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：

要注意的是在SQL脚本中的“/r/n”，在SQLCommand中是无法识别，因此要替换为空格；其次“GO” 在SQLCommand中也是无法识别，但为了使每条语句都执行，因此我在这里，用“；”来替换。
注：程序的位置和SQL脚本文件的位置为同一目录下，如果觉得不方便的话，可以在我的基础上再延伸。
