Report: display column

Question

Hi, I'm newbie, so I need help. I have SQL query report, which always return just one row.
SQL query: SELECT user_id,first_name,last_name,active FROM my_accounts
where user_id=:P5_user_id
Now, if value of field active is 1, then don't display column active, in other case, display column with value 0 (no active).
Please give me working example.
Thanks
Igor

I figured one way to accomplish this. Of course there may other ways as well. Basically what you have is one query for ACTIVE values of "0" and another query for ACTIVE values not equal to "0". Do the following to accomplish it:
1.) Change your query to be of type "SQL QUERY (Pl/Sql Function Body Returning Sql Query)".
2.) Under the Region Source click "Use Generic Column Names (parse query at runtime only)"
3.) Define your Region Source to be:
DECLARE
v_sql1 VARCHAR2(2000):= 'SELECT user_id,first_name,last_name, active '||
' FROM my_accounts '||
' WHERE user_id=:P5_user_id';
v_sql2 VARCHAR2(2000):= 'SELECT user_id,first_name,last_name '||
' FROM my_accounts '||
' WHERE user_id=:P5_user_id';
v_sql VARCHAR2(2000);
BEGIN
FOR rec IN (SELECT active
FROM my_accounts
WHERE user_id=:P5_user_id) LOOP
IF (rec.active = 0) THEN
v_sql := v_sql1;
ELSE
v_sql := v_sql2;
END IF;
END LOOP;
RETURN (v_sql);
END;
I hope that helps,
