如果您的数据库类型和版本支持窗口功能，
那么您可以使用ROW_NUMBER来获取一个号码。
一个数字，基于每个FiscalYear的FiscalWeekEnd。
之后，您可以通过条件聚合来进行透视。
SELECT
MAX(CASE WHEN FiscalYear = 'FY17' THEN FiscalWeekEnding END) AS FY17,
MAX(CASE WHEN FiscalYear = 'FY18' THEN FiscalWeekEnding END) AS FY18
FROM
(
SELECT
ROW_NUMBER() OVER (PARTITION BY "Fiscal Year" ORDER BY "Fiscal Week Ending") AS RN,
"Fiscal Year" AS FiscalYear,
"Fiscal Week Ending" AS FiscalWeekEnding
FROM yourtable
WHERE "Fiscal Year" IN ('FY17','FY18')
) q
GROUP BY RN
ORDER BY RN
