RE: DISPLAY_JOURNAL and ENTRY_DATA parsing using pure SQL

Here is a Scott Klement UDTF from RPG.

Yours may be a lot easier since you will always be returning a single row.

Can you convert your RPG into a UDTF? If so, you should be able to easily incorporate that into a view.

Subject: DISPLAY_JOURNAL and ENTRY_DATA parsing using pure SQL

I developed a hybrid RPG and SQL program to query the DISPLAY_JOURNAL SQL UDTF from IBM, which if you use it, you know that the ENTRY_DATA column comes in as an incomprehensible BLOB. I've used RPG to overlay this BLOB onto a data structure and written this out to a file with the journalled file structure pre-built to be able to view this data. What I'm wondering is, if there is an SQL way to dump this data onto a file and/or structure so that I might be able to build this process as a view, rather than an outfile to further reduce unnecessary file I/O. If it were a view, then I imagine that the program would just create the view, in say QTEMP, and then I could query the fields as desired before the data was actually written anywhere.

The column I'm trying to parse is currently coded as follows:
cast(entry_data as char(5000) for bit data)
