MySql.Data.MySqlClient.MySqlException

Question

美好的一天！有人可以帮我弄这个吗？我无法弄清楚出现此错误的原因。我该怎么办？

  

＆＃34;您的SQL语法出错了;检查手册   对应于您的MySQL服务器版本，以便使用正确的语法   靠近＆＃39;）和cdr_datetime BETWEEN＆＃39; 2015-01-01 12：00：00＆＃39; AND＆＃39; 2015-12-29   23：59：59＆＃39;组＆＃39;在第18行＆＃34;

这是我的代码：

Case "employeewithoutdestination"
    Dim newparams(3) As ReportParameter
        newparams(0) = New ReportParameter("CallClassCode", callClassCode)
        newparams(1) = New ReportParameter("DateTimeFrom", startDateTime)
        newparams(2) = New ReportParameter("DateTimeTo", endDateTime)
        newparams(3) = New ReportParameter("Vat", vat)
       rvScreen.LocalReport.SetParameters(newparams)
       rvScreen.LocalReport.Refresh()

    Dim rdsEmployeeWithoutDestination As New ReportDataSource
    Dim daEmployeeWithoutDestination As New EmployeeWithoutDestinationTableAdapter
    Dim dtEmployeeWithoutDestination As New EmployeeWithoutDestinationDataTable

    If String.IsNullOrEmpty(reportFilter) Then
      daEmployeeWithoutDestination.SetWhereClause(String.Format("cdr_site_id = '{0}' and a.employee_id in ({1}) and cdr_datetime BETWEEN '{2}' AND '{3}' group by cdr_date,cdr_time,cdr_call_type_code ORDER BY employee_name", siteId, employeeId, startDateTime, endDateTime))
    Else
      daEmployeeWithoutDestination.SetWhereClause(String.Format("cdr_site_id = '{0}' and a.employee_id in ({1}) and cdr_datetime BETWEEN '{2}' AND '{3}' group by cdr_date,cdr_time,cdr_call_type_code ORDER BY employee_name", siteId, employeeId, startDateTime, endDateTime))
    End If

      daEmployeeWithoutDestination.Fill(dtEmployeeWithoutDestination)

      rdsEmployeeWithoutDestination.Name = "LCSRDBDataSet_EmployeeWithoutDestination"
      rdsEmployeeWithoutDestination.Value = dtEmployeeWithoutDestination
      rvScreen.LocalReport.DataSources.Add(rdsEmployeeWithoutDestination)

提前致谢。
