I have a SQL Query, which returns a table with one column.

The returned data may be duplicate. for example, my query may be something like:

SELECT item FROM myTable WHERE something = 3

and the returned data may be something like this:

item
-----
2
1
4
5
1
9
5

My Question is, How to remove duplicated items from my query?

I mean, I want to get these results:

item
-----
2
1
4
5
9

Please note that I don’t want to change or delete any rows in table. I just want to remove duplicates in that query.

How to do that?

Answer 1
