Jak wykonać JOIN z dwóch różnych kolumn do tej samej kolumny w osobnej tabeli?

Oto jak dołączyć do nich tylko raz:

SELECT 
  `logTime`,
  `itemID`,
  `typeName`,
  `actorName`,
  `stationName`,
  `action`,
  `passwordType`,
  `quantity`,
  `oldConfiguration`,
  `newConfiguration` 
FROM
  eve_container_audit 
LEFT JOIN
  invTypes
ON
  eve_container_audit.typeID = invTypes.typeID and
  eve_container_audit.itemTypeID = invTypes.typeID
LEFT JOIN
  staStations
ON
  eve_container_audit.locationID = staStations.stationID

Jeśli chcesz dołączyć do nich dwa razy, użyj aliasu :

SELECT 
  `logTime`,
  `itemID`,
  `typeName`,
  `actorName`,
  `stationName`,
  `action`,
  `passwordType`,
  `quantity`,
  `oldConfiguration`,
  `newConfiguration` 
FROM
  eve_container_audit 
LEFT JOIN
  invTypes
ON
  eve_container_audit.typeID = invTypes.typeID
LEFT JOIN
  invTypes invTypes2
ON
  eve_container_audit.itemTypeID = invTypes2.typeID
LEFT JOIN
  staStations
ON
  eve_container_audit.locationID = staStations.stationID
