Astyanax是否支持使用CQL3的预处理语句进行“insert into”操作? 我使用最新的Astyanax库1.56.24和Cassandra 1.2.1。当我尝试使用CQL3执行预处理语句时:
keyspace.prepareQuery(conn.CF_CONTACTS)
.withCql("INSERT INTO contacts (a, b) VALUES (?, ?);")
.asPreparedStatement()
.withStringValue("123")
.withStringValue("456")
.execute();;
I get the following exception:
Caused by: InvalidRequestException(why:Cannot execute/prepare CQL2 statement since the CQL has been set to CQL3(This might mean your client hasn't been upgraded correctly to use the new CQL3 methods introduced in Cassandra 1.2+).)
