怎么用asp創(chuàng)建sql數(shù)據(jù)表相關(guān)操作

1、-. z下面是利用sql語句創(chuàng)立數(shù)據(jù)庫、表、存儲(chǔ)過程、視圖、索引、規(guī)則、修改表、查看數(shù)據(jù)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 窗體設(shè)計(jì)器生成的代碼 窗體重寫處置以清理組件列表。 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
