How can I remove the duplicate rows? I have joined two tables now I'm getting duplicate data.
In addition to previous comments, a little bit more complex answer will be construction with PARTITION and ROW_NUMBER
select * from (select *, row_number() over (partition by <duplicate_field> order by <duplicate_field>) as rn from <table>) where rn=1

Im Expecting some functionality like below,
select ARRAY((select distinct Somecolumn from Dataset.tablename) )
select STRUCT((select distinct Somecolumn from Dataset.tablename) )
You can use array_agg function to generate an array, but generating struct is not possible.
select ARRAY_AGG(distinct Somecolumn) from Dataset.tablename

From the above table, I want to remove the rows that have the duplicate CODE column. Out of the duplicate rows, the row with the smallest ID_CHECK should be retained.
Output:
If I understand correctly, this should be your SQL query:
Select Names, Code, ID_CHECK
FROM
(
Select Names, Code, ID_CHECK,
ROW_NUMBER() OVER(Partition by Name,Code Order By ID_CHECK) as rnk
FROM table
)tmp
WHERE tmp.rnk=1;
Let me know if this works.
