BQ 查询 - 在逗号后添加空格

Question

I am writing a query in BQ and it is returning a concatenated comma separated String with no whitespace. I want to add a whitespace after the comma.

All the things I have tried that work in other SQL queries as in CONCAT_WS, etc. are not working.

Query:

   CASE WHEN u2.reportsDown IS NULL THEN u1.reportsUp ELSE CONCAT(u1.reportsUp, ", ",   u2.reportsDown) END as accountLIST
   FROM ```

Result:
```12345,67890,09876,54321,102938,564738```

Desired Result:
```12345, 67890, 09876, 54321, 102938, 564738```

Even adding a _ after the comma is not doing anything. Not even the _ is showing up.

Does anyone know how I can get a whitespace after the comma in a BQ query?

Thank you!

Was able to use the REPLACE function in BQ to add the whitespace
