I think you mean you want the field names from a table instead of the data itself. Not sure why you wouldn't just use the Documenter (Tools -> Analyze -> Documenter), but a straight-up query won't do this.
However, the TableDefs object will expose the field names. Make a button on a form and put this in that button's OnClick event:
Code:
Dim FieldCount As Byte
Dim strFields As String
For FieldCount = 0 To (CurrentDb.TableDefs("YourTableName").Fields.Count - 1)
strFields = strFields & CurrentDb.TableDefs("YourTableName").Fields(FieldCount).Name & vbCrLf
Next
MsgBox strFields
That will produce a list of fields and place them in a message box. There are other ways to do this (enumerating the fields collection for example), but this is straightforward and doesn't require knowing how to use a collection object.
From here, you can do whatever you want with each field name by changing where strFields stores each field name.
