vbs如何实现sql查询分析器lcx

这篇文章将为大家详细讲解有关vbs如何实现sql查询分析器lcx，小编觉得挺实用的，因此分享给大家做个参考，希望大家阅读完这篇文章后可以有所收获。

示例：
if (lcase(right(wscript.fullname,11))="wscript.exe") then
echo "Execute it under the cmd.exe Plz! Thx."
echo "code by lcx"
wscript.quit
end If

if wscript.arguments.count<1 then
echo "Usage: cscript sql.vbs showTables e:\hytop.mdb或sql:Provider=SQLOLEDB.1;Server=localhost;User ID=sa;Password=haiyangtop;Database=bbs;"
echo "usage: cscript sql.vbs query 连接字符串 <表名=default:""""> sql语句 <页数=default:1>"
echo "exp:cscript sql.vbs showTables "&Chr(34)&"sql:Provider=SQLOLEDB.1;Server=localhost;User ID=sa;Password=haiyangtop;Database=bbs"&Chr(34)
echo "exp:cscript sql.vbs query "&Chr(34)&"sql:Provider=SQLOLEDB.1;Server=localhost;User ID=sa;Password=haiyangtop;Database=bbs"&Chr(34)&Space(1) &Chr(34)&Chr(34)&Space(1)&Chr(34)&"select * from name"&chr(34)&Space(1) & 1

echo "exp:cscript sql.vbs query "&Chr(34)&"sql:Provider=SQLOLEDB.1;Server=localhost;User ID=sa;Password=haiyangtop;Database=bbs"&Chr(34)&Space(1) &Chr(34)&Chr(34)&Space(1)&Chr(34)&"exec master.dbo.xp_cmdshell 'net user ice hacker /add'--"&chr(34)&Space(1) & 1
end If

Sub chkErr(Err)
If Err Then
echo "错误: " & Err.Description & "错误源: " & Err.Source & vbcrlf
Err.Clear
wscript.quit
End If
End Sub


Sub echo(str)
wscript.echo str
End Sub

Function fixNull(str)
If IsNull(str) Then
str = " "
End If
fixNull = str
End Function

Sub showErr(str)
Dim i, arrayStr
arrayStr = Split(str, "$$")
echo "出错信息:"&vbcrlf
For i = 0 To UBound(arrayStr)
echo (i + 1) & ". " & arrayStr(i) & "

Next
echo vbcrlf
