上海网站建设-动态创建MSSQL数据库表存储过程

DIV class=guanggao></DIV>下面是利用SQL语句创建数据库、表、存储过程、视图、索引、规则、修改表、查看数据等的方法。所要增加的控件如下：

<TABLE style="BORDER-RIGHT: rgb(204,204,204) 1px dotted; TABLE-LAYOUT: fixed; BORDER-TOP: rgb(204,204,204) 1px dotted; BORDER-LEFT: rgb(204,204,204) 1px dotted; BORDER-BOTTOM: rgb(204,204,204) 1px dotted" cellSpacing=0 cellPadding=6 width="95%" align=center border=0>
