Question

how to insert more than 32k xml data into oracle clob column.
xml data is coming from java front end
if we cannot use clob than what are the different options available

Answer 1

Are you facing any issue with my code?
String lateral size error will come when you try to insert the full xml in string format.
public static boolean writeCLOBData(String tableName, String id, String columnName, String strContents) throws DataAccessException{
  boolean isUpdated = true;
  Connection connection = null;
  try {
  connection = ConnectionManager.getConnection ();
  //connection.setAutoCommit ( false );
  PreparedStatement PREPARE_STATEMENT = null;
  String sqlQuery = "UPDATE " + tableName + " SET " + columnName + "  = ?  WHERE ID =" + id;
  PREPARE_STATEMENT = connection.prepareStatement ( sqlQuery );
  // converting string to reader stream
  Reader reader = new StringReader ( strContents );
  PREPARE_STATEMENT.setClob ( 1, reader );
  // return false after updating the clob data to DB
  isUpdated = PREPARE_STATEMENT.execute ();
  PREPARE_STATEMENT.close ();
  } catch ( SQLException e ) {
  e.printStackTrace ();
  finally{
  return isUpdated;
Try this JAVA code.
