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.

I need to remove repeated records in search result. I have 3 columns (id, worklevel & umobile).
It looks like below:

Try using DISTINCT

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

i got this table, and i want to divide all the values on one of the columns except one.
I havent wrote any code about it just looking for an explanation on how to do it, if anyone could help out would appreciate.
In order to modify the content of one column in all rows except one, you can use the following query:
UPDATE tablename SET columName = columnName / 42 WHERE rowId !=42;
WHERE contains the condition that has to evaluate to true, in order for the update to take effect. My example modifies all rows except for those whose rowId column contains the value 42.
