title: Oracle not able to insert data into varchar2(4000 char) column
body: <p>I use Oracle 12c. I have below table in my DB.</p>
  
  <pre><code>CREATE TABLE TEST_T (COL VARCHAR2(4000 CHAR));
  </code></pre>
  
  <p>I need insert multibyte characters in this table. The character is 3 byte character.<br>
  I am able to insert only 1333 (upto 3999 bytes) characters in table.
  My expectation is to insert upto 1500 multibyte characters but I get  <strong>ORA - 01461</strong>. <br>
  I don't want to change data type to CLOB or LONG.
  Is there any way to use VARCHAR2(4000 CHAR) to achieve this.</p>
  
  <p>Below is the code,</p>
  
  <pre><code>SET SERVEROUTPUT ON
  DECLARE
    LV_VAR CHAR(1):='プ';     -- 3 byte character
    LV_STR VARCHAR2(32000) := '';
  BEGIN
    FOR I IN 1..1500
    LOOP
      LV_STR := LV_STR||LV_VAR;
    END LOOP;
  --
    INSERT INTO TEST_T VALUES (LV_STR);
  END;
  /
  
  
  
  Error report -
  ORA-01461: can bind a LONG value only for insert into a LONG column
  ORA-06512: at line 11
  01461. 00000 -  "can bind a LONG value only for insert into a LONG column"
