Can someone convert this Access query to sql please.

SELECT Material.Material, Sum(Material_Location.On_Hand_Qty) AS OH, Sum(IIf([job].[status]=’active’,[order_quantity],0)) AS WIP
FROM (Material LEFT JOIN Material_Location ON Material.Material = Material_Location.Material) LEFT JOIN Job ON Material.Material = Job.Part_Number
WHERE (((Material.Class) Like ‘fghwkb’))
GROUP BY Material.Material
HAVING (((Sum(Material_Location.On_Hand_Qty))>0));

THANKS.

Give this a whirl..
SELECT m.Material, Sum(ml.On_Hand_Qty) AS OH, Sum(CASE WHEN status='active', THEN order_quantity ELSE 0 END) AS WIP
FROM Material m
   LEFT JOIN Material_Location ml ON m.Material = ml.Material
   LEFT JOIN Job j ON m.Material = j.Part_Number
WHERE m.Class Like 'fghwkb'
GROUP BY m.Material
HAVING Sum(ml.On_Hand_Qty) >0

Open in new window

btw I have an article out there on Migrating your Access Queries to SQL Server Transact-SQL which is a grab-bag of Access SQL to T-SQL.

Hope this helps.

typo, remove the comma after status='active'
SELECT m.Material, Sum(ml.On_Hand_Qty) AS OH, Sum(CASE WHEN status='active' THEN order_quantity ELSE 0 END) AS WIP
FROM Material m
   LEFT JOIN Material_Location ml ON m.Material = ml.Material
   LEFT JOIN Job j ON m.Material = j.Part_Number
WHERE m.Class Like 'fghwkb'
GROUP BY m.Material
HAVING Sum(ml.On_Hand_Qty) >0

Now this error:
Msg 209, Level 16, State 1, Line 1
Ambiguous column name 'status'.

So I made it job.status and then got this:
Msg 4104, Level 16, State 1, Line 1
The multi-part identifier "job.status" could not be bound.

>Ambiguous column name 'status'.
In the case block, you'll have to spell out which table's status column you are testing, as the error message means that there are multiple tables in your FROM block that have a column named status.

>So I made it job.status and then got this:
Since I'm using the alias j, try j.status

Alas, the results were not accurate.  Too many loops thru the Job table I believe.  Here are three Access queries which actually bring the correct results.  (first two are called in the third)  If you can convert them to one SQL it would be very appreciated.  I'll award another 500 points, or more, if I can.  Or should I make it a new question?   Thanks.

SELECT Material.Material, Sum(Material_Location.On_Hand_Qty) AS OH
FROM Material LEFT JOIN Material_Location ON Material.Material = Material_Location.Material
WHERE (((Material.Class) Like "fghwkb"))
GROUP BY Material.Material
HAVING (((Sum(Material_Location.On_Hand_Qty))>0))
ORDER BY Material.Material;

SELECT Material.Material, Material.Class, Sum(Job.Order_Quantity) AS SumOfOrder_Quantity
FROM Material LEFT JOIN Job ON Material.Material = Job.Part_Number
WHERE (((Job.Status)="active"))
GROUP BY Material.Material, Material.Class
HAVING (((Material.Class)="fghwkb"));

SELECT Material.Material, Material.Class, [Honeywell on hand].OH, [Honeywell current WIP].SumOfOrder_Quantity
FROM (Material LEFT JOIN [Honeywell current WIP] ON Material.Material = [Honeywell current WIP].Material) LEFT JOIN [Honeywell on hand] ON Material.Material = [Honeywell on hand].Material
WHERE (((Material.Class)="fghwkb"));
