Re: [GENERAL] different results for large objects

[c k <shreeseva.learning@xxxxxxxxx>]

Yes, the problem is with PGAdmin and ODBC connection to MS access.
The function (given is first mail) is giving same results i.e. only IDs not the actual data from PGAdmin and ODBC.
But for following query PGAdmin gives again only IDs, but MS Access through ODBC gives the actual binary data.

select docimages.* from docimages where docimages.accobjecttype=9 ORDER BY docimages.docimagename;

So I think ODBc is making some magic here for showing large object data. If this is correct how can I retrieve the actual binary data from a function/single statement as above?

Thanks,

There is no server-side behavior that would cause that query to show you
a large object's contents instead of its identifying number.  I suppose
that you have some client-side code that does something magic when it
sees a result column of type "lo", and that for some reason this code
is not successfully recognizing the case where the column is coming out
of a function.  Since you've shown us neither the troublesome query
nor the client-side code, it's hard to speculate further than that.
