I have this code:
SELECT
ZONE_NAME,
ORG_ID,
ORG_SHORT_NAME,
XMSSN_USE
FROM TABLEZ
;
UPDATE TABLEZ
SET TABLEZ.BILL_CYCLE = '1-DEC-2020 4' WHERE (SELECT TABLEZ.XMSSN_USE WHERE TABLEZ.XMSSN_USE=224)
But it doesn't seem to execute. What could be the problem?
You have 2 different query sentences. You should use ; after first query and then write the update query.
Also you need to use some field on the where clause, your where is empty.

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.
