Iif Formula

[Tischtennisbal]

I'm looking for a formula to convert data.

The table Products contains a column called "Indexed products" in which every product have (or don't have) a percentage.

Using the iif formula, I want to "convert" the data into yes (Y) or no (N).
E.g. Product 1 = 5%, then it should be Yand if no percentage is stated than N.

So far i have this written in the criteria in the query:

IIf([Products]![Indexed product]>0;"Y";"N")

Only the formula doesn't work... It says "Data mismatch in criteria expression"

Who knows the answer?!!

Try :-

IIf(IsNull([Products]![Indexed product]), "N", "Y")

And be careful where you assign it.
The result is a string expression so if you assign it to a number or date field you will get

Data mismatch in criteria expression

The data type of "Indexed products" is indeed Number, but the error (data mismatch...) remains. If there another solution to my problem?

[NeoPa]

What do you have on the line before the IIf(...) bit?

[Tischtennisbal]

Nothing.

I've put

IIf(IsNull([Indexed product]);"N";"Y")

in the criteria range of "Indexed product" (in the query).

No other info or formulas are added to the criteria. (I hope this is what you mean.)

Convert the Percentage to a string, Str([YourField]) then perform your if test on that.
ConvertToString: Str([Percentage])

YesOrNo: IIf([ConvertToString]=0,"N","Y")

Tischtennisbal,

Open your query for design, convert view to SQL (SQL View from the View menu), and then copy what you see into this thread so I get a clue as to what you're trying to say.

NB If you keep changing the code from what I put in (',' converted to ';') it will NEVER work for you.
Let the clipboard be your friend - COPY & PASTE!

SQL CODE:

SELECT Spend.[3Po product code], Products.ProductName, Products.Category, Profit_centre.[Profit centre code], Profit_centre.Region, Spend.[Local Supplier name], Supplier.[3PO Supplier name], Mothercompany.Mothercompanyname, Spend.[3PO Agreement number], Spend.[Delivery date], Spend.[Volume delivered KG], Spend.[Invoiced amount EUR], Spend.[Total spend DDP/EUR], Products.[Indexed product]
FROM (Mothercompany INNER JOIN Supplier ON Mothercompany.Mothercompanycode = Supplier.Mothercompanycode) INNER JOIN (Profit_centre INNER JOIN (Products INNER JOIN Spend ON Products.Code = Spend.[3Po product code]) ON Profit_centre.[Profit centre code] = Spend.PcCode) ON Supplier.[Supplier code] = Spend.[3PO supplier code]
WHERE (((Products.[Indexed product])=IIf(IsNull([Indexed product]),"N","Y")));

I hope that is useful to you. I use the output to calculate savings in excel, but the information comes from this query.

The only thing needed is access to convert the percentages to Y or N.

I have no clue, I aint brilliant with Access. My hopes are on you!

Thanks for helping! :-)

OK What you are trying to do doesn't make any sense:

Try this instead...

 
SELECT Spend.[3Po product code], 
Products.ProductName, 
Products.Category, 
Profit_centre.[Profit centre code], 
Profit_centre.Region, 
Spend.[Local Supplier name], 
Supplier.[3PO Supplier name], 
Mothercompany.Mothercompanyname, 
Spend.[3PO Agreement number], 
Spend.[Delivery date], 
Spend.[Volume delivered KG], 
Spend.[Invoiced amount EUR], 
Spend.[Total spend DDP/EUR], 
IIf(IsNull([Indexed product]),"N","Y") As Indexed
FROM (Mothercompany INNER JOIN Supplier ON Mothercompany.Mothercompanycode = Supplier.Mothercompanycode) INNER JOIN (Profit_centre INNER JOIN (Products INNER JOIN Spend ON Products.Code = Spend.[3Po product code]) ON Profit_centre.[Profit centre code] = Spend.PcCode) ON Supplier.[Supplier code] = Spend.[3PO supplier code]);

Unfortnunately it gives an error. "Syntax error in FROM clause"

[PEB]

So pls tell us what are the values of [Products]![Indexed product]

If the values are true or false:

IIf(nz([Products]![Indexed product])>0;-1;0)

or

IIf(nz([Products]![Indexed product])<>0;True;False)

but you don't have but that this is equal to [Products]![Indexed product]

coz there isn't evident logic...
