Create a drop down lookup list from a table field with ' All' added to the list of values. This example is often used for selecting specific
(or All) records for a report.
The Union query is used in this example and is a very powerful feature of the SQL language. This
example assumes you have read our Microsoft Access
database design
recommendations. Note: Putting a space before the 'A' in All makes this lookup list choice sort to the top. This method is also great for adding a '<<< New Item >>>' choice to the lookup list.
Warning: General warning about union queries - Never try to use aggregate functions (avg, count, sum, etc.) in a union query. It will drop out duplicate groups of records (in Access at least ). More info on this topic: Union Query Downloadable Example
