Nested SQL - Distinct Load Left Join in one statement - sql

Question

I wanted to left join two queries:
First:
SELECT TIG_TOL.sName AS Maschine,
TIG_TOL.lTolRef,
Max(TIG_JOB.tActBegin) AS MaxvontActBegin
FROM TIG_JOB LEFT JOIN TIG_TOL ON TIG_JOB.lMacRef = TIG_TOL.lTolRef
WHERE (((TIG_JOB.sState)="Run" Or (TIG_JOB.sState)="Ready"))
GROUP BY TIG_TOL.sName, TIG_TOL.lTolRef;
Second:
SELECT TIG_JOB.sName AS Auftrag,
TIG_JOB.lJobRef,
TIG_TOL.sName AS Artikel,
TIG_TOL.sDescript AS Artikel_Bezeichnung
FROM (TIG_JOB LEFT JOIN TIG_TOL_BOK ON TIG_JOB.lJobRef = TIG_TOL_BOK.lJobRef)
LEFT JOIN TIG_TOL ON (TIG_TOL_BOK.lTolRef = TIG_TOL.lTolRef)
AND (TIG_TOL_BOK.lTolTypRef = TIG_TOL.lTolTypRef)
WHERE (((TIG_TOL.lTolTypRef)=10));
Over a left join
on First.MaxvontActBegin = Second.TIG_JOB.tActBegin
AND First.TIG_TOL.lTolRef = Second.TIG_JOB.lMacRef
Is that possible? In Access Im doing it over two queries, where the second is using the first..

Answer 1

I (blindly) added TIG_JOB.tActBegin and TIG_JOB.lMacRef to the 2nd SELECT (hoping they exist) in order to JOIN the two results.
I used SELECT * only because you did not specify the column selection.
SELECT *
FROM
(
SELECT TIG_TOL.sName AS Maschine,
TIG_TOL.lTolRef,
Max(TIG_JOB.tActBegin) AS MaxvontActBegin
FROM TIG_JOB LEFT JOIN TIG_TOL ON TIG_JOB.lMacRef = TIG_TOL.lTolRef
WHERE (((TIG_JOB.sState)="Run" Or (TIG_JOB.sState)="Ready"))
GROUP BY TIG_TOL.sName, TIG_TOL.lTolRef
) AS FirstTable
LEFT JOIN
(
SELECT TIG_JOB.sName AS Auftrag,
TIG_JOB.lJobRef,
TIG_TOL.sName AS Artikel,
TIG_TOL.sDescript AS Artikel_Bezeichnung,
TIG_JOB.tActBegin,
TIG_JOB.lMacRef
FROM (TIG_JOB LEFT JOIN TIG_TOL_BOK ON TIG_JOB.lJobRef = TIG_TOL_BOK.lJobRef)
LEFT JOIN TIG_TOL ON (TIG_TOL_BOK.lTolRef = TIG_TOL.lTolRef)
AND (TIG_TOL_BOK.lTolTypRef = TIG_TOL.lTolTypRef)
WHERE (((TIG_TOL.lTolTypRef)=10))
) AS SecondTable
ON FirstTable.MaxvontActBegin = SecondTable.tActBegin
AND FirstTable.lTolRef = SecondTable.lMacRef`
