> CQL regex to match column family in query
> -----------------------------------------
>
> Key: CASSANDRA-2939
> URL: https://issues.apache.org/jira/browse/CASSANDRA-2939
> Project: Cassandra
> Issue Type: Bug
> Components: Drivers
> Environment: Python CQL
> Reporter: Blake Visin
> Assignee: Blake Visin
> Priority: Minor
> Labels: CQL, python
> Attachments: 2939-test.txt, 2939.txt

> In the file cursor.py
> (https://svn.apache.org/repos/asf/cassandra/drivers/py/cql/cursor.py)
> {code}Line 37: _cfamily_re = re.compile("\s*SELECT\s+.+\s+FROM\s+[\']?(\w+)",
> re.I | re.M){code}
> The Regex will improperly match anything after the word 'from' even if it is
> in the WHERE clause
> I believe the fix is:
> {code}_cfamily_re = re.compile("\s*SELECT\s+.+?\s+FROM\s+[\']?(\w+)", re.I |
> re.M){code}
> Added the ? so the regex is not so greedy
> use this query to reproduce the results:
> SELECT key FROM column_family WHERE key = 'break from chores'"
