Performance of Inserting Rows with a ResultSet

This section describes how to measure the performance of inserting rows using a ResultSet object.

Since ResultSet objects can also be used to insert rows, I wrote the following Java sample program to measure the performance of inserting multiple rows using a ResultSet object:

/* SqlServerPerformanceResultSet.java
 - Copyright (c) 2015, HerongYang.com, All Rights Reserved.
 */
import java.sql.*;
public class SqlServerPerformanceResultSet {
  public static void main(String [] args) {
    Connection con = null;
    try {
      com.microsoft.sqlserver.jdbc.SQLServerDataSource ds 
        = new com.microsoft.sqlserver.jdbc.SQLServerDataSource();
      ds.setServerName("localhost");
//      ds.setPortNumber(60782);
      ds.setInstanceName("SQLEXPRESS");
      ds.setDatabaseName("AdventureWorks2014");
      ds.setUser("Herong");
      ds.setPassword("T0pSecret");
      con = ds.getConnection();

// Delete all rows from the table
      Statement sta = con.createStatement();
      sta.executeUpdate("DELETE FROM Profile");

// Start the test
     int count = 10000;
     long t1 = System.currentTimeMillis();

// ResultSet to insert rows
      Statement rs = con.createStatement(
        ResultSet.TYPE_FORWARD_ONLY,
        ResultSet.CONCUR_UPDATABLE);

      ResultSet res = rs.executeQuery("SELECT * FROM Profile");
      res.moveToInsertRow();
      java.util.Random r = new java.util.Random();
      for (int i = 0; i < count; i++) {
        res.updateString("FirstName", 
          Integer.toHexString(r.nextInt(9999)));
        res.updateString("LastName", 
          Integer.toHexString(r.nextInt(999999)));
        res.insertRow();
      }
      rs.close();

// End the test
     long t2 = System.currentTimeMillis();
     System.out.println("ResultSet insert "+count
         +" rows with "+(t2 -t1) +" milliseconds");

      con.close();        
    } catch (Exception e) {
      e.printStackTrace();
    }
  }
}

Here is the result on a Windows 7 system with a 2.5GHz processor, running JDK 1.8, SQL Server 2014 and JDBC Driver 4.2:

ResultSet insert 10000 rows with 9741 milliseconds

Comparing with other type of statements, ResultSet insert rows with the speed as PreparedStatement, see the table below:

Operationg System: Windows 7
CPU speed: 2.5GHz
JVM version: 1.8.0_45
SQL Server: 2014
JDBC driver: JDBC Driver 4.2

Statement           # of inserts   Time in ms.   Comparison
PreparedStatement   10000           9701         100%
Regular Statement   10000          13872         143%
ResultSet           10000           9741         100%

As a comparison, here is the result of SqlServerPerformanceResultSet.java on a Windows XP system with a 997MHz processor, running JDK 1.6, SQL Server 2005 and JDBC Driver 1.0, which was actually faster:

ResultSet insert 10000 rows with 6203 milliseconds
