Re: Move SQL Blob field (PDF) to IFS folder

Using RPG to Extract Binary Files from BLOB Columns

So now the binary data is safely tucked away in the BLOB. What happens in
the future when you need to access the data in the BLOB? You simply write
the file back out of the IFS. Just use the appropriate file options to
instruct the program to go the other direction. The following RPG example
does just that.

*D MYFILE S SQLTYPE(BLOB_FILE) *

*D SQL_FILE_OVERWRITE... *

*D c const(16) *

*/free *

* myfile_fo = SQL_FILE_OVERWRITE; *

* myfile_name = '/home/2011_Data/Financials_2011.xls'; *

* myfile_nl = %len(%trimr(myfile_name)); *

* exec SQL *

* SELECT docblob *

* INTO :myfile *

* FROM QGPL/DOCREPOS *

* WHERE DocTitle = '2011 Financials Spreadsheet'; *

* return; *

*/end-free *

*
*

Ok, you have BLOB columns, character columns, numeric columns, etc. What
is another type? Datalink? Now, I've never used them, but is there some
way to move a blob column to a data link column?

Subject: Move SQL Blob field (PDF) to IFS folder - How?
Sent by: midrange-l-bounces@xxxxxxxxxxxx

Am writing an external stored procedure (rpgle) to read a bunch of db2 sql
tables populated by a web process. Part of what the procedure is being
asked to do is move a pdf, which is stored as a blob in one of the tables,
onto a folder so it can be processed by Content Manager (our imaging
system). The Content Manager guys claim they cannot read the blob or do
anything with it (the api wants a folder). The web guys (Java & WAS) can
and have dropped all sorts of objects on the IFS, but prefer that the
stored procedure does it in this application.

I've searched this list and the internet in general and don't know where
to begin. There's little Java application code running on the iSeries so
a Java solution would be a maintenance issue. I'd appreciate any help.

TIA.

Jack
