Hi,

I would like a query in Access that does the following logic:

If ([CTFImport.DOB] >=#01/09/2014#) And [CTFImport.DOB]<=#31/08/2015#) then -5
else If ([CTFImport.DOB] >=#01/09/2013#) And [CTFImport.DOB]<=#31/08/2014#) then -4
else If ([CTFImport.DOB] >=#01/09/2012#) And [CTFImport.DOB]<=#31/08/2013#) then -3
else If ([CTFImport.DOB] >=#01/09/2011#) And [CTFImport.DOB]<=#31/08/2012#) then -2
else If ([CTFImport.DOB] >=#01/09/2010#) And [CTFImport.DOB]<=#31/08/2011#) then -1
else CTFImport.NCyearActual

I can do this in Crystal Reports but I am struggling in Access.. can you help please?

Thanks,

Tom

I think you will need a series of IIF statement which use the Between comparator.

For example:
IIF([CTFImport.DOB] Between #01/09/2014# AND #31/08/2015#,-5, IIF([CTFImport.DOB] Between #01/09/2013# AND #31/08/2014#,-4, IIF([CTFImport.DOB] Between #01/09/2012# AND #31/08/2013#,-3, IIF([CTFImport.DOB] Between #01/09/2011# AND #31/08/2012#,-2, IIF([CTFImport.DOB] Between #01/09/2010# AND #31/08/2011#,-1,CTFImport.NCyearActual)))))

Alternately you could write your own function is VBA and use that.

try:

SELECT
    Switch(
        ([CTFImport.DOB] >=#01/09/2014#) And [CTFImport.DOB]<=#31/08/2015#), -5,
        ([CTFImport.DOB] >=#01/09/2013#) And [CTFImport.DOB]<=#31/08/2014#) , -4,
        ([CTFImport.DOB] >=#01/09/2012#) And [CTFImport.DOB]<=#31/08/2013#), -3,
		([CTFImport.DOB] >=#01/09/2011#) And [CTFImport.DOB]<=#31/08/2012#), -2,

This worked perfect - thank you.

I didn't try the others - I thought it was fair to start with the first suggested one and work down.. but the first one worked great.

Thanks everyone for looking at this for me.

Cheers

Tom

WIth the addition of one test, you can eliminate 5 tests from the formula.

Perhaps better from a performance standpoint.

IIF( [CTFImport.DOB]>=#01/09/2015#,CTFImport.NCyearActual,
IIf([CTFImport.DOB] >=#01/09/2014# ,-5,
IIf([CTFImport.DOB] >=#01/09/2013# ,-4,
IIf([CTFImport.DOB] >=#01/09/2012# ,-3,
IIf([CTFImport.DOB] >=#01/09/2011# ,-2,
IIf([CTFImport.DOB] >=#01/09/2010# ,-1,
 CTFImport.NCyearActual))))))

Since by the fieldname these are probably dates of birth the first test could be eliminated since there shouldn't be any in the data that are greater than 1 Sep 2015.
