怎么用asp创建sql数据表相关操作

1、-. z下面是利用sql语句创立数据库、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：imports system.dataimports system.data.sqlclientpublic class form1 inherits system.windows.forms.form private connectionstring as string = data source=.;initial catalog=;user id=sa;password=; private reader as sqldatareader = nothing private

2、 conn as sqlconnection = nothing private cmd as sqlmand = nothing private altertablebtn as system.windows.forms.button private sql as string = nothing private createothersbtn as system.windows.forms.button*region windows 窗体设计器生成的代码 窗体重写处置以清理组件列表。 protected overloads overrides sub dispose(byval dispo

3、sing as boolean) if disposing then if not (ponents is nothing) then ponents.dispose() end if end if mybase.dispose(disposing) end sub public sub new() mybase.new() initializeponent() end sub private ponents as system.ponentmodel.icontainer friend withevents datagrid1 as system.windows.forms.datagrid

4、 friend withevents createdbbtn as system.windows.forms.button friend withevents createtablebtn as system.windows.forms.button friend withevents createspbtn as system.windows.forms.button friend withevents createviewbtn as system.windows.forms.button friend withevents btnaltertable as system.windows.

5、forms.button friend withevents btncreateothers as system.windows.forms.button friend withevents btndroptable as system.windows.forms.button friend withevents btnviewdata as system.windows.forms.button friend withevents btnviewsp as system.windows.forms.button friend withevents btnviewview as system.

6、windows.forms.button private sub initializeponent() me.createdbbtn = new system.windows.forms.button() me.createtablebtn = new system.windows.forms.button() me.createspbtn = new system.windows.forms.button() me.createviewbtn = new system.windows.forms.button() me.btnaltertable = new system.windows.f

7、orms.button() me.btncreateothers = new system.windows.forms.button() me.btndroptable = new system.windows.forms.button() me.btnviewdata = new system.windows.forms.button() me.btnviewsp = new system.windows.forms.button() me.btnviewview = new system.windows.forms.button() me.datagrid1 = new system.wi

8、ndows.forms.datagrid() ctype(me.datagrid1, system.ponentmodel.isupportinitialize).begininit() me.suspendlayout() createdbbtn me.createdbbtn.location = new system.drawing.point(19, 9) = createdbbtn me.createdbbtn.size = new system.drawing.size(104, 23) me.createdbbtn.tabinde* = 0

9、me.createdbbtn.te*t = 创立数据库 createtablebtn me.createtablebtn.location = new system.drawing.point(139, 9) = createtablebtn me.createtablebtn.tabinde* = 1 me.createtablebtn.te*t = 创立表 createspbtn me.createspbtn.location = new system.drawing.point(230, 9) = cr

10、eatespbtn me.createspbtn.size = new system.drawing.size(104, 23) me.createspbtn.tabinde* = 2 me.createspbtn.te*t = 创立存储过程 createviewbtn me.createviewbtn.location = new system.drawing.point(350, 9) = createviewbtn me.createviewbtn.tabinde* = 3 me.createviewbtn.te*t = 创立视图 btnalt

11、ertable me.btnaltertable.location = new system.drawing.point(441, 9) = btnaltertable me.btnaltertable.tabinde* = 4 me.btnaltertable.te*t = 修改表 btncreateothers me.btncreateothers.location = new system.drawing.point(17, 43) = btncreateothers me.btncreateot

12、hers.size = new system.drawing.size(104, 23) me.btncreateothers.tabinde* = 5 me.btncreateothers.te*t = 创立规则和索引 btndroptable me.btndroptable.location = new system.drawing.point(138, 43) = btndroptable me.btndroptable.tabinde* = 6 me.btndroptable.te*t = 删除表 btnviewdata me.btnviewd

13、ata.location = new system.drawing.point(351, 43) = btnviewdata me.btnviewdata.tabinde* = 7 me.btnviewdata.te*t = 查看数据 btnviewsp me.btnviewsp.location = new system.drawing.point(230, 43) = btnviewsp me.btnviewsp.size = new system.drawing.size(104, 23) me.btnviews

14、p.tabinde* = 8 me.btnviewsp.te*t = 查看存储过程 btnviewview me.btnviewview.location = new system.drawing.point(443, 43) = btnviewview me.btnviewview.tabinde* = 9 me.btnviewview.te*t = 查看视图 datagrid1 me.datagrid1.datamember = me.datagrid1.headerforecolor = system.drawing.systemcolors.co

15、ntrolte*t me.datagrid1.location = new system.drawing.point(20, 76) = datagrid1 me.datagrid1.size = new system.drawing.size(500, 183) me.datagrid1.tabinde* = 10 form1 me.autoscalebasesize = new system.drawing.size(5, 13) me.clientsize = new system.drawing.size(538, 281) me.controls.

16、addrange(new system.windows.forms.control() me.datagrid1, me.btnviewview, _ me.btnviewsp, me.btnviewdata, me.btndroptable, me.btncreateothers, me.btnaltertable, _ me.createviewbtn, me.createspbtn, me.createtablebtn, me.createdbbtn) = form1 me.te*t = 动态创立sql server数据库、表、存储过程等架构信息 ctype(me.dat

17、agrid1, system.ponentmodel.isupportinitialize).endinit() me.resumelayout(false) end sub*end region 创立数据库 private sub createdbbtn_click(byval sender as system.object, byval e as system.eventargs) _ handles createdbbtn.click conn = new sqlconnection(connectionstring) 翻开连接 if conn.state connectionstate

18、.open then conn.open() end if mydatabase为数据库名称 dim sql as string = create database mydatabase on primary (name=mydatabase_data, filename = + _ d:mydatabase.mdf, size=3, + ma*size=5, filegrowth=10%) log on + (name=mydatabase_log, + _ filename=d:mydatabase.ldf,size=3, + ma*size=20,filegrowth=1) cmd =
