Catch ex As OdbcException

Answer 1

问题是你两次调用conn.Close（）。保留你的finally块上的Close连接。

Try

    If functionmode = "ADD" Then
                                        //Supposed this is you columnNAmes                                                     //Set parameters                 
        SQLStr = "INSERT INTO boatmast (gBoatType,BoatCode,BoatName,BP, BPM,LDA,bpk,Today,updtime,bpk2,Today2,updtime2) VALUES (@gBoatType,@BoatCode,@BoatName,@BP, @BPM,@LDA,@bpk,@Today,@updtime,@bpk2,@Today2,@updtime2)"

      SQLCmd.Parameters.AddWithValue("@gBoatType",gBoatType)
      //DO OTHER STUFF TIL @updtime2            

    conn.Open()
    SQLCmd.Connection = conn
    SQLCmd.CommandText = SQLStr
    SQLCmd.ExecuteNonQuery() 

  End If
Catch ex As OdbcException
    MsgBox(ex.ToString)
Finally
     If conn.State = ConnectionState.Open Then conn.Close()
End Try

此致

连接没有关闭。连接的当前状态是打开的
