java.sql.Clob is the mapping in the Java programming language for the SQL CLOB type. A SQL CLOB is a built-in type that stores a character large object as a column value in a row of a database table. You can use PreparedStatement.setClob() on both the Oracle and MySQL databases. In Oracle, when a column data type is CLOB, then you can use setClob(). Oracle s CLOB represents character data of a variable length up to 2GB. In MySQL, when a column data type is TINYTEXT with a maximum length of 255 (2^8 - 1) characters, TEXT with a maximum length of 65,535 (2^16 - 1) characters, MEDIUMTEXT with a maximum length of 16,777,215 (2^24 - 1) characters, or LONGTEXT with a maximum length of 4,294,967,295 or 4G (2^32 - 1) characters, then you can use setClob(). The signature of setClob() is as follows: public void setClob(int parameterIndex, java.sql.Clob clob) throws SQLException

This sets the designated parameter to the given Clob object. The driver converts this to a SQL CLOB value when it sends it to the database. The parameters are as follows: parameterIndex: The first parameter is 1, the second is 2, and so on. clob: A java.sql.Clob object that maps a SQL CLOB value. This throws a SQLException if a database access error occurs.

Setting Up the Oracle Database
This shows how to set up the Oracle database: SQL> 2 3 4 create table clob_table ( id VARCHAR(12) NOT NULL PRIMARY KEY, clob_column CLOB default empty_clob() );
Table created. SQL> desc clob_table; Name Null ---------------- -------ID NOT NULL CLOB_COLUMN
Type -----------VARCHAR2(12) CLOB
SQL> insert into clob_table(id, clob_column) values('id-1', 'value-111111'); SQL> insert into clob_table(id, clob_column) values('id-2', 'value-22222222222'); SQL> commit; SQL> select * from clob_table; ID ---id-1 id-2 CLOB_COLUMN ----------------value-111111 value-22222222222
Solution
This class uses PreparedStatement.setClob() to insert a new record into a SQL CLOB column: import java.util.*; import java.io.*; import java.sql.*; import jcb.util.DatabaseUtil; import jcb.db.VeryBasicConnectionManager; public class Demo_PreparedStatement_SetClob { public static void main(String[] args) { System.out.println("--Demo_PreparedStatement_SetCharacterStream begin--"); // read inputs from command line String dbVendor = args[0]; // {"mysql", "oracle" } String id = args[1]; String newID = args[2]; ResultSet rs = null; Connection conn = null; PreparedStatement pstmt = null; try { System.out.println("--Demo_PreparedStatement_SetClob begin--");

// get a database connection object conn = VeryBasicConnectionManager.getConnection(dbVendor); System.out.println("conn="+conn); System.out.println("---------------"); // begin transaction conn.setAutoCommit(false); // prepare blob object from an existing binary column String query1 = "select clob_column from clob_table where id = "; pstmt = conn.prepareStatement(query1); pstmt.setString(1, id); rs = pstmt.executeQuery(); rs.next(); java.sql.Clob clob = (java.sql.Clob) rs.getObject(1); // prepare SQL query for inserting a new row using setClob() String query = "insert into clob_table(id, clob_column) values( , )"; // create PrepareStatement object pstmt = conn.prepareStatement(query); pstmt.setString(1, newID); pstmt.setClob(2, clob); // execute query, and return number of rows created int rowCount = pstmt.executeUpdate(); System.out.println("rowCount="+rowCount); // end transaction conn.commit(); System.out.println("--Demo_PreparedStatement_SetClob end--"); } catch(Exception e){ e.printStackTrace(); System.exit(1); } finally { // release database resources DatabaseUtil.close(rs); DatabaseUtil.close(pstmt); DatabaseUtil.close(conn); } } }
