Multiple Insert Query in Oracle

I had requirement to perform two insert queries in two different tables.

I am using Oracle/Java Combin开发者_如何学运维ation.

What are the options available in this case?

If you're trying to insert the same data into two separate tables you can use a multitable insert like this:

insert all
into table1(a, b)
into table2(a, b)
select 1 a, 2 b from dual;

The most straightforward method is to do two inserts sequentially using the same connection. Assuming that part of your point is that you want the two inserts to occur in the same transaction, then make sure you have disabled autocommit on the connection, and explicitly commit after the second insert.

Another option would be to write an Oracle stored procedure that does the inserts, and call it from Java with a PreparedStatement.

Sample from devdaily.

package com.devdaily.sqlprocessortests;

import java.sql.*;

public class BasicJDBCDemo
{
  Connection conn;

  public static void main(String[] args)
  {
    new BasicJDBCDemo();
  }

  public BasicJDBCDemo()
  {
    try
    {
      Class.forName("com.mysql.jdbc.Driver").newInstance();
      String url = "jdbc:mysql://localhost/coffeebreak";
      conn = DriverManager.getConnection(url, "username", "password");
      doTests();
      conn.close();
    }
    catch (ClassNotFoundException ex) {System.err.println(ex.getMessage());}
    catch (IllegalAccessException ex) {System.err.println(ex.getMessage());}
    catch (InstantiationException ex) {System.err.println(ex.getMessage());}
    catch (SQLException ex)           {System.err.println(ex.getMessage());}
  }

  private void doTests()
  {
    doSelectTest();

    doInsertTest();  doSelectTest();
    doUpdateTest();  doSelectTest();
    doDeleteTest();  doSelectTest();
  }

  private void doSelectTest()
  {
    System.out.println("[OUTPUT FROM SELECT]");
    String query = "SELECT COF_NAME, PRICE FROM COFFEES";
    try
    {
      Statement st = conn.createStatement();
      ResultSet rs = st.executeQuery(query);
      while (rs.next())
      {
        String s = rs.getString("COF_NAME");
        float n = rs.getFloat("PRICE");
        System.out.println(s + "   " + n);
      }
    }
    catch (SQLException ex)
    {
      System.err.println(ex.getMessage());
    }
  }

  private void doInsertTest()
  {
    System.out.print("\n[Performing INSERT] ... ");
    try
    {
      Statement st = conn.createStatement();
      st.executeUpdate("INSERT INTO COFFEES " +
                       "VALUES ('BREAKFAST BLEND', 200, 7.99, 0, 0)");
    }
    catch (SQLException ex)
    {
      System.err.println(ex.getMessage());
    }
  }

  private void doUpdateTest()
  {
    System.out.print("\n[Performing UPDATE] ... ");
    try
    {
      Statement st = conn.createStatement();
      st.executeUpdate("UPDATE COFFEES SET PRICE=4.99 WHERE COF_NAME='BREAKFAST BLEND'");
    }
    catch (SQLException ex)
    {
      System.err.println(ex.getMessage());
    }
  }

  private void doDeleteTest()
  {
    System.out.print("\n[Performing DELETE] ... ");
    try
    {
      Statement st = conn.createStatement();
      st.executeUpdate("DELETE FROM COFFEES WHERE COF_NAME='BREAKFAST BLEND'");
    }
    catch (SQLException ex)
    {
      System.err.println(ex.getMessage());
    }
  }
}

You can check with StoredProcedures and execute with PreparedStatement in JDBC api. That intern will return you two resultSets , which you can get with a method getMoreResults(). You can then process the resultsets separately.
