LEFT JOIN dgmTypeAttributes a50 ON t.typeID = a50.typeID
INNER JOIN invGroups g ON t.groupID = g.groupID
WHERE g.categoryID =23
AND a30.attributeID =30

from
       invTypes t
       left join TL2MaterialsForTypeWithActivity components on

       inner join invTypes r on r.typeID=components.requiredTypeID
where
