Hive CREATE TABLE LIKE另一个表集分区键

Question

我有table1没有分区键，我想创建一个table2，使用与table1相同的架构，但设置一列＆＃34; datestr＆ ＃34;作为分区键。如何编写CREATE TABLE LIKE查询来执行此操作？

table1:

datestr, userID, transaction, balance




table2 (set datestr as partition key):

datestr, userID, transaction, balance

Answer 1

CREATE TABLE LIKE DDL不支持设置分区

我相信你可以像这样执行CTAS查询

Create table table2 (userID INT, transaction STRING, balance DECIMAL) 
Partitioned by (datestr STRING) 
as 
select userID, transaction, balance, datestr 
From table1;

当然，相应地添加列类型
