Re: Return BLOB from Stored Procedure

[Charles Wilt <charles.wilt@xxxxxxxxx>]

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.
