Mengatur variabel Big Query seperti mysql

Anda bisa menggunakan klausa WITH. Ini tidak ideal, tetapi menyelesaikan pekerjaan.

-- Set your variables here
WITH vars AS (
  SELECT '2018-01-01' as from_date,
         '2018-05-01' as to_date
)

-- Then use them by pulling from vars with a SELECT clause
SELECT *
FROM   your_table 
WHERE  date_column BETWEEN
          CAST((SELECT from_date FROM vars) as date)
          AND
          CAST((SELECT to_date FROM vars) as date)

Atau bahkan kurang bertele-tele:

#standardSQL
-- Set your variables here
WITH vars AS (
  SELECT DATE '2018-01-01' as from_date,
         DATE '2018-05-01' as to_date
)
-- Then use them by pulling from vars with a SELECT clause
SELECT *
FROM your_table, vars 
WHERE date_column BETWEEN from_date AND to_date
