Executes the SQL statement in this PreparedStatement object, which must be an SQL Data Manipulation Language (DML) statement, such as INSERT, UPDATE or DELETE; or an SQL statement that returns nothing, such as a DDL statement.

Usage

From source file:Main.java

public static void main(String args[]) throws Exception {
    Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
    String URL = "jdbc:odbc:dbname";
    Connection dbConn = DriverManager.getConnection(URL, "user", "passw");
    Employee employee = new Employee(42, "AA", 9);
    ByteArrayOutputStream baos = new ByteArrayOutputStream();
    ObjectOutputStream oos = new ObjectOutputStream(baos);
    oos.writeObject(employee);//from w  w  w .j a  v  a2 s  .  c  o  m
    byte[] employeeAsBytes = baos.toByteArray();
    PreparedStatement pstmt = dbConn.prepareStatement("INSERT INTO EMPLOYEE (emp) VALUES(?)");
    ByteArrayInputStream bais = new ByteArrayInputStream(employeeAsBytes);
    pstmt.setBinaryStream(1, bais, employeeAsBytes.length);
    pstmt.executeUpdate();
    pstmt.close();
    Statement stmt = dbConn.createStatement();
    ResultSet rs = stmt.executeQuery("SELECT emp FROM Employee");
    while (rs.next()) {
        byte[] st = (byte[]) rs.getObject(1);
        ByteArrayInputStream baip = new ByteArrayInputStream(st);
        ObjectInputStream ois = new ObjectInputStream(baip);
        Employee emp = (Employee) ois.readObject();
    }
    stmt.close();
    rs.close();
    dbConn.close();
