Dear Adivi ,

Congratulations on choosing the most advanced  opensource database on earth.
You can expect all the support from the nice people residing here ;-)

yes postgresql 7.3.x  CAN
check
http://techdocs.postgresql.org/guides/SetReturningFunctions
for details.

I dont get this question very much, someone else might be
able to help u here.

You cannot have [out] parameters in term of MS TSQL word,
but your function could return a complex type, that will do a trick.
Still you cannot return a recordset and [out] params, but do you need
it?

If you need both, you can use a temp table...

Unfortunately I cannot tell you much about Postgres on Unix and client
on Windows, but all my test apps written on VB and PG running on Linux,
so this combination works and I think should not be much pain for you as
well.
Would be interesting to here real success story of happy marriage of
postgres and ADO.

thanks for the caution Maksim ,

    but i do need to have my database on PostGreSql running on a
unix/linux
box.
    and i just need to have the application on Windows + .Net

    i can use odbc.net or inherit the adapter

    do you still see any possibility of serious issues !?
    please do let me know if i am headed in the wrong direction

regards
-adivi

So I would tell you, before doing something ask yourself what is you
goal,
if you shop primary OS is MS Windows and client is
VB or .Net or more generally ADO 2.7.x you'll probably looking into
wrong direction,
because nothing works better with ADO then MS SQL Server.
I am not telling you that postgres will not suite you, that will if you
are
following certain pattern.
What is you goal?

thanks for the reply:

    but Functions can do return Cursor !
    can i parse them from a .Net application ?

    also i've found that PostGreSql 7.3 + can return recordset
    http://techdocs.postgresql.org/guides/SetReturningFunctions

please reply if i can parse , using a .Net application or any such fromt
end
application,
    a.> cursors returned by a PostGreSql function
    b.> recordset ( multiple rows and columns ) returned by a PostGreSql
function

Dear Adivi,

You may also have a look at pgAdmin3, PostgreSQL administration GUI for Win32,
GNU/Linux and FreeBSD. pgAdmin3 has very nice features to write server-side
code.

Daily snapshots can be downloaded from:
http://cvs.pgadmin.org/cgi-bin/viewcvs.cgi/*checkout*/pgadmin3/docs/en_US/snapshots.html

Also, if I read your email correctly, are you from India? We already have 21
languages in preparation. India, with 1,6 billion inhabitants by 2040, is one
of our main targets. If you would like to translate pgAdmin3 into Indi,
please refer to this documentation:

http://cvs.pgadmin.org/cgi-bin/viewcvs.cgi/*checkout*/pgadmin3/docs/en_US/translation_steps.html
http://cvs.pgadmin.org/cgi-bin/viewcvs.cgi/*checkout*/pgadmin3/docs/en_US/translation_guidelines.html
http://cvs.pgadmin.org/cgi-bin/viewcvs.cgi/*checkout*/pgadmin3/docs/en_US/translation_team.html
