Without knowing the code you used, no idea.
And after 256 posts you really ought to know that you need to supply the code without us telling you.

Hi cookiemonster,

Please find the below code

FIND Button:
DECLARE 
    finalstr  VARCHAR2(1000); 
    dfinalstr VARCHAR2(1000); 
BEGIN 
    IF :HOPE_FORECAST_CONTROL.ORG_CODE IS NOT NULL THEN 
      Go_block('HOPE_FORECAST_DATA'); 

      dfinalstr := Get_block_property('HOPE_FORECAST_DATA', default_where); 

      finalstr := 'where ORGANIZATION_CODE = ' ||( ':HOPE_FORECAST_CONTROL.ORG_CODE' ); 

      Set_block_property('HOPE_FORECAST_DATA', default_where, finalstr); 

      Execute_query(); 
    END IF;

POST-QUERY

DECLARE 
    CURSOR c1 IS 
      SELECT organization_code 
      FROM   hope.hope_forecast_data 
      WHERE  fiscal_year = :HOPE_FORECAST_CONTROL.FISCAL_YEAR; 
BEGIN 
    IF :HOPE_FORECAST_CONTROL.FISCAL_YEAR IS NOT NULL THEN 
      OPEN c1; 

      FETCH c1 INTO :HOPE_FORECAST_CONTROL.ORG_CODE; 

      CLOSE c1; 
    END IF; 
END;

How many records are returned when you execute

SELECT organization_code 
      FROM   hope.hope_forecast_data 
      WHERE  fiscal_year = :HOPE_FORECAST_CONTROL.FISCAL_YEAR

in SQL*Plus? (Substitute block item reference with real value you choose from a LoV).
If it returns more than one record, then it is rather clear - as you use a cursor, it fetches ONE VALUE (but you don't know which one). Once you run the form - it returns one value. Another time, it returns another value. If you want it always to return the same value, include ORDER BY clause or MAX or MIN functions or some other mechanism you find appropriate.

On the other hand, is the above situation valid? I mean, more than a single record for a fiscal year?

Anyway: first answer my question, then we'll see what to do next.

GROUP BY what? DISTINCT probably does the same, doesn't it? Anyway 4 records are still too many. How can you tell which one fits chosen :HOPE_FORECAST_CONTROL.FISCAL_YEAR? You might need to add additional condition to SELECT's WHERE clause.

How would I know? It is not a problem to select 1 record, there are different ways to do that. Question is: which one of them is correct?

I use POST-QUERY to populate items that don't belong to a table that is a source for that data block. If you did that as well, I guess that it is NOT wrong.

Hi littlefoot,
i used in post-query like :HOPE_FORECAST_CONTROL.FISCAL_YEAR(non-database) and in FIND button i wrote like below

finalstr := 'where FISCAL_YEAR = ' ||( ':HOPE_FORECAST_CONTROL.FISCAL_YEAR' );

Here HOPE_FORECAST_CONTROL is non-database na , so, it retrieve all the data from the DB Block ,I want to retrieve the data from the DB Block any suggestion please?

Thank you

I don't have any; you already know how to create DEFAULT_WHERE, you've been discussing that for weeks now. Besides, what does it have to do with many rows returned by a SELECT statement? As I told you: if possible, include another condition into the WHERE clause.

Or

SELECT max(organization_code)
      FROM   hope.hope_forecast_data 
      WHERE  fiscal_year = :HOPE_FORECAST_CONTROL.FISCAL_YEAR

SELECT min(organization_code)
      FROM   hope.hope_forecast_data 
      WHERE  fiscal_year = :HOPE_FORECAST_CONTROL.FISCAL_YEAR

SELECT organization_code
      FROM   hope.hope_forecast_data 
      WHERE  fiscal_year = :HOPE_FORECAST_CONTROL.FISCAL_YEAR
        AND  rownum = 1

will "fix" the problem, but - once again - it is a truly questionable "solution" until you answer which one of 4 (or 2664) values is the right value.
