Expressions to use for selecting specific columns

[Joseph]

Let's say I want to only extract the User Request column which is the first column (column name is "ref" in the database), normally in SQL I would use

SELECT ref FROM UserRequest

Any idea how to do the equivalent in OQL?

Thanks in advance

What's the exact use case? As when you export information, you can select which fields you want; but it's not possible with OQL itself.
