Perhaps an important point: The field used in the table for the
list box is also the primary key. This guarantees that the field
contains DISTINCT values.

There are no repetitions in this field, so all values entered are

To populate a list or combo box, I have been using single field
Seems like it should be possible to use a single table for more
list or combo box. (The SQL statement for selecting a field for a list
or combo box is: SELECT "field name" FROM "table name".) Has anyone
tried this before? Any problems doing this?
In a combo box you "always" want:
SELECT DISTINCT "Field" FROM "Table" ORDER BY "Field"
In a list box you "always" want:
SELECT "Field or Concatenation", "Primary Key"
ORDER BY "Field or Concatenation"
Data field=The form's foreign key
[Example] Relations reflected by list boxes in forms
The benefits I get from this are:
1) If I enter a new value in the field, close the table, and open it
again; the entries have rearranged themselves alphabetically.
2) The entries always appear in alphabetically order in the list box
after clicking the refresh tool in the form.
3) Field A has been replaced with a list box (i.e., Monday,
Tuesday, Wednesday) in a form. (The table for this contains one field
whose values are Monday, Tuesday, and Wednesday.) When field A
appears in a report, the only values showing are Monday, Tuesday, and
If I were to use a table having two fields: ID, Day (i.e.,
1,2,3 for ID & Monday, Tuesday, Wednesday for Day); the form has
shown the Monday, Tuesday, Wednesday values while the reports show 1,
2, 3. Obviously, more has to be included in the SQL than what I wrote
in the beginning. But with the limiting structure of my tables for
list boxes do not require anything more.
