Oracle CLOB can't insert beyond 4000 character?

Question

How to insert more than 4000 characters to CLOB type column?

--create test table s
create table s
(
      a clob
);
insert into s values(\'>4000 char\')
<         


        

Answer 1

• split the long character string into 4000 character or less chunks
• create clobs for each chunk using to_clob() function
• concatenate the clobs

Here is an example:

insert into  (clob_column)
  values
  (
      to_clob(' <=4000 symbols ')
    ||to_clob(' <=4000 symbols ')
    ||to_clob(' <=4000 symbols ')
    ...
    ||to_clob(' <=4000 symbols ')
  );
