>                 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

> 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'"
