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'"
