Question

我有一个输入和输出表，如下所示。输入表每天更新。我需要找到上一个财政年度，上个月，上一季度的值。我在下面编写了查询，以查找上一个财政年度的值。

在ReportFinancialYear ='FY19'的情况下，则Value else null结束为previous_financial_year_value

但是我想使用ReportFinancialYear =当前财政年度1，类似这样。其余类似公式。谁能帮忙。

有点长，但是我测试并完成了工作。

上一个财政年度：

(CASE
    WHEN CAST(REPLACE(UPPER(ReportFinancialYear), "FY", "") AS INT64) + 2000 = EXTRACT(YEAR FROM CURRENT_DATE) - 1 THEN Value
    ELSE NULL
END) AS previous_financial_year_value

上一个财政季度：

(CASE
    WHEN ((CAST(REPLACE(UPPER(ReportFinancialYear), "FY", "") AS INT64) + 2000 = EXTRACT(YEAR FROM CURRENT_DATE) - 1) AND (CAST(REPLACE(UPPER(ReportFinancialQuarter), "Q", "") AS INT64) = 4) AND (EXTRACT(QUARTER FROM CURRENT_DATE) = 1)) OR (CAST(REPLACE(UPPER(ReportFinancialYear), "FY", "") AS INT64) + 2000 = EXTRACT(YEAR FROM CURRENT_DATE) AND (CAST(REPLACE(UPPER(ReportFinancialQuarter), "Q", "") AS INT64) = EXTRACT(QUARTER FROM CURRENT_DATE) - 1)) THEN Value
    ELSE NULL
END) AS previous_financial_quarter_value

上个月：

(CASE
    WHEN ReportMonth = DATE_SUB(DATE_TRUNC(CURRENT_DATE, MONTH), INTERVAL 1 MONTH) THEN Value
    ELSE NULL
END) AS previous_financial_month_value

编辑

由于您还要求提供当前季度：

(CASE
    WHEN (CAST(REPLACE(UPPER(ReportFinancialYear), "FY", "") AS INT64) + 2000 = EXTRACT(YEAR FROM CURRENT_DATE)) AND (CAST(REPLACE(UPPER(ReportFinancialQuarter), "Q", "") AS INT64) = EXTRACT(QUARTER FROM CURRENT_DATE)) THEN Value
    ELSE NULL
END) AS current_financial_quarter_value

注意：：我从previous_financial_quarter_value中错误地复制了查询。现在，它已更新并更正。

根据年，月，季度提取数据
