问题
I have installed datastax ODBC driver for cassndra and also i have created keyspace and some tables using cql 3. But ODBC driver is not showing up those tables. Also in odbc documentation i read that the driver does not currently support version 3.0 of the Cassandra Query Language (CQL3) and the driver will not recognize keyspaces and column families that are defined with CQL 3. So in order to use cql 2 i am using following command which is suggested in driver documentation:
...\cqlsh” -2
But this is giving an error saying "cqlsh: error: no such option: -2"
Can anybody help me out with this?
回答1:
cql2 is deprecated and was removed from cslqh in Cassandra 2.0. It will be removed from the server as well in 3.0.
I do not know when cql3 support will be added to the ODBC driver.
回答2:
The documentation is not correct regarding how to start cqlsh using a previous spec/version...you need to use --cqlversion instead of -2 (see notes below). However, as mentioned in jbellis' answer cql2 support has been removed from later versions of cassandra.
