在BigQuery中,根据月份日期重复相同的值可以通过使用SQL语句和内置函数来实现。以下是一种可行的方法:
SELECT DATE_TRUNC(date_column, MONTH) AS month_date, value
FROM your_table
SELECT DATE_TRUNC(date_column, MONTH) AS month_date, value, COUNT(*) AS count
FROM your_table
GROUP BY month_date, value
SELECT DATE_TRUNC(date_column, MONTH) AS month_date, value, COUNT(*) AS count
FROM your_table
GROUP BY month_date, value
HAVING COUNT(*) > 1
SELECT month_date, value, count
FROM (
SELECT DATE_TRUNC(date_column, MONTH) AS month_date, value, COUNT(*) AS count
FROM your_table
GROUP BY month_date, value
) AS subquery
WHERE count > 1
