>>>Suppose, you have a field in your main table, which may contain a coded value or could be empty. For this field you use a combobox (drop down list). Suppose, you choose something.

>The RowSource for this combobox is a select statement and it selects from Lookups table, which don't have empty record. What should I do in this case?

Add a UNION to the SELECT with empty values for the same fields in the SELECT.
e.g.

SELECT cname, ccity, nage FROM people ;
  UNION ;
 SELECT "" AS cname, "" AS ccity, 0 AS nage ;
  FROM people ;
  INTO CURSOR cuRowSource

As long as the empty row select is the last select, then you shouldn't have the problems that would come up with field widths - like the typical ALLTRIM() problems where the first row returned has a shorter trimmed length than other records
