after filtering
|
|
*
|
|
* @author AuroraLS3
|
|
* @deprecated Cleanup is now done as part of {@link StorePlayerBooleanResultTransaction}.
