I have a form based on a query, it is a basic Support Call logging form. I have a combo box on the form and I can select Engineers names within that combo box and change the data shown on the form. I have done this with a criteria in the select query ([Forms]![Call Log Listing]![engineer]).
I would like to be able to enter "ALL" in the combo box so as to show all records on the form regardless of Engineer.
Any ideas gratefully rcvd

I must be missing something basic in this, my row source type is AddAllToList and my row source is a Table that contains a list of engineers names. I dont understand where to paste the AddAllToList function on the form....

something like this

select engineernames from tableName

to add <All> to the selection, you have to use a union query as described in the link posted above.

SELECT Username from ENGINEERS
Union
SELECT '<All>'  from ENGINEERS

I am afraid I am still not getting it.
I now can select "ALL" in my combo box, but I do not get any records displayed, I change to an engineers name and I get his jobs.
Must be missing something or just being a little dim. Thanks for your help so far.

Sorry, i am not getting this:
I have a select query that my form that contains the combo box is based on:

SELECT [Call Logging].*, [Call Logging].[Allocated Engineer]
FROM [Call Logging]
WHERE ((([Call Logging].[Allocated Engineer]) Like [Forms]![Call Log Listing]![engineer]));

My row source of the combo box is:

SELECT Username from ENGINEERS
UNION SELECT 'All'  from ENGINEERS;

When I select an Engineer in the combo box my form displays all of that engineers bookings fine, When I select ALL in my combo box I would like to see all engineers bookings.

Thanks for your patience

try this query, copy and paste


SELECT [Call Logging].*
FROM [Call Logging]
Where IIF([Forms]![Call Log Listing]![engineer]="All",[Allocated Engineer], [Call Logging].[Allocated Engineer] = [Forms]![Call Log Listing]![engineer])
