同1.2中的本地导入和1.3中的 hdfs 导入类似,只是新增的关键字 overwrite 会将表中已有的数据进行覆盖操作。 1.5 查询导入 命令: 代码语言:javascript 代码运行次数:0 复制 Cloud Studio代码运行 create table[目标table_name]asselect*from[已存在table_name]; ...
insertoverwritetableload_data_partitionpartitionselectname,agefromload_data_local; 这种方式要注意目标表的字段必须和select查询语句字段的顺序和类型一致,特别是分区字段的类型要一致,否则会报错。 一张表有两个以上的分区字段,如果同时使用静态分区和动态分区导入数据,静态分区字段必须写在动态分区字段之前。
