Hi - I am trying to create a query to show only fields that have "yes" as the
answer to a yes/no question on a table. I want to use this query to print a
report listing all the items. I realise I will have to insert something in
the criteria section on the query but I am not sure where to find help with
creating criteria.

Can you help please?
 
Yes is stored as a -1 (minus one) and No as 0 (zero).
Total the -1's and change to positive number like this --
Abs(Sum([YourField]))
Or
(Sum([YourField])) * -1
 
I forgot to say, I have put a parameter asking for the container number when
you run the query (that seems to work) and I have tried putting "If"="yes" in
the criteria line but this doesn't seem to exclude no answers when you run
the query.
Click to expand...

To return only records in which the Yes/No field is Yes, simply write
-1
on the query grid's criteria line of that check box column.
If you have additional query criteria, make sure you write the -1 on
the same row as the other column's criteria for an "AND" where clause:
Where [Company] = "XYZ Co." AND CheckBox = -1
If you write the -1 on the next row you will create an "OR" criteria:
Where [Company] = "XYZ Co." OR CheckBox = -1
 
Hi Fred

I tried putting -1 and also =-1 but I still get the full list of items not
only the "yes" items. Any idea where I might be going wrong?

This is the only criteria in the query.

Hi again, I think I have worked out what seems to be happening, if I put the
-1 in the criteria for one field only it shows all the fields of the
container record if it has "yes" in that particular field, but, if I put the
-1 in all the fields and any of the fields are "NO" it does not show any
fields from that container record.

I am thinking of giving up!!

Try putting the -1 on different criteria lines so that you will get matches if
any of the fields is yes.

IF you put the -1 on the same line that means you are "and-ing" the criteria
while if you put the -1 on separate lines you are "or-ing" the criteria.

And means every field must match the criteria
Or means that at least one field must match the criteria.

Thanks for your help, I'm sure I'll be back with more queries over the next
few weeks as I get this thing up and running.
