Mikko Koppanen commented on CASSANDRA-3025:
-------------------------------------------
Hello,
if I have following column families inside a keyspace:
CREATE TABLE cf1 (my_key text PRIMARY KEY, test int)
CREATE TABLE cf2 (my_key text PRIMARY KEY, test text)
where each one of them have the same column with different type. There doesn't
seem to be any information in the CqlResult telling me which column family the
columns belong to. Does this mean that I should parse each SELECT query and the
column family from there?
It looks that key_alias is unique within column family as well, so there is no
way of knowing that "my_key" is ascii. This is slightly problematic when
marshaling the values to correct PHP types.

> Hello,
> attached is the initial version of the PDO driver for Cassandra CQL language.
> This is a native PHP extension written in what I would call a combination of
> C and C++, due to PHP being C. The thrift API used is the C++.
> The API looks roughly following:
> {code}
> <?php
> $db = new PDO('cassandra:host=127.0.0.1;port=9160');
> $db->exec ("CREATE KEYSPACE mytest with strategy_class = 'SimpleStrategy' and
> strategy_options:replication_factor=1;");
> $db->exec ("USE mytest");
> $db->exec ("CREATE COLUMNFAMILY users (
> my_key varchar PRIMARY KEY,
> full_name varchar );");
>
> $stmt = $db->prepare ("INSERT INTO users (my_key, full_name) VALUES (:key,
> :full_name);");
> $stmt->execute (array (':key' => 'mikko', ':full_name' => 'Mikko K' ));
> {code}
> Currently prepared statements are emulated on the client side but I
> understand that there is a plan to add prepared statements to Cassandra CQL
> API as well. I will add this feature in to the extension as soon as they are
> implemented.
> Additional documentation can be found in github
> https://github.com/mkoppanen/php-pdo_cassandra, in the form of rendered
> MarkDown file. Tests are currently not included in the package file and they
> can be found in the github for now as well.
> I have created documentation in docbook format as well, but have not yet
> rendered it.
> Comments and feedback are welcome.
> Thanks,
> Mikko
