Question

以下两个查询的工作都是相互独立的。我需要将它们合并为一个，并完成以下任务。

计算员工日期范围的发送次数（DATA_CANNON_DISPATCHED）。
计算日期范围内员工已完成的调度数。我已经设置好在php中处理这个问题了。在查询中执行此操作将是一件好事，但不是必需的。
计算日期范围内员工的清算行为代码数量10,35,80。

代码：

/*  1  */
SELECT  COUNT(INCIDENT_NUMBER) AS NTFR
FROM ETA
WHERE CLEARING_ACTION_CODE IN ('10-Trouble Cleared','35-False Report','80-No Trouble Found - C.O.')
AND INCIDENT_NUMBER IN (SELECT INCIDENT_NUMBER
                        FROM  HDESK
                        WHERE DATA_CANNON_DISPATCHED = 'Yes' 
                        AND CUST_EMPLOYEE_ID = 'n9950298' 
                        AND REPORTED_DATE_TIME_RAW_VALUE
                        BETWEEN 1420510400 AND 1420906799)


/* 2 */
SELECT INCIDENT_NUMBER, STATUS,DATA_CANNON_DISPATCHED 
FROM HDESK
WHERE DATA_CANNON_DISPATCHED = 'Yes' 
AND CUST_EMPLOYEE_ID = 'n9950298' 
AND REPORTED_DATE_TIME_RAW_VALUE
BETWEEN 1420510400 AND 1420906799


/*This is what I came up with that works. */
/* 3 */
SELECT H.INCIDENT_NUMBER, H.STATUS,DATA_CANNON_DISPATCHED , CLEARING_ACTION_CODE
FROM ARADMIN.WIN_LT_RPTG_HELP_DESK H, ARADMIN.WIN_LT_RPTG_ETA_APPT_INFO E
WHERE H.DATA_CANNON_DISPATCHED = 'Yes' 
AND H.CUST_EMPLOYEE_ID = 'n9950298' 
AND H.REPORTED_DATE_TIME_RAW_VALUE BETWEEN 1420510400 AND 1420906799
AND H.INCIDENT_NUMBER = E.INCIDENT_NUMBER (+)

Answer 1

试试这个

SELECT COUNT(e.INCIDENT_NUMBER)as NTFR,
       h.INCIDENT_NUMBER, 
       h.STATUS,
       h.DATA_CANNON_DISPATCHED,
       COUNT(e.CLEARING_ACTION_CODE) as CLEARING_ACTION_CODE
FROM ETA e 
INNER JOIN HDESK h 
on e.INCIDENT_NUMBER= h.INCIDENT_NUMBER
WHERE h.DATA_CANNON_DISPATCHED = 'Yes' 
                        AND  e.CLEARING_ACTION_CODE 
  IN ('10-Trouble Cleared','35-False Report','80-No Trouble Found - C.O.')

                        AND h.CUST_EMPLOYEE_ID = 'n9950298' 
                        AND h.REPORTED_DATE_TIME_RAW_VALUE
                        BETWEEN 1420510400 AND 1420906799

GROUP BY e.INCIDENT_NUMBER,e.CLEARING_ACTION_CODE,h.STATUS,h.DATA_CANNON_DISPATCHED

对于给定的emplyoee和句点，您可以使用此查询。我不确定你想要什么，如果出现问题，请尝试删除distinct。

如果您需要以下表格：Id - Dispatches - Completed - Codes 然后通过在id部分中添加select并添加group by子句来轻松转换查询。

select 
    count(distinct incident_number) dispatches,
    count(decode(data_cannon_dispatched, 'Yes', 1)) completed,
    count(distinct clearing_action_code) codes
  from eta e join hdesk h using (incident_number)
  where substr(e.clearing_action_code, 1, 3) in ('10-', '35-', '80-')
    and cust_employee_id = 'n9950298' 
    and reported_date_time_raw_value between 1420510400 and 1420906799

测试数据和结果：

with eta as (select 1 incident_number, '10-Trouble Cleared' clearing_action_code from dual
  union select 2, '10-Trouble Cleared' from dual
  union select 3, '80-No Trouble Found - C.O.' from dual),
hdesk as (
  select 1 incident_number, 'Yes' data_cannon_dispatched, 
    'n9950298' cust_employee_id, 1420510400 reported_date_time_raw_value, 
    5 status from dual
  union select 2, 'Yes', 'n9950298', 1420510401, 6 from dual
  union select 3, 'No', 'n9950298', 1420510402, 6 from dual
  union select 3, 'No', 'aqq50298', 1420510403, 0 from dual)
select 
    count(distinct incident_number) dispatches,
    count(decode(data_cannon_dispatched, 'Yes', 1)) completed,
    count(distinct clearing_action_code) codes
  from eta e join hdesk h using (incident_number)
  where substr(e.clearing_action_code, 1, 3) in ('10-', '35-', '80-')
    and cust_employee_id = 'n9950298' 
    and reported_date_time_raw_value between 1420510400 and 1420906799

结果：

DISPATCHES COMPLETED  CODES
---------- ---------- ---------- 
         3          2          2

注意：

最好将清除操作代码和清除操作说明存储在不同的表中，这样您就不必总是将这些字符串存储在表中。
存储日期的方式有点难以理解; - ）
当你添加一些输入和输出数据时，对于回答的人来说总是更简单。
