利用代码革新ODBC链接SQL SEVER表[MSSQL防范]

　　在用MDB与SQL SEVER2000链接时,有时需求革新链接表,通过以下代码可以到达目的,此主题的办理参考了网友cwang的代码,并得到了微软工程师Billy Yao 的热情帮忙,在此道谢! iTbulo .comkVpK8

　　　　Function relink()
                Dim db As Database
                Dim tbl As TableDef
                Dim a As String
                Dim b As String
                Dim d As String
               
                a = sa'数据库用户
                b = abc'数据库口令
                d = abcde'数据库名称
                Set db = CurrentDb
                For Each tbl In db.TableDefs
                    If tbl.Attributes = 536870912 Then
                        tbl.Connect = FILEDSN=d:\demo\steel.dsn;UID= & a & ;PWD=
            & b & ;WSID=;DATABASE= & d & ;Network=DBMSSOCN
             '
                        tbl.Attributes = dbAttachSavePWD
                        tbl.RefreshLink
                    End If
                Next
            End Function
            附上微软工程师Billy Yao的解答阐明:
            按照您的描写,我对您的问题解答以下:
            1. DSN=gnts 中gnts是系统DSN的文件名.
            2. UID是用户名,并且它的值由变量a的值决意.PWD是密码,并且它的值由变量b的值决意.
            3. WSID 是指工作站的ID号 (Workstation ID).变量d的值表示数据库的名称. Network=DBMSSOCN
            指TCP/IP所利用的网络库(Network Library).
