Subject [jira] [Created] (CASSANDRA-2663) JDBC driver for CQL works only with Strings
Date Wed, 18 May 2011 12:31:47 GMT
JDBC driver for CQL works only with Strings

                 Key: CASSANDRA-2663
             Project: Cassandra
          Issue Type: Bug
          Components: API
    Affects Versions: 0.8.0 beta 2
         Environment: It happens to JDBC driver for both: 0.8.0 beta version and 0.8.0-rc1
            Reporter: Roman Kuzmin

Line 141:

String stringParam = makeCqlString(type.toString(param));

It crashes with ClassCastException for all parameters that are not Strings. It is because,
when the method applyDualBindings is called from makeUpdate it ALWAYS get one and the same
"type" as parameter. In fact it is a comparator of columnfamily itself.

In my case it is UTF8Type. And UTF8Type.toString() method expects only Strings.

I think it must be column-dependent.
