need to define subfield instead of substring for sql function display_journal

qsys2.display_journal returns as a blob a file record format (say: a structure) that include all types of subfields. today, we only can extract CHAR fields with the substring function. example: cast(cast(substring(entry_data, 155, 18) as char(18) for bit data) as char(18) ccsid 37) as ADRES5, hex(cast(substring(entry_data, 173, 2) as char(2) for bit data) ) as ADOLEN, out of the fact the syntax is difficult, the substring cannot return an integer. I would like to use a subfield function instead of substring idea: some sort of pointer logic cast(subfield(entry_data, 155, 18) as char(18) ccsid 37) as ADRES5, cast(subfield(entry_data, 173, 2) as smallint ) as ADOLEN, I'd like to use display_journal of qsys2, sql service is easier than dspjrn. because integration via sql is the prefered way of many available reporting tools. sometimes the only way.

    IBM believes that the request described has been solved with the addition of the INTERPRET built-in function.

    This was delivered for IBM i 7.4 with DB PTF Group SF99704 Level 7 and IBM i 7.3 with DB PTF Group SF99703 Level 18.

    Take a look at the INTERPRET function. I think it does what you want.
