Question

我在vb.net中有以下查询，它给出了第二行预期的错误表达式在我的代码中，第二行是＆amp; “来自群组，Group_permissions”＆amp; _ 它突出了＆amp;用蓝色说预期表达？

           Using Grp As New OleDb.OleDbDataAdapter(" select Groups.Group_ID, Count
                                       (Group_PErmissions.Access_ID) as Cnt " & _ 
                                        & " from Groups, Group_Permissions " & _ 
                                  & " where Groups.Group_Id = Group_Permissions.Group_ID " & _ 
                                            & " and Groups.Group_Name = " & "'" & 
                                            Cmb_Groups.Text & "'" & _ 
                                            & " group by Groups.Group_Id ", App_Connection  )
             End Using

 Using Grp As New OleDb.OleDbDataAdapter(" select Groups.Group_ID, Count (Group_PErmissions.Access_ID) as Cnt " & _ 
                                         " from Groups, Group_Permissions " & _ 
                                         " where Groups.Group_Id = Group_Permissions.Group_ID " & _ 
                                         " and Groups.Group_Name = " & "'" & Cmb_Groups.Text & "'" & _ 
                                         " group by Groups.Group_Id ", App_Connection  )
End Using

我没有在VB中测试过其他语法错误。但这应该可以解决您所看到的错误。
