1、备份
<%
SQL="backup database 数据库名 to disk='"&Server.MapPath("backup")&""&"backuptext.dat"&"'"
set cnn=Server.createobject("adodb.connection")
cnn.open "driver={SQL Server};Server=服务器名;uid=sa;pwd="
cnn.execute SQL
on error resume next
if err<>0 then
response.write "错误:"&err.Descripting
else
response.write "数据备份成功!"
end if
%>
2、恢复
<%
SQL="Restore database 数据库名 from disk='"&Server.MapPath("backup")&""&"backuptext.dat"&"'"
set cnn=Server.createobject("adodb.connection")
cnn.open "driver={SQL Server};Server=服务器名;uid=sa;pwd="
cnn.execute SQL
on error resume next
if err<>0 then
response.write "错误:"&err.Descripting
else
response.write "数据恢复成功!"
end if
%>
注:以上语句是把数据备份到磁盘的backup目录下,文件名为backuptext.dat。
2、ASP中能修改SQL数据库结构吗?
答:ALTER TABLE
名称
ALTER TABLE ― 更改表属性
语法
ALTER TABLE table [ * ]
ADD [ COLUMN ] column type
ALTER TABLE table [ * ]
ALTER [ COLUMN ] column { SET DEFAULT value | DROP DEFAULT }
ALTER TABLE table [ * ]
RENAME [ COLUMN ] column TO newcolumn
ALTER TABLE table
RENAME TO newtable
ALTER TABLE table
ADD table constraint definition
