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) 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:
