Product Version: NetBeans IDE 6.0M10 (build 200706260050)

System: Windows XP version 5.1 running on x86; Cp1251; ru_RU (nb)

1. Connect to DB Derby Travel.
2. Create new VWP project.
3. DnD DB table "PERSON" on Designer View.
4. In the window "Navigator" expand tree node "SessionBean1" and select tree subnode "personRowSet".

Result:
- the name of this RowSet-subnode contains SQL satement "SELECT * FROM TRAVEL.PERSON"
- its property "command" in the window "Properties" also contains SQL statement "SELECT * FROM TRAVEL.PERSON"
- SessionBean1.java contains the line
  "personRowSet.setCommand("SELECT * FROM TRAVEL.PERSON");"

5. Use popup menu item "Edit SQL Statement" for selected "personRowSet" (Query Editor window will be opened)

Result:
- Query Editor contains quite another SQL statement:
SELECT ALL "TRAVEL"."PERSON"."PERSONID", 
                    "TRAVEL"."PERSON"."NAME", 
                    "TRAVEL"."PERSON"."JOBTITLE", 
                    "TRAVEL"."PERSON"."FREQUENTFLYER", 
                    "TRAVEL"."PERSON"."LASTUPDATED" 
FROM TRAVEL.PERSON  

- previous SQL statement "SELECT * ..." will be changed to this new SQL satement "SELECT ALL ..."
  in the RowSet-subnode name, in the property "command", in the "SessionBean1.java".

But definitely "SELECT * " isn't quite equal to "SELECT ALL " ("*" != "ALL" in SQL-92)
