What I really want is where c.POPU is MAX

SELECT
     s.SCTYPE,
     ROUND(SUM(c.POPU / c.POUEST) * c.POEST / SUM(c.POPU), 4) 'UNIT COST'
     FROM ccode c
     INNER JOIN job j ON c.JOB_ID = j.JOB_ID
     INNER JOIN sccode s ON s.SCCODE_ID = c.SCCODE_ID
     INNER JOIN sctype t ON t.SCTYPE_ID = s.SCTYPE
WHERE j.JOB_ID = 7398
AND c.POPU > 1
GROUP BY t.SCTYPE;

you could add a "simple" condition like this:
SELECT
     s.SCTYPE,
     ROUND(SUM(c.POPU / c.POUEST) * c.POEST / SUM(c.POPU), 4) 'UNIT COST'
     FROM ccode c
     INNER JOIN job j ON c.JOB_ID = j.JOB_ID
     INNER JOIN sccode s ON s.SCCODE_ID = c.SCCODE_ID
     INNER JOIN sctype t ON t.SCTYPE_ID = s.SCTYPE
WHERE j.JOB_ID = 7398
AND c.POPU > 1
and c.popu = ( select max ( x.popu ) from ccode x )
GROUP BY t.SCTYPE;  

Open in new window


this new subquery might need more, especially if you want this for the relevant job


SELECT
     s.SCTYPE,
     ROUND(SUM(c.POPU / c.POUEST) * c.POEST / SUM(c.POPU), 4) 'UNIT COST'
     FROM ccode c
     INNER JOIN job j ON c.JOB_ID = j.JOB_ID
     INNER JOIN sccode s ON s.SCCODE_ID = c.SCCODE_ID
     INNER JOIN sctype t ON t.SCTYPE_ID = s.SCTYPE
WHERE j.JOB_ID = 7398
AND c.POPU > 1
and c.popu = ( select max ( x.popu ) from ccode x where x.job_id = j.job_id )
GROUP BY t.SCTYPE;  

Open in new window


hope this helps

Yes it is. Why does it make sense for me to post some other error?

I think I know the issue. MySQL doens't like spaces with function/brackets
SELECT
     s.SCTYPE,
     ROUND(SUM(c.POPU / c.POUEST) * c.POEST / SUM(c.POPU), 4) 'UNIT COST'
     FROM ccode c
     INNER JOIN job j ON c.JOB_ID = j.JOB_ID
     INNER JOIN sccode s ON s.SCCODE_ID = c.SCCODE_ID
     INNER JOIN sctype t ON t.SCTYPE_ID = s.SCTYPE
WHERE j.JOB_ID = 7398
AND c.POPU > 1
and c.popu = ( select max(x.popu) from ccode x where x.job_id = j.job_id )
GROUP BY t.SCTYPE;
