Hide Report Column Conditionally

Question

Hi All,
I have a report with 12 columns. I want to hide the particular report column if all
the values in that particular column is 0 (Zero).
Can you please help me in achieving the same?
Thanks in advance.
Thanks,
SKJ

Answer 1

Report Attributes > Column Attributes : CBB
For the display condition, you can't refer to the values store in the column. It wouldn't make any sens to know all the values contain in a column at this point. You can use the #CBB# variable for "Column Formatting" and "Column Link" but you can't use it for "Conditional Display".
WRONG :
Value of expression 1 <> Expression 2
and in Expression 1 i put column name i.e. CBB
and Expression2 I put 0.
GOOD :
You have to use a query or a function to determine if the column should be displayed.
Condition Type : PL/SQL FunctionBody Returning a Boolean
Expression 1:
DECLARE
l_retval BOOLEAN := TRUE;
l_sum NUMBER;
BEGIN
SELECT sum(your_column) AS sum_of_CBB
INTO l_sum
[FROM and WHERE of your initial QUERY goes here];
IF l_sum = 0 THEN
l_retval := FALSE;
END IF;
return l_retval;
EXCEPTION
WHEN no_data_found THEN
--should never go here since your report would be empty
null;
END;
