Rong Rong commented on FLINK-7342:
----------------------------------
Seems like {{SIMILAR TO}} was already supported in Flink, should we close this
ticket or is there any additional features we need to support using LIKE
operator?
> Add support for Regular Expression Operators (RLIKE)
> -----------------------------------------------------
>
> Key: FLINK-7342
> URL: https://issues.apache.org/jira/browse/FLINK-7342
> Project: Flink
> Issue Type: New Feature
> Components: Table API & SQL
> Reporter: sunjincheng
> Assignee: sunjincheng
> Priority: Major
>
> Currently Regular Expression Operators (RLIKE) are not supported. e.g.:
> {code}
> select * from emps name rlike '^(K|G|W)'
> {code}
> we'll get Error:
> {code}
> Error: Error while executing SQL "select * from emps name rlike '^(K|G|W)'":
> parse failed: Encountered "rlike" at line 1, column 25.
> {code}
> So, after https://issues.apache.org/jira/browse/CALCITE-1918 fixed. I want
> add RLIKE supported in flink (TableAPI and SQL).
