How to display clob column data on page item APEX?

vijayyanJun 21 2017 — edited Jun 21 2017

Hi,

I'm trying to display the clob column on Page Item. but, it shows the below error message:

I've done the following:

1. Created page item with display only.

2. Add plsql returned function into the page item with the below code:

DECLARE

L_CLOB CLOB;

begin

select p_data INTO  l_clob from testdel;

:P2_NEW := L_CLOB;

END;

3. But, it shows as error message.

I would like to return more than 4000 characters. But, no success.

Error computing item source value for page item P2_NEW.

ORA-06502: PL/SQL: numeric or value error
