Creating a Table with an IDENTITY Column

This section describes how to create a new table with an IDENTITY column for PreparedStatement testing.

IDENTITY column is a nice feature provided by SQL Server that provides auto-incremented sequence values for the specified column in a table. Usually, a primary key column is defined as an IDENTITY column.

In order to try IDENTITY columns and provide a table for PreparedStatement tests, I wrote the following program to create a table called "Profile" with the primary key column defined as an IDENTITY column:

 - Copyright (c) 2015,, All Rights Reserved.
import java.sql.*;
import javax.sql.*;
public class SqlServerIdentityColumn {
  public static void main(String [] args) {
    Connection con = null;
    try { ds 
        = new;
//      ds.setPortNumber(60782);
      con = ds.getConnection();

// Creating a database table
      Statement sta = con.createStatement(); 
      int count = sta.executeUpdate(
        "CREATE TABLE Profile ("
        + " FirstName VARCHAR(20) NOT NULL,"
        + " LastName VARCHAR(20),"
        + " Point REAL DEFAULT 0.0,"
        + " BirthDate DATETIME DEFAULT '1999-12-31',"
        + " ModTime DATETIME DEFAULT '2014-12-31 23:59:59.999')");
      System.out.println("Table created.");

    } catch (Exception e) {

The test program executed correctly:

   -cp .;\local\lib\sqljdbc42.jar

   -cp .;\local\lib\sqljdbc42.jar SqlServerIdentityColumn
Table created.
