UC知道VB编程连接SQL SEVER数据库问题

我运行VB程序后出现[MICROSOFT[ODBC SQL SERVER DRIVER [SQL SERVER]第一行:"from"附近有语法错误
那个语法错误应该在哪儿
还有就是这个类模块中的代码
Public Function getlist(byvalsql As String, combo As ComboBox) As ComboBox
Dim mydboper As New DBOperation
Dim rs As ADODB.Recordset
'建立连接
mydboper.DB_connect
Set rst = mydboper.querysql(sql)
If Not rst.EOF Then
With rst
Do While Not .EOF
combo.AddItem .Fields(0)
.MoveNext
Loop
End With
combo.ListIndex = 0
End If
rst.Close
'关闭连接
mydboper.db_disconnect
getidbyname = tmpid
End Function
中的Set rst = mydboper.querysql(sql)这句话中括号里的SQL有错误
还有个
'声明一个连接
Dim conn As ADODB.Connection
'声明一个数据集对象
Dim rst As ADODB.Recordset
Public Sub DB_connect()
'建立连接
Set conn = New ADODB.Connection
conn.Open Connectstring
End Sub

用OLEDB ,用ADO 连接
Public conn As String '定义连接数据库
conn = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" & App.Path & "数据库名" & ";Persist Security Info=False"
这是连接ACCESS 的
With Adodc1
.ConnectionString = conn
.CommandType = 8
.RecordSource = "select * from 表名"
.Refresh
END WITH
你对比一下难度就发现了.如果连接SQ 的把ADO 的字符 COPY 到CONN 里就可以
GOOD LUCK
