Refering ref_codes table from forms

Question

Hi
I am using headstart designer 6i. I created a form in designer. The base table contains a column named 'STATUS'. This column is linked with a defined domain.
Now I want to display abbrevation for the domain values on the form. Whenever I change the display property of status text field on my form, its start giving me error that soft_val called with wrong number of arguments.
It works fine if I change it from text field to text list.
How to make it work with text field.
Regards,
-P

Answer 1

I use several subqueries within a select statement.
These subqueries hold other subqueries. All these subqueries use an alias from the main select:
SELECT      rep.RepID
rep.Rep_Name
          ,(SELECT COALESCE (
                    (SELECT CodeTranslation
FROM T_I18N_CODES_TRANS
WHERE CODEID =
                         (SELECT CODEID
FROM T_I18N_CODES
where CODE = rep.REP_NAME)
                    AND LangChar = 'en'),
                    (SELECT codeTrans.CodeTranslation
                    FROM T_I18N_CODES_TRANS codeTrans
                    INNER JOIN T_Language lang ON lang.LanguageID = codeTrans.codelangID
                    WHERE CODEID =
(SELECT CODEID
FROM T_I18N_CODES
where CODE = rep.REP_NAME)
                    AND codeTrans.LangChar != 'en')
          FROM DUAL) name
FROM Rep
This works fine and I can reference rep.Rep_Name from the great-grandparent, but if I want to go one more level down (another subquery of a subquery I cannot reference that variable from the main select anymore.
Is there a limit somewhere or is there another way of referencing it?Yes there is a limit in outer query you can select only the columns of immediate subquery. You want to select a column of subquery (Say Q2) of subquery(Say Q1) then you will have to select the column in Q2 and Q1 as well ie from inner to outer queries.
