我在学习的过程当中,写了这样的一个语句,可为什么总提示我“用户定义类型未定义”为什么呢?
Public Function ExecuteSQL(ByVal SQL As String, MsgString As String) As ADODB.Recordset
Dim cnn As ADODB.Connection
Dim rst As ADODB.Recordset
Dim sTokens() As String
On Error GoTo ExecuteSQL_Error
sTokens = Split(SQL)
Set cnn = New ADODB.Connection
cnn.Open ConnectString
If InStr("INSERT,DELETE,UPDATE", UCase$(sTokens(0))) Then
cnn.Execute SQL
MsgString = sTokens(0) & " query successful"
Else
Set rst = New ADODB.Recordset
rst.Open Trim$(SQL), cnn, adOpenKeyset, adLockOptimistic
Set ExecuteSQL = rst
MsgString = "查询到" & rst.RecordCount & " 条记录 "
End If
ExecuteSQL_Exit:
Set rst = Nothing
Set cnn = Nothing
Exit Function
ExecuteSQL_Error:
MsgString = "查询错误: " & Err.Description
Resume ExecuteSQL_Exit
End Function
