Bug ?? in Set Expressions Builder in QS Nov 2018?

All,

There was an update to the Set Analysis syntax Quotes in Set Analysis‌ (Sep 2017)

Today, in QS Cloud (Nov 2018) there is a SET expression builder that got released.

I believe there is a minor flaw in it :

Above expression was built using the Set Analysis Builder and it wrapped the year value 2013 in single quotes. As far as I'm aware, the wrapping in quotes should be done if the value is a string literal. So it should be Year={2013}.

Or am I wrong?

Single quotes should denote literals, i.e. explicit field values.

No, it works properly. Whether you should use

{<Year={2014}>} ,

{<Year={'2014'}>} or

{<Year={"2014"}>}

is a matter of taste. All three will work for this field value. Single quotes denote explicit field values, just as Dilip points out.

No quotes will cause problems if the field value contains spaces. Double quotes will cause problems if there are two field values that only differ in the upper/lower case. So, we chose to wrap all field values in single quotes, because then it always works.
