Why has the capitalization of column header in my Sigma query result changed? : Stripe: Help & Support

Why has the capitalization of column header in my Sigma query result changed?

As of September 3rd 2020, Sigma supports queries using Prestosql v334 SQL syntax. As a part of this change, capitalization of column header is preserved from original column name in subqueries.

For example:

SELECT * FROM ( SELECT AmoUnT FROM charges )

Old behavior:

amount
1.23

New behavior:

AmoUnT
1.23
