Java “线程中的异常”；“主要”；com.datastax.driver.core.exceptions.InvalidQueryException:主键中引用的未知定义

我正在尝试使用JavaAPI在Cassandra中创建表

此查询工作正常，并创建了表

String query = "CREATE TABLE IF NOT EXISTS TopQuery1(term text , "
            +"year text , "
            +"month text , "
            +"day text , "
            +"hour text , "
            +"count counter,"
            +"PRIMARY KEY (\"term\", \"year\", \"month\", \"day\", \"hour\" ));";

但是当我执行下面的查询时，它抛出了一个错误

String query = "CREATE TABLE IF NOT EXISTS TopQuery2(term text , "
            +"year text , "
            +"month text , "
            +"day text , "
            +"hour text , "
            +"dayOfYear int , "
            +"weekOfYear int , "
            +"ProductCount int , "
            +"count counter,"
            +"PRIMARY KEY (\"term\", \"year\", \"month\", \"day\", \"hour\", \"dayOfYear\", \"weekOfYear\", \"ProductCount\"));";      

这就是错误：

我真的不明白我遗漏了什么。默认情况下，列名不区分大小写，除非用双引号括起来

定义列时不使用引号，因此称为

dayofyear

：

+"dayOfYear int , "

+"PRIMARY KEY (... \"dayOfYear\" ...)";

但在主键定义中使用引号，因此它要查找一个名为

dayOfYear

：

+"dayOfYear int , "

+"PRIMARY KEY (... \"dayOfYear\" ...)";

可以在任何地方使用引号，也可以不使用引号（取决于区分大小写是否重要）
