Question

我正在尝试计算Oracle MV中每月的工作日总数

这是我的要求：

CREATE MATERIALIZED VIEW DIM_DATE_MV
BUILD IMMEDIATE
REFRESH COMPLETE ON DEMAND
START WITH sysdate NEXT (TRUNC(sysdate)+1)  + 7 / 24
as SELECT
CAL.DATE_D as ID_DATE,
(CASE WHEN (
    (TRIM(TO_CHAR(CAL.DATE_D,'Day','nls_date_language=english')) IN ('Saturday','Sunday')) OR 
    (TRIM(TO_CHAR(CAL.DATE_D,'DD-MM')) IN ('01-01', '01-05', '08-05', '14-07', '15-08', '01-11', '11-11', '25-12')) OR 
    (TO_CHAR(CAL.DATE_D, 'DD-MM-YYYY') IN  (SELECT TO_CHAR(DOFF.DATE_OFF, 'DD-MM-YYYY') FROM ODSISIC.DAY_OFF DOFF where DOFF.IMPACT='ALL'))
           )  THEN 0 ELSE 1 END) as IS_WORKING_DAY,


(CASE WHEN TO_CHAR(CAL.DATE_D , 'YYYY-MM') = TO_CHAR(CAL.DATE_D , 'YYYY-MM') THEN (Select SUM(IS_WORKING_DAY) from DIM_DATE_MV group by CAL.YEAR_MONTH_NUM) ELSE 0 END)
 as NB_WORKING_DAY_MONTH

FROM ODSISIC.ORACLE_CALENDAR CAL
LEFT JOIN ODSISIC.DAY_OFF DOFF
ON DOFF.DATE_OFF = CAL.DATE_D

IS_WORKING_DAY = 0，如果它是表DATE_OFF中的“假期”，“周末”或“日期”，则该表包含所有年份的年份不同的假期。

我希望NB_WORKING_DAY_MONTH中IS_WORKING_DAY = 1的月份的总和。

如何直接在查询中计算此SUM，而不是为与DAY_OFF表的联接创建中间表？

谢谢：）

明智地思考后，我通过重做SQL查询来解决此问题：

    }
}

我在创建视图之前计算了工作日（这意味着必须在ORACLE_CALENDAR之前输入我的表DATE_OFF）

我添加了一个联接以根据id_month填充表。

现在可以正常工作

尝试从物化视图中的另一列计算SUM
