Performance of Inserting Rows with a Regular Statement

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

To compare the performance result from the previous result with regular Statement objects. I wrote the following Java program to measure the performance of inserting rows using a regular Statement object into an empty table:

/* SqlServerPerformanceRegularStatement.java
 - Copyright (c) 2015, HerongYang.com, All Rights Reserved.
 */
import java.sql.*;
public class SqlServerPerformanceRegularStatement {
  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();

// Regular Statement to insert rows
      Statement rs = con.createStatement();
      java.util.Random r = new java.util.Random();
      for (int i = 0; i < count; i++) {
        rs.executeUpdate("INSERT INTO Profile (FirstName, LastName)"
          +" VALUES ('"+Integer.toHexString(r.nextInt(9999))
          +"', '"+Integer.toHexString(r.nextInt(999999))+"')");
      }
      rs.close();

// End the test
     long t2 = System.currentTimeMillis();
     System.out.println("Regular Statement 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:

Regular Statement insert 10000 rows with 13872 milliseconds

Comparing with PreparedStatement, regular Statement performs much slower than 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%

As a comparison, here is the result of SqlServerPerformanceRegularStatement.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:

Regular Statement insert 10000 rows with 6750 milliseconds
