Takeshi Yamamuro updated SPARK-27987:
-------------------------------------
Parent Issue: SPARK-30375 (was: SPARK-27764)
> Support POSIX Regular Expressions
> ---------------------------------
>
> Key: SPARK-27987
> URL: https://issues.apache.org/jira/browse/SPARK-27987
> Project: Spark
> Issue Type: Sub-task
> Components: SQL
> Affects Versions: 3.0.0
> Reporter: Yuming Wang
> Priority: Major
>
> POSIX regular expressions provide a more powerful means for pattern matching
> than the LIKE and SIMILAR TO operators. Many Unix tools such as egrep, sed,
> or awk use a pattern matching language that is similar to the one described
> here.
> ||Operator||Description||Example||
> |{{~}}|Matches regular expression, case sensitive|{{'thomas' ~ '.*thomas.*'}}|
> |{{~*}}|Matches regular expression, case insensitive|{{'thomas' ~*
> '.*Thomas.*'}}|
> |{{!~}}|Does not match regular expression, case sensitive|{{'thomas' !~
> '.*Thomas.*'}}|
> |{{!~*}}|Does not match regular expression, case insensitive|{{'thomas' !~*
> '.*vadim.*'}}|
