Bigquery选择不同的值

Question

如何在Google Bigquery中选择不同的值？

查询:

SELECT DISTINCT cc_info
FROM user
WHERE date = ?

谢谢!

Answer 1

SELECT cc_info
FROM user
WHERE date = ?
GROUP BY cc_info

Answer 2

尝试使用group by

SELECT cc_info
FROM user
WHERE date = ?
group by cc_info

Answer 3

只需使用分组依据，

SELECT cc_info
FROM user
WHERE date = ?
GROUP BY cc_info

如果您想使用DISTINCT值进行计数，则可以使用，

SELECT COUNT(DISTINCT cc_info)
FROM user
WHERE date = ?
