蜂巢CREATE TABLE LIKE其他表集分區鍵

Question

我有沒有table1分區鍵，我想創建一個table2，用相同的模式table1，但設置一列「datestr」作爲分區鍵。我如何編寫CREATE TABLE LIKE查詢來執行此操作？

table1: 

datestr, userID, transaction, balance 




table2 (set datestr as partition key): 

datestr, userID, transaction, balance 

Answer 1

的CREATE TABLE LIKE DDL不支持設置分區

我相信你可以執行CTAS查詢像這樣

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

當然添加相應的列類型
