BINARY存储在记录中,不想BLOB单独存储,可以在BINARY中包含任意字节序列,会原样存储,不会被解析成数字或者字符。 Complex Data Types Hive还支持一些关系型数据库不支持的复合数据类型。 复合数据类型由primitive data types和other complex data types构成,如下: ARRAY - 相同类型的元素构成的序列,从0开始索引,与Java中...
我们可以把String,TimeStamp值转换成Date类型: Miscellaneous Types Hive还提供两种primitive data types,BOOLEAN和BINARY。和Java的Boolean相似,BOOLEAN只存储true或者false。 BINARY是字节数组,和很多关系型数据库的VARBINARY相似。BINARY存储在记录中,不想BLOB单独存储,可以在BINARY中包含任意字节序列,会原样存储,不会被解析...
