BigQuery SELECT NULL AS“some_name”：意外的字符串文字

Question

I would like to set a string column as NULL in BigQuery with the query

SELECT NULL AS "h3-2"
 FROM `sometable` LIMIT 10

But I get the error Syntax error: Unexpected string literal "h3-2" at [1:16]

How do I set a column as NULL?

Answer 1

The problem was indeed using a string literal.. I added the quotes because h3-2 also wasn't working but instead I had to do

SELECT NULL AS h3_2
 FROM `sometable` LIMIT 10

to get it to work
