Question

我尝试在Oracle中编写一个返回特定结果的查询。我有一个查询，该查询结果的单位在特定日期汇总：

   SELECT
        ( (
            SELECT
                MIN(fund_capital)
            FROM
                fund_nav
            WHERE
                calc_date = '1398/04/15'
        ) - (
            SELECT
                SUM(fund_unit) fund_unit
            FROM
                (
                    SELECT
                        customer_id,
                        SUM(fund_unit * (is_purchase * 2 - 1) ) fund_unit
                    FROM
                        fund_order
                    WHERE
                            fo_status_id = 2
                        AND
                            nvl(unit_price,0) > 0
                        AND
                            order_date <= '1398/04/15'
                    UNION ALL
                    SELECT
                        customer_id,
                        SUM(fund_unit) fund_unit
                    FROM
                        fund_premium_license
                    WHERE
                            is_cancelled = 0
                        AND
                            license_date <= '1398/04/15'
                )
        ) ) unit
    FROM
        dual;

通知我查询日期为波斯格式我如何在循环中针对特定日期之间的日期运行此查询，例如在“ 1395/01/01”和“ 137/01/01”之间。我的结果包括2列：

date------unit
1395/01/01------30
1395/01/02------40
1395/01/03------50
etc

编写一个游标，在几天的循环中运行查询
