现在好多程序,都是与数据库相关的,因此在做安装的时候,部署数据库看似是一件很复杂的事情。其实就我个人而言,部署数据库是很简单,大致的思路如下:
1. 用本身的DBMS来产生数据库创建的SQL脚本;
2. 接下来就是写程序来执行SQL脚本,从而达到创建数据库的目的。
 
以下用一个举例来说明,数据库服务器用的是SQL Server。
 
首先要在数据库生成好的SQL脚本最前头,加入如下语句:
       use master
GO
      
if exists (select * from sysdatabases where name='mytest')
            drop database mytest
GO
      
create database mytest
GO
      
use mytest
GO
注:其中“mytest”是要创建的数据库名。
 
而程序的代码如下:

        private System.Windows.Forms.Button btnCreateDB;
        ///<summary>

        private System.ComponentModel.Container components = null;
 
        public frmCreateDB()
        {
            //
            // Required for Windows Form Designer support
            //
            InitializeComponent();
 
            //
            // TODO: Add any constructor code after InitializeComponent call
            //
        }
 
        ///<summary>

        ///</summary>
        protected override void Dispose( bool disposing )
        {
            if( disposing )
