Обсуждение: Just a crazy idea!
Is it possible to connect a DB in Postgresql to a DB in MySQL! I know its a crazy idea! H
Of course it is possible. In fact, it's easy. Just use JDBC or ODBC or OLEDB or a .NET provider and join to both database systems. There is nothing to it. I can make a join where tables from RMS and DB/2 and Oracle and PostgreSQL and MySQL are all participating in the SQL statement with ease. This technology is 15 years old. > -----Original Message----- > From: pgsql-general-owner@postgresql.org [mailto:pgsql-general- > owner@postgresql.org] On Behalf Of Hrishikesh Deshmukh > Sent: Thursday, May 26, 2005 2:05 PM > To: Postgresql-General > Subject: [GENERAL] Just a crazy idea! > > Is it possible to connect a DB in Postgresql to a DB in MySQL! > I know its a crazy idea! > H > > ---------------------------(end of broadcast)--------------------------- > TIP 5: Have you checked our extensive FAQ? > > http://www.postgresql.org/docs/faq
Could you point to documentation regarding this. This would be a big help. Thanks, Hrishi On 5/26/05, Dann Corbit <DCorbit@connx.com> wrote: > Of course it is possible.

Why, of course. Been' doing that.
All you need is to write a set of functios, for example in PL/perlU,
some of them being set returning functions.
For my purposes I did a function which connects to mysql to
call its encrypt function, and a function which returns "show databases"
and similar stuff.
Basically -- yes you can do it, though things getting tricky if you want
to have _read_ access to _big_ tables. :)

PS: For the reference, why do you need to connect to mysql?
I have a little schema in pgsql and some annotation in mysql; either way transfer of schema might result in data types etc conflicts. So if i could make these two talk then i don't have to worry about schema transfer. So the question and frankly i thought it was crazy thought! The replys so far indicate that i am not looney at all ;) Hrishi On 5/26/05, Dawid Kuroczko <qnex42@gmail.com> wrote: > On 5/26/05, Hrishikesh Deshmukh <hdeshmuk@gmail.com> wrote: > > Is it possible to connect a DB in Postgresql to a DB in MySQL! > > I know its a crazy idea! > > Why, of course.

Whether Hrishikesh is looney, however, is probably still an open question ...
LOL..............not looney!
