The Apache Derby project is pleased to announce feature release 10.17.1.0.
Apache Derby is a sub-project of the Apache DB project. Derby is a pure
Java relational database engine which conforms to the ISO/ANSI SQL and
JDBC standards. Derby aims to be easy for developers and end-users to
work
Build 18-ea+23-1525 has introduced another hurdle for applications which
use the SecurityManager. In order to install a SecurityManager, you now
have to set -Djava.security.manager=allow on the boot command line. This
property cannot be set programatically, unlike the other system
properties
Trigger transition tables can only be used for row-scoped triggers (FOR
EACH ROW triggers). They cannot be used for statement-scoped triggers (FOR
EACH STATEMENT triggers). I suppose that you could create a row-scoped
trigger which populates a scratch table from the values of the transition
table.
Thanks, Alan.

I am puzzled by the behavior of column identifiers in Spark SQL. I don't
find any guidance in the "Spark SQL and DataFrame Guide" at
http://spark.apache.org/docs/latest/sql-programming-guide.html. I am seeing
odd behavior related to case-sensitivity and to delimited (quoted)
identifiers.
I see that lib_managed/jars holds these old Derby versions:
lib_managed/jars/derby-10.10.1.1.jar
lib_managed/jars/derby-10.10.2.0.jar
The Derby 10.10 release family supports some ancient JVMs: Java SE 5 and

For what it's worth, I get the expected result that "filter" behaves like
"group by" when I run the same experiment against a DataFrame which was
loaded from a relational store:
