In fact, experimentation seems to suggest that the breaking point is a
length of 32K+.
This seems to match the VARCHAR and LONG VARCHAR specifications:
* https://db.apache.org/derby/docs/10.16/ref/rrefsqlj41207.html
* https://db.apache.org/derby/docs/10.16/ref/rrefsqlj15147.html
This happens to be the string literal in your INSERT statement. If you
want to insert more than 32K in your CLOB column you would need to use
the JDBC interfaces:
*
https://docs.oracle.com/en/java/javase/17/docs/api/java.sql/java/sql/PreparedStatement.html#setCharacterStream(int,java.io.Reader,int)
*
https://docs.oracle.com/en/java/javase/17/docs/api/java.sql/java/sql/PreparedStatement.html#setClob(int,java.io.Reader,long)
and for reading:
*
https://docs.oracle.com/en/java/javase/17/docs/api/java.sql/java/sql/ResultSet.html#getCharacterStream(int)

According to what I'm reading, a CLOB should easily hold more than the
