【问题描述】：

查询如下：

  SELECT  tc.CATEGORY_NAME,
  COUNT(dc.CONSULT_ID) AS "TEST_COUNT"
  FROM DOCTOR_CONSULT dc 
  INNER JOIN CONSULT_LABTEST cl 
  on(dc.CONSULT_ID=cl.CONSULT_ID)
  INNER JOIN TEST_SETUP ts
  on(cl.LABTEST_ID=ts.TEST_ID)
  INNER JOIN TEST_CATEGORY tc
  ON (ts.CATEGORY_ID=tc.CATEGORY_ID)
 INNER JOIN OFFICE_DETAILS od 
 on(dc.OFFICE_ID=od.OFFICE_ID)  
 WHERE dc.CONSULT_DATE BETWEEN CURRENT_DATE AND CURRENT_DATE
 AND ts.ACTIVE_STATUS ='Y'
 AND tc.ACTIVE_STATUS ='Y'
 AND od.ACTIVE_STATUS ='Y'
 AND ts.LAB_TYPE IN('L')
 GROUP BY tc.CATEGORY_NAME;

结果如下：

CATEGORY_NAME   TEST_COUNT
Biochemistry        7
Hematology          6
Hormones            1
Clinical Pathology  1

我需要什么

CATEGORY_NAME   TEST_COUNT
Biochemistry        7
Hematology          6
Hormones            1
Clinical Pathology  1
SUM                 15

上面的SQL代码需要修改什么

不确定，如果 SAP 支持 GROUP BY 扩展，但您可以查看 ROLLUP、GROUPING SETS

【解决方案2】：

您可以添加一个没有组的 UNION 来获得您想要的总数：

SELECT  
  tc.CATEGORY_NAME,
  COUNT(dc.CONSULT_ID) AS "TEST_COUNT"
FROM DOCTOR_CONSULT dc 
INNER JOIN CONSULT_LABTEST cl 
on(dc.CONSULT_ID=cl.CONSULT_ID)
INNER JOIN TEST_SETUP ts
on(cl.LABTEST_ID=ts.TEST_ID)
INNER JOIN TEST_CATEGORY tc
ON (ts.CATEGORY_ID=tc.CATEGORY_ID)
INNER JOIN OFFICE_DETAILS od 
on(dc.OFFICE_ID=od.OFFICE_ID)  
WHERE dc.CONSULT_DATE BETWEEN CURRENT_DATE AND CURRENT_DATE
  AND ts.ACTIVE_STATUS ='Y'
  AND tc.ACTIVE_STATUS ='Y'
  AND od.ACTIVE_STATUS ='Y'
  AND ts.LAB_TYPE IN('L')
GROUP BY tc.CATEGORY_NAME

UNION

SELECT 
  'SUM' AS CATEGORY_NAME, 
  COUNT(*) AS TEST_COUNT
FROM DOCTOR_CONSULT dc 
INNER JOIN CONSULT_LABTEST cl 
on(dc.CONSULT_ID=cl.CONSULT_ID)
INNER JOIN TEST_SETUP ts
on(cl.LABTEST_ID=ts.TEST_ID)
INNER JOIN TEST_CATEGORY tc
ON (ts.CATEGORY_ID=tc.CATEGORY_ID)
INNER JOIN OFFICE_DETAILS od 
on(dc.OFFICE_ID=od.OFFICE_ID)  
WHERE dc.CONSULT_DATE BETWEEN CURRENT_DATE AND CURRENT_DATE
  AND ts.ACTIVE_STATUS ='Y'
  AND tc.ACTIVE_STATUS ='Y'
  AND od.ACTIVE_STATUS ='Y'
  AND ts.LAB_TYPE IN('L')
