我是SQL的新手.我目前正在开发一个Oracle数据库,并且我创建了一个报告,根据日期范围参数提取数据.
代码如下:
SELECT
DISTINCT C.CUSTOMER_CODE
, MS.SALESMAN_NAME
, SUM(C.REVENUE_AMT) Rev_Amt
FROM
C_REVENUE_ANALYSIS C
, M_CUSTOMER_H MC
, M_SALESMAN MS
WHERE C.COMPANY_CODE = 'W1'
AND C.CUSTOMER_CODE = MC.CUSTOMER_CODE
AND MC.SALESMAN_CODE = MS.SALESMAN_CODE
AND trunc(C.REVENUE_DATE) between to_date(<STARTDATE>,'YYYYMMDD') and to_date(<ENDDATE>,'YYYYMMDD')
AND MS.COMPANY_CODE = '00'
GROUP BY C.CUSTOMER_CODE, MS.SALESMAN_NAME
ORDER BY C.CUSTOMER_CODE, MS.SALESMAN_NAME
由此产生的日期范围为1月1日至4月30日的报告为:
+-----------+--------------+--------------+
|Customer |Salesman Name |Revenue Amount|
+-----------+--------------+--------------+
|Customer 1 |Salesman 1 | 5000.00|
+-----------+--------------+--------------+
|Customer 2 |Salesman 1 | 8000.00|
+-----------+--------------+--------------+
|Customer 3 |Salesman 2 | 300.00|
+-----------+--------------+--------------+ …
