First I create a database with a table Person containing the following  
columns :  
 - id integer  
 - name string  
 - birthday date  
 - status integer references Status(id)  
  
Then, I create a form containing a tablecontrol. The form creation wizard asks  
me to select the table, then the fields I wish to use. I select all fields from  
table Person.  
  
The wizard guesses the appropriate column types for each column based on its 
SQL type. It creates a numeric column for field "id", a text column for field 
"name", and a date column for field "birthday". 
 
However, the wizard just creates a numeric column for field "status". It would 
provide a much better user experience if instead, it asked me which field from 
table "Status" to display (say, "name"), and created a "list box" field with 
type of list content set to "sql" and list content set to "select name, id from 
Status".
