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:

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

// Creating a database table
      Statement sta = con.createStatement(); 
      int count = sta.executeUpdate(
        "CREATE TABLE Profile ("
        + " ID INTEGER PRIMARY KEY IDENTITY,"
        + " 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.");
      sta.close();

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

The test program executed correctly:

C:\herong>\Progra~1\java\jdk1.8.0_45\bin\javac
   -cp .;\local\lib\sqljdbc42.jar SqlServerIdentityColumn.java

C:\herong>\Progra~1\java\jdk1.8.0_45\bin\java 
   -cp .;\local\lib\sqljdbc42.jar SqlServerIdentityColumn
Table created.
