数据字典到SQL语句的转换(使用word与VBA)

一般我们有几种方式对数据库建模：

1.采用PowerDesign或ErWin等建模工具进行建模

2.利用WORD或EXCEL进行建模

使用第一种方式，可以自动导出要生产表的SQL语句，建表比较方便，而对于第二种方式，则可能需要手工建表，其实在WORD中可以用VBA完成对SQL语句的生成，如将下面格式的WORD数据字典生成SQL语句，就可以利用VBA进行

WORD文档样式为：

	Table1
			PK	默认值
Field1		Varchar(50)	是	1
Field2		Int
Field3		Int
Field4		Numeric(18,4)
