如何在 BigQuery 查询中转义双引号？

Question

I wanted to update the strings contain double quote character, so I searched using this BigQuery query

select phonenumber from database
where  phonenumber like '%\"%'

but got no result. Something like '%\\\\"%' didn't work too, but searched for \t character using '%\\\\t%' did work. I don't understand how to properly escape special characters in BigQuery. Please help

Answer 1

I don't think you need to escape the double quote. Doesn't this work?

select phonenumber from database where phonenumber like '%"%'

This is explained in the documentation :

Quoted strings enclosed by single ( ' ) quotes can contain unescaped double ( " ) quotes, as well as the inverse.

 "abc" "it's" 'it\'s' 'Title: "Boy"'
