Re: Return BLOB from Stored Procedure

Thanks Elvis,

You're thinking was along mine, but a quick test:

d myRs ds qualified dim(10)
d fld1 10a
d myBlob SQLTYPE(BLOB:32766)


/free
exec sql set result sets array :myRS for 1 rows;

*INLR = *ON;
return;
/end-free


Doesn't compile. Once I added the BLOB field, I get a
SQL5011 Position 58 Host structure array MYRS not defined or not usable.

I might look at doing it from C. I suspect I might have better luck.

I've never done this in an HLL, but it might be possible.

Here's a link to one of Scott's articles demonstrating BLOB field
declaration within RPG:

And here's a link to documentation for SET RESULT SETS ARRAY
yourLocalStructure FOR 1 ROWS type statement:

I think it's worth a test, if it compiles :)

Subject: Return BLOB from Stored Procedure

All,

I've got a .PDF file in the IFS I want to return as a BLOB column in a
result set from a stored procedure.

Stored procedure can be written in SQL or RPG, it doesn't matter.
(Thus the cross post, sorry David :)

The stored procedure will return just a single row.

Can I do this directly without loading the BLOB column into a temporary
table?

Links and/or examples appreciated.


Thanks!
Charles
