mysql - '/' 应用程序 VB.NET 中的服务器错误

Question

生成报告时出现此错误。它说

You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near ') GROUP BY cdr_id, cdr_extension_no, cdr_datetime, cdr_digits, cdr_destination, ' at line 19

我该如何解决这个问题？我是 vb.net 编程新手。

这是我的代码:

If String.IsNullOrEmpty(reportFilter) Then
   daEmployee.SetWhereClause(String.Format("cdr_site_id = '{0}' AND a.employee_id IN({1}) AND cdr_datetime BETWEEN '{2}' AND '{3}' AND cdr_call_class_code = 'OUTGOING' AND cdr_call_type_id IN({4}) GROUP BY cdr_id, cdr_extension_no, cdr_datetime, cdr_digits, cdr_destination, cdr_charge_amount, cdr_duration_format, cdr_duration_number, cdr_charge_to, department_code, department_description ORDER BY employee_name", siteId, employeeId, startDateTime, endDateTime, callClass, callType))

Else
   daEmployee.SetWhereClause(String.Format("cdr_site_id = '{0}' AND a.employee_id IN({1}) AND cdr_datetime BETWEEN '{2}' AND '{3}' AND cdr_call_class_code = 'OUTGOING' AND cdr_call_type_id IN({4}) GROUP BY cdr_id, cdr_extension_no, cdr_datetime, cdr_digits, cdr_destination, cdr_charge_amount, cdr_duration_format, cdr_duration_number, cdr_charge_to, department_code, department_description ORDER BY employee_name", siteId, employeeId, startDateTime, endDateTime, callClass, callType))
End If

我已经解决了我的问题。问题出在它的 where 子句上。缺少 CDR 日期时间。很抱歉打扰你们中的一些人。感谢您的回复。这是我的代码:

If String.IsNullOrEmpty(reportFilter) Then
   daEmployee.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
   daEmployee.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
