             Summary: Add oracle regexp_like function in phoenix
                 Key: PHOENIX-3215
                 URL: https://issues.apache.org/jira/browse/PHOENIX-3215
             Project: Phoenix
          Issue Type: Improvement
            Reporter: Loknath Priyatham Teja Singamsetty 
            Assignee: Loknath Priyatham Teja Singamsetty 
            Priority: Minor


We have regexp_substr today which returns a substring of a string by applying a 
regular expression start from the offset of a one-based position.

However, when using query builder frameworks like JOOQ code generators that 
generates java code from database and build type safe sql queries out of box, 
lack of regexp_like syntax is making developers to take work arounds to build 
the equivalent queries.


Hard coding Query for regexp_substr as JOOQ does not support it:

{quote}
regex = regex + " AND regexp_substr("+ 
TestResultEntity.Column.BASELINE_MESSAGE.getName() +", ?)" + matching;
{quote}


Here is the oracle documentation for regexp_like
