Re: Blob trouble !
- Hi Wynand,
Magic 9.4 SP8 can call Oracle 9 stored procedures and pass Blob
values in and receive Blob values back.
My guess is that your Magic Blob field is defined as a LONG RAW in
Oracle. If that is indeed the case, then converting the field in the
Oracle table from LONG RAW to Oracle's BLOB type should solve your
problem (assuming your Oracle stored proc and your Magic direct sql
task are OK).
Note that Magic V9 still uses Oracle's LONG RAW as the default for
Magic Blob fields (for Oracle 7 legacy purposes), but that
Oracle's 'newer' BLOB attribute (since Oracle 8) is supported by
Magic V9 as well. I suggest you create any new tables with Oracle
tools, use LOBs (BLOB, CLOB, NCLOB, BFILE) instead of LONG RAWs and
use 'Get Def' in Magic as required.
Hope this helps,
