BigQuery uses re2 for regular expressions, and re2 does support flags.
BigQuery将re2用于正则表达式,而re2确实支持标志。
For example, to do a case insensitive match:
例如,要进行不区分大小写的匹配:
SELECT REGEXP_MATCH('TomatoPotato', r'TOpo')
false
SELECT REGEXP_MATCH('TomatoPotato', r'(?:TOpo)')
false
SELECT REGEXP_MATCH('TomatoPotato', r'(?i:TOpo)')
true
