-------------------------------------------------------------
Following up with OAK-4401 it looks like rep:excerpt(propertyName) and
rep:excerpt(.) are not meant to be used as columns in jcr-sql2 but to get an
excerpt based on a result row.
This is at least also the same behaviour as implemented in
[XPathToSQL2Converter.java|https://github.com/apache/jackrabbit-oak/blob/trunk/oak-core/src/main/java/org/apache/jackrabbit/oak/query/xpath/XPathToSQL2Converter.java]

> rep:excerpt selector broken as regression of OAK-6750

> Issue Type: Bug

> The change made here:
> https://github.com/apache/jackrabbit-oak/commit/00c94b71293abcae6d76bb162c3f55c7d09b702e#diff-d4bdf443c61f24b634f33aab607e2114
> breaks the logic in line 676:
> {{else if (oakPropertyName.equals(QueryConstants.REP_EXCERPT + "("))}}
> This statement doesn't make much sense considering a query like {{select
> \[rep:excerpt] from \[test:Page] as page where contains(\*, 'term\*')}} or
> even {{select \[rep:excerpt(text)] from \[test:Page] as page where
> contains(page.\[text], 'term\*')}}
