Hello! I have what I hope is a simple enough how-to question for writing a query. I have Table1 with ColumnA, ColumnB, ColumnC, ColumnD, ColumnE, ColumnF, ColumnG, ColumnH, ColumnI, ColumnJ, and ColumnK. All of these columns are either a value 1 or 0 in each record. For ColumnA thru ColumnH, I want to query records that have either 1 or 0 in each of those columns in any combination and for ColumnI thru ColumnK to all equal 0. Can anyone help me figure out the way to write that query in the SQL format?

Thanks John, but I really only understand these queries when using the SQL editor in Access. Can you convert that to SQL for me and paste that?

SELECT 1 AS ColumnA, 1 AS ColumnB, 1 AS ColumnC, 0 AS ColumnJ, 0 AS ColumnL
WHERE (((1)=1) AND ((0)=0)) OR (((1)=1) AND ((0)=0)) OR (((1)=1));

Hi John, that query appears to be using the column names as aliases. I assume it would be ColumnA as 1 (for example), as opposed to 1 As ColumnA. So I can take all the columns that can have either 1 or 0 as values and give them all the same alias?

I think i misread a bit your question ...but the logic is the same
Just select your columns and follow the logic
 ((ColumnA =1 OR ColumnA =0) OR (ColumnB=1 OR ColumnB=0) OR ...(ColumnH=1OR ColumnH=0)) and (ColumnI =0 AND ColumnJ=0 AND ColumnK=0)

Open in new window

You can also use this :
(ColumnA IN(0,1) OR ColumnB IN(0,1) OR...ColumnH IN(0,1))  AND (ColumnI=0 AND ColumnJ=0 AND ColumnK=0))

Open in new window

If you want something more precise then i need a small amount of data along with a desired output

Maybe I'm misunderstanding the question, but if any column from A to H can have 0 or 1 as value and you don't care about the combination for these columns, the query should be simply
Select * from Table1 where ColumnI = 0 and ColumnJ = 0 and ColumnK = 0

Open in new window

Thanks Ferruccio, that's what I am trying to do! For some reason I overcomplicated it when I kept trying to visualize the query. But let me ask you this in follow-up, and this might complicate it to the degree I visualized. For A to H,  if I want to query records where any two of those columns can equal 1 and the rest of those must equal 0, is there a way it can be done?

Having the last three columns = 0?
The fastest way by head could be to query records where the sum of the first 8 columns is >= 2 and the last 3 are 0. This means that at least 2 columns have value 1.

So, on the fly
Select * from Table1 where (ColumnA+ColumnB+ColumnC+ColumnD+ColumnE+ColumnF+ColumnG+ColumnH) >= 2 and (ColumnI = 0 and ColumnJ = 0 and ColumnK = 0)

Open in new window

If you meant just 2 columns = 1 and the others all 0 just use Where (columnA+...) = 2
