Dim Recordset1
Dim Recordset1_numRows

Set Recordset1 = Server.CreateObject("ADODB.Recordset")
Recordset1.ActiveConnection = MM_conn_STRING

If Session("MM_UserAuthorization")="a" Then
Recordset1.Source = "SELECT * FROM dbo.person"
Else
Recordset1.Source = "SELECT * FROM dbo.person where ssyx = '"&Session("MM_UserAuthorization")&"'"
end if
Recordset1.CursorType = 0
Recordset1.CursorLocation = 2
Recordset1.LockType = 1
Recordset1.Open()
Recordset1_numRows = 0

%>
这段代码总是不执行if else中间的语句Recordset1.Source = "SELECT * FROM dbo.person"
而是直接执行else后面的语句谁能帮我看看怎么样修改
想请问两位 我数据库里面的权限字段 权限为a 这个应该怎么写 才能让他执行第一条查询语句呢
我跟踪了Session("MM_UserAuthorization")的值 为‘a’怎样写才能让Session("MM_UserAuthorization")判断成功呢
