BTW, I will try to implement reading BLOB fields
within a few weeks. There only is a small
problem with that at the moment: I need to
implement in TODBCConnection the function
function CreateBlobStream(Field:TField; Mode:TBlobStreamMode):TStream;
However, I need the TSQLHandle here (for the
ODBC API call), not the TSQLConnection, where it
is a method of. I think the Handle should be
passed as an additional parameter. Or is there
some way to (correctly) get the TSQLHandle from the Field parameter?
Based on my experience and lot of years "in the
field" I'd dare to say that TIMESTAMP is most
used than BLOB and GRAPHICS. At least if we are
speaking about business applications(like banks, credit card operators, etc)
Another thought on the problems Arí has with
update queries and TODBCConnection: as I need
only read access, I never implemented UpdateIndexDefs; might that be required?
UpdateIndexDefs? What is the function of such
method? Since data base manager ever keep the
index(es) up-to-date and it has the index(es)
description in its areas, I can't imagine...
I would like to remember that it's so important
that DB2 keep the TIMESTAMP in the format with 6
digits of fraction of second. BTW I thing and
insist that a return of string [26] will be more
easy(I think) and clear. People can do the
conversions in the application program.
But I have no skill to discuss this with the Lazarus/FPC developers.
Best regards
Arí
