Error : ORA-01704: string literal too long

Question

While I try to set the value of over 4000 characters on a field that has data type CLOB, it gives me this error :

ORA-01704: string lite

Answer 1

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;
