动态创建SQL Server数据库、表、存储过程等架构信息

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：

<!--[if gte vml 1]><v:shapetype id="_x0000_t75" coordsize="21600,21600" o:spt="75" o:preferrelative="t" path="m@4@5l@4@11@9@11@9@5xe" filled="f" stroked="f"> <v:stroke joinstyle="miter" /> <v:formulas> <v:f eqn="if lineDrawn pixelLineWidth 0" /> <v:f eqn="sum @0 1 0" /> <v:f eqn="sum 0 0 @1" /> <v:f eqn="prod @2 1 2" /> <v:f eqn="prod @3 21600 pixelWidth" /> <v:f eqn="prod @3 21600 pixelHeight" /> <v:f eqn="sum @0 0 1" /> <v:f eqn="prod @6 1 2" /> <v:f eqn="prod @7 21600 pixelWidth" /> <v:f eqn="sum @8 21600 0" /> <v:f eqn="prod @7 21600 pixelHeight" /> <v:f eqn="sum @10 21600 0" /> </v:formulas> <v:path o:extrusionok="f" gradientshapeok="t" o:connecttype="rect" /> <o:lock v:ext="edit" aspectratio="t" /> </v:shapetype><v:shape id="_x0000_i1025" type="#_x0000_t75" alt="" style='width:409.5pt; height:231pt'> <v:imagedata src="file:///C:\DOCUME~1\hyrdc\LOCALS~1\Temp\msohtmlclip1\01\clip_image001.jpg" o:href="file:///E:\incoming\HD1\Web%20.Net\优快云技术中心%20动态创建SQL%20Server数据库、表、存储过程等架构信息.files\优快云_Dev_Image_2003-8-181234011.jpg" /> </v:shape><![endif]--><!--[if !vml]--><!--[endif]-->
