Subject [jira] [Created] (CASSANDRA-2939) CQL regex to match column family in query
Date Fri, 22 Jul 2011 19:34:58 GMT
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


In the file cursor.py (https://svn.apache.org/repos/asf/cassandra/drivers/py/cql/cursor.py)

Line 37: _cfamily_re = re.compile("\s*SELECT\s+.+\s+FROM\s+[\']?(\w+)", re.I | re.M)

The Regex will improperly match anything after the word  'from' even if it is in the WHERE
clause

I believe the fix is:

_cfamily_re = re.compile("\s*SELECT\s+.+?\s+FROM\s+[\']?(\w+)", re.I | re.M)

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'"
