SQL Procedure Syntax Part II

ok so I got some help with this SQL syntax earlier but now I need help adding an INNER JOIN to this. I'm new to the SQL writing so I'm trying to understand how to write some of the JOIN statements. The INNER JOIN that I have in there isn't correct and I'm trying to figure out why. Any help would be greatly appreciated!

	SELECT dbo.jomast.fcompany, dbo.joitem.fjobno, dbo.joitem.fpartno, dbo.joitem.fgroup, dbo.joitem.fmqty, dbo.joitem.fmeasure, dbo.joitem.fprodcl, dbo.joitem.fdesc, dbo.jodbom.fbompart, dbo.jodbom.fbomdesc, dbo.jodbom.fqty_iss FROM dbo.jodbom 
LEFT JOIN dbo.joitem ON dbo.joitem.fjobno = dbo.jodbom.fjobno 
INNER JOIN dbo.joitem ON dbo.joitem.fjobno = dbo.jomast.fjobno
WHERE ((dbo.joitem.fprodcl = '01') OR (dbo.joitem.fprodcl = '04') ) AND ((dbo.joitem.fpartno <> 'INDIRECT LABOR') OR (dbo.joitem.fpartno <> 'NOT CLOCKED'));

rough draft ... you missed the join for jomast

SELECT J3.fcompany, J1.fjobno, J1.fpartno, J1.fgroup, J1.fmqty, J1.fmeasure, J1.fprodcl, J1.fdesc, J.fbompart, J.fbomdesc, J.fqty_iss
FROM dbo.jodbom AS J
      LEFT JOIN dbo.joitem AS J1
             ON J.fjobno = J1.fjobno
     INNER JOIN dbo.joitem AS J2
            ON J1.fjobno = dJ2.fjobno
     INNER JOIN dbo.JoMast AS J3
            ON J.fjobno = J3.fjobno
WHERE ((J1.fprodcl = '01') OR (J1.fprodcl = '04') ) AND
            ((J1.fpartno <> 'INDIRECT LABOR') OR (J1.fpartno <> 'NOT CLOCKED'));

Tell us in simple English what your definition of 'correct' is for your situation.  Mind readers we ain't.

>LEFT JOIN dbo.joitem
>INNER JOIN dbo.joitem
For starters (and in Mark's code above), you're referencing table dbo.joitem twice, so when columns are referenced in the SELECT or WHERE clause it doesn't know which 'copy' to use.   In these situations, you'll need to use an alias (J1 and J2 in above code), then everywhere else in the statement use J1. and J2.
