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

As of September 3rd 2020, Stripe 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
```
