 [Fwd: MS SQL compatible functions]

Hi everyone,

Dean here seems to be converting to PostgreSQL from MS SQL Server, and I
have *no* idea how to help him out.

He's not on the list, so if anyone's got suggestions, please remember to
keep him in the To/CC list.

:-)

Regards and best wishes,

Justin Clift

Dear Justin,
        My name is Dean Lu, I am working in a SI company in Taiwan, we are
going to change our products to support the PostgreSQL and drop the MS
SQL away, but I got some problems with the functions compatibility
between MS and pgSQL. Could you please give me some suggestions or tell
me where can I get the functions from Internet. It will be better if
those functions are written in C language. Thank you very much.

Best Regards'
Dean Lu

This is something that would be wonderful to have, a mapping of PostgreSQL functions to MSSQL Server functions.  In fact, I have been fantasizing about a compatibility module that would allow SQL Server applications to think they were talking to MSSQL Server when they were really talking to PG.  That is a huge job, but my how many more people would convert!

In the meantime, you will have to dump schema, twiddle them to meet PosgtreSQL requirements, and run them to re-create your db.  Your app will have to be re-written to some degree as well.

I think that kind of effort can be spent inceasing PG's capabilities.
What percentage of people who have MS are going to shift to PG.
The MS customer base is usually not the Linux/PG/GNU type. So
who are we trying to please. Those who buy MS are buying it for
commercial, finnancial, staffing and all the bean counting reasons.
Those decisions are made by non-techies. So now you going to
present to some IT Director who used to answer phones, your adapter
layer. And the first question you'll get is "So does that mean I can still
call my 800-microsoft-help-me for support". The second one is what is
Linux?

Let them be....

I dunno... you could also get the type of people that have built (or
inherited) a pre-existing application written in Oracle/SQLServer/etc that
no longer want to pay the license fees and would like to switch to
PostgreSQL, but aren't looking (or don't have the time right now) to
convert their entire application... having that abstraction layer makes it
that much easier for them to make the switch...

Yes.  No question about it.  Our biggest problem is that it lacks
_e{*filter*}ment_. :-)

Or it lacks priority.....on another thread a caller is asking for Distributed
PG
so he can install 20 linux boxes instead of an IBM 390 or Sun E10k

PG and Ingress have always been more popular in the academic world, why
not channel our energy in that area. Just imagine, a good distributed OS
(linux),
a good distributed DB (DPG) and a good distributed HTTP (apache, soap) and
we have lift off.

No question is is important.  It actually isn't the lack of e{*filter*}ment
which is the problem, it is really the lack of challenge and the fact it
is tedious to mimick another database.

 [Fwd: MS SQL compatible functions]
Dear all,

    Thanks for all of your advices and replied messages.
    I've start to study how to write a function in pgSQL, not only for my company or myself.
also not for please anyone. That is only what I am going to do, I'll try it.
     In Taiwan, most of the schools teach about MS series. So, we don't have the chance to touch
Linux as well, or I may say  " We didn't smell it when we were students." I learnt Linux since
8 months ago, and meanwhile I found that's what I were looking for.    
     MS is a very big company and a very variant software's provider, they spent lots of money on
marketing and localization for expanding their customer base. We can't ignore what they done
successfully lock on their customers. So, I won't blame or hate anyone who were making
decision to buy MS stuff.
     My company is a very small and young SI company, fortunately my boss is an open guy,
he agrees me that I am going to try to change the DB we used originally. In commercial
thinking, you may say that what I am doing is just wanted to keeping down the product cost.
But I have more expectancy on it.    
     "Linux", I can not make any definition on it cause I am just a beginner in this area, but if
by the rights of  free speaking, I may say Linux is an open spirit, we have no enemy here in Linux.
No fights, no hates, no self conceit, no self reliant. Thus, I am not talking about business, I am
talking about we should make more people know the pgSQL is a fantasy DB. If some of SI
companies can join the pgSQL group. isn't it wonderful? If we build a freeway or a bridge between
them and pgSQL, isn't it wonderful?
     I'd like to be one of the developers of pgSQL, but I know I am not qualify to do so, still I'll learn,
and hope I will be the one. My English is very poor but I've try so hard to read all the resources from
internet, and I need more resources about writing functions in C language, that's why I am here
and looking for some advices and helps from you masters.
    Thanks for your help again.

Best Regards'
Dean Lu

Hi Justin,

Just saw this on the newsgroup.

I think it would be interesting to do some gap analysis (apologies for the
management talk) that identified what could be done in MSSql server that
cannot be done in postgres and use that to:

a:    provide functional comparison material to allow people to make a more
informed decision when selecting there db.
b.    drive out potential projects to aid and encourage migration.

I probably won't have much time to get involved in this over the next
coiuple of months but may be able to get involved later.

any thoughts?

regards

steve
