用来代替SQLSERVERAGENT的VBS脚本。

今天一台MSSQL2000出问题，SQLSERVERAGENT服务又启不过来，胡乱撮写的一个脚本。

\'*******************************************************************
\' 目的：当MSSQL的SQLSERVERAGENT启不过来时，可以用这个脚本来备份全部数据库,也可以做成计划任务来执行
\' 注意还原master数据库要用单用户启动MSSQL
\'*******************************************************************

dim spath
spath="E:\sqldatabackup\db\" \'请注意修改备份路径

dim backpath
backpath=spath & cstr(date() &  hour(now) &  minute(now) & second(now)) & "\"
deletefile(spath & "all.sql")

CreateFolderDemo()
strContent = ExportData
Call LogToFile(strContent, "all.sql")

\'---------------------------------
Set shell = WScript.CreateObject("WScript.Shell")
cmd = "osql -E -i all.sql"
Shell.Run cmd, 1, True
Set shell = Nothing
\'---------------------------------

\'Wscript.Echo "完成！"

\'新建文件夹
 Function   CreateFolderDemo()     
      Dim   fso,   f   
      Set   fso   =   CreateObject("Scripting.FileSystemObject")   
      Set   f   =   fso.CreateFolder(backpath & "")   
      CreateFolderDemo   =   f.Path 
      Set fso = Nothing  
  End   Function   

\'删除文件
function deletefile(filename) 
	if filename<>"" then 
	Set fso = CreateObject("Scripting.FileSystemObject")
	if fso.FileExists(filename) then 
	fso.DeleteFile filename 
	else 
	\' "<script>alert(\'\'该文件不存在\'\');</script>" 
	end if 
	end if 
	Set fso = Nothing
end function 

\'写文件
Function LogToFile(strContent,strFileName)
	Const ForReading = 1, ForWriting = 2,ForAppending = 8
	Dim fso, f
	Set fso = CreateObject("Scripting.FileSystemObject")
	Set f = fso.OpenTextFile(strFileName, ForAppending, True)
	f.WriteLine strContent
        Set fso = Nothing
End Function

\'生成备份脚本
Function ExportData()
	Dim strConn,strSql,strData
	Dim objConn,objRs
	
	strConn = "Provider=sqloledb;Data Source=(local);Initial Catalog=master;Integrated Security=SSPI;"
	Set objConn = CreateObject("ADODB.Connection")
	objConn.Open strConn
	
	\'strSql = "SELECT name,filename FROM sysdatabases"
	strSql = "SELECT name FROM sysdatabases"
	Set objRs = objConn.Execute(strSql)
	If NOT objRs.EOF Then
		While NOT objRs.EOF
	     strData = strData & "backup database [" & objRs(0).value &"] to disk=\'" &  backpath & objRs(0).value  & ".bak\'" &  vbCrLf & "GO" & vbCrLf
		 objRs.MoveNext
		Wend
	End If
	
	If Err.Number <> 0 Then
		ExportData = Err.Description
	Else
		ExportData = strData
	End If
	objRs.Close
	objConn.Close
	Set objRs = Nothing
	Set objConn = Nothing
End Function
