BigQuery 标准 SQL SELECT 行 WHERE 字段包含来自另一个表字段的单词

Question

I have 2 tables in BigQuery. VIDEOS table contains video names and tags. CREATORS table contains information about video creators. The VIDEOS.tags field contains comma separated quoted strings.

I need to select all the videos that were tagged with names in the CREATORS table with results looks like this:

Title 1, Creator 1
Title 2, Creator 2
Title 3, Creator 2
Title 4, Creator 3
Title 5, Creator 3
...

But what I have below does not return any results in BigQuery.

SELECT
    B.name AS Title,
    C.creator_name AS Creator
FROM `project.database.VIDEOS` AS B, `project.database.CREATORS` AS C
WHERE B.tags LIKE CONCAT('%"', C.creator_name ,'"%')

Answer 1

在这种情况下，通常是因为情况不同 - 尝试

WHERE LOWER(B.tags) LIKE CONCAT('%"', LOWER(C.creator_name) ,'"%')

Answer 2

I think you want it the other way around: The tag has to look like the name. Let me know

SELECT
    B.name AS Title,
    C.creator_name AS Creator
FROM `project.database.VIDEOS` AS B, `project.database.CREATORS` AS C
WHERE C.creator_name LIKE CONCAT('%"', B.tags ,'"%')
