如何使用CQL 3.0与JDBC驱动程序或Hector [英] How to use CQL 3.0 with JDBC drivers or Hector
问题描述
我使用cassandra 1.1.1。但是,每当我使用复合键创建列族时,我会收到以下错误:
I am using cassandra 1.1.1. But, whenever I create a column family with composite keys, I will get an error as below,
java.sql.SQLSyntaxErrorException: line 1:117 mismatched input ')' expecting EOF
at org.apache.cassandra.cql.jdbc.CassandraStatement.
doExecute(CassandraStatement.java:180)
at org.apache.cassandra.cql.jdbc.CassandraStatement.executeUpdate(
CassandraStatement.java:237)
at jdbc.cassandra.JdbcCassandra.main(JdbcCassandra.java:59)
我的查询是 CREATE TABLE sblocks(block_id uuid,subblock_id uuid,data blob,PRIMARY KEY(block_id,subblock_id));
一些身体能帮助我吗? / p>

推荐答案
您暗示您的问题标题中的答案:您的连接可能实际上不使用CQL版本3.使用版本3必须明确请求语法。
You alluded to the answer in your question title: your connection probably is not actually using CQL version 3. Use of the version 3 syntax has to be explicitly requested.
最新版本的JDBC驱动程序尚不支持请求CQL 3.然而,'trunk'分支中的版本确实,你不介意生活在JDBC驱动程序边缘。
The latest version of the JDBC driver does not yet support requesting CQL 3. The version in the 'trunk' branch does, though, if you don't mind living on the JDBC driver edge.
