Error : ORA-01704: string literal too long

What are you using when operate with CLOB?

In all events you can do it with PL/SQL

DECLARE
  str varchar2(32767);
BEGIN
  str := 'Very-very-...-very-very-very-very-very-very long string value';
  update t1 set col1 = str;
END;
/

Try to split the characters into multiple chunks like the query below and try:

Insert into table (clob_column) values ( to_clob( 'chunk 1' ) || to_clob( 'chunk 2' ) );

It worked for me.


To solve this issue on my side, I had to use a combo of what was already proposed there

DECLARE
  chunk1 CLOB; chunk2 CLOB; chunk3 CLOB;
BEGIN
  chunk1 := 'very long literal part 1';
  chunk2 := 'very long literal part 2';
  chunk3 := 'very long literal part 3';

  INSERT INTO table (MY_CLOB)
  SELECT ( chunk1 || chunk2 || chunk3 ) FROM dual;
END;

Hope this helps.
