对于具有相同参数值的相同分区的配置单元中的多个插入，插入覆盖

Question

Hi Guys,

So I am trying to do multiple inserts and i am successfully able to do it but if there are two queries which have same partition and static value assigned it gives me the following error :15:02:22 [EXPLAIN - 0 row(s), 0.000 secs] [Error Code: 10087, SQL State: 42000] Error while compiling statement: FAILED: SemanticException [Error 10087]: The same output cannot be present multiple times: table_name@id=0
here first insert happens successfully but because second insert has the same value assigned for id which is 0 ..it gives the above error ..please let me know a workaround.Thanks :)

FROM (  
      Select * from Table_Name
     )Query
INSERT OVERWRITE TABLE Table_Name PARTITION(id=0)
 select column1,column2,column3
 GROUP BY column1,column2,column1

INSERT OVERWRITE TABLE Table_Name PARTITION(id=0) 
   select column1,count(*) as column2

Instead of multiple inserts, you can just do one insert with a union of the two queries.

FROM (  
      Select * from Table_Name
     )Query
INSERT OVERWRITE TABLE Table_Name PARTITION(id=0)
  select <query 1>
  UNION ALL
  select <query 2>
