Need a query to output a sum of values, dependant on a different value in the record.
i.e.:
My table contains fields "Type of Aircraft" and "Aircrew per aircraft". The values for "Type of Aircraft" are AC-130, A-10, F-16, MH-60, etc.
The values for "Aircrew per Aircraft" are a number based on how many aircrew members are on an aircraft (i.e AC-130 is 14, A-10 is 1, etc).

I want to build a query that will total (sum) all of the "Aircrew per Aircraft", but grouped by the type of aircraft.
Thanks,

Vince
 
Correction to the post above, my fields are "Asset Used" and "# of Aircrew Trained".

Here's where I'm at:

SELECT Sum([# of Aircrew Trained])(IIf([Asset Used]='AC_130H',1,0)), Sum([# of Aircrew Trained])(IIf([Asset Used]='CH-53E',1,0)) AS [CH_53E]
FROM [Mission Report]
WHERE ([Mission Report].[Date Tng Completed] Between #10/1/2008# And #9/30/2009#)

I know this isn't correct, but it might help you figure it out.
 
There are no implicit operators...

(x)(y) is not a product...

(x)*(y) is a product.
 
I think lameid's referring to this snippet:

Sum([# of Aircrew Trained])(IIf([Asset Used]='AC_130H',1,0))


where you need something between

Sum([# of Aircrew Trained])

and

(IIf([Asset Used]='AC_130H',1,0))

perhaps a "*" if you're multiplying or a "," if they're two fields.

Code:
SELECT [Asset Used], Sum([# of Aircrew Trained]) AS NumberOfTrained
FROM [Mission Report]
WHERE [Date Tng Completed] Between #2008-10-01# And #2009-09-30#

Hope This Helps, PH.

Hi PH,
I tried using your code, but it didn't work. Here's what I got:

"You tried to execute that does not include the specified expression 'Asset Used' as part of an aggregate function."

This code gives me the information I'm looking for, but I can't get into my report.


SELECT DISTINCTROW [Mission Report].[Asset Used], Sum([Mission Report].[# of Aircrew Trained]) AS [Sum Of # of Aircrew Trained]
FROM [Mission Report]
WHERE ((([Mission Report].[Date Tng Completed]) Between #10/1/2008# And #9/30/2009#))
GROUP BY [Mission Report].[Asset Used];

If there's a way to show all the results of the query on the report I already have built, that would be great.

Thanks for the help.
Vince
 
Nevermind, I got it.

I made a report from just that query, then in my original report, I added a subreport from the new one. The only problem now is that it doesn't let me do much formatting.

Thanks anyways.
