我收到一个错误 - '将数据类型'int'转换为nvarchar

这是VB6代码：

Private Sub Form_Load()

      If lvRS_Status.RecordCount <> 0 Then
        Dcbo_Status.ListField = "Sts_StatusDesc"
        Dcbo_Status.BoundColumn = "Sts_StatusID"
        Set Dcbo_Status.RowSource = lvRS_Status
      End If

    End If

这是存储过程：

CREATE PROCEDURE DBPrc_SundryDebrorAgewiseDetails(

  @Month as nvarchar,

您的 SP 参数是一个 int ：
@StatusId as int,

...但是您正在针对空字符串 '' 进行测试：
if @StatusId=''
