I'm not an expert on exactly how the internals of this work but here is
what I know about the subject.

There are two ways to give columns names in SQL (which match to some aspect
of DDS that I know nothing about).  Here are two examples;

LABEL ON COLUMN CollectionName.tableName (columnName text is 'descriptive
entry')

COMMENT ON COLUMN CollectionName.tableName (columnName IS 'descriptive
entry')

The Native JDBC driver can only see entries from teh COMMENT ON command.  I
don't know exactly where the LABEL ON entries end up, but they don't get
returned from the database through the CLI.  I believe the Toolbox JDBC
driver can see either one.

All,

We have column labels defined for the columns in a DB/400 table. When
running a query from STRSQL we see the nice long descriptions of the
columns. I have not been able to receive the same information using JDBC
ResultSet MetaData.

Is it possible to retrieve this data?
