Hi everyone,
does postgres support nested transactions?
If the answer is positive, can I use them
thru ODBC from a windows client?

Conversion from MS Access to Postgresql

From

Hi,

I am curently using MS Access and would like to convert my existing Access
database to Postgresql database (maybe into Postgresql dump file first if
neccessary). Is there any utility or program that can do that? Please
advise.

Thank you.

Regards,
Geok Leng

Unfortunately, Postgres doesn't support nested transactions.  At least I'm
99% sure it doesn't.

Hey,
I believe pgAdmin does that. Even if you don't use this part of it, you
should still use it for general management of your postgresql databases.  It
rocks.

I have a perl program which will load the .csv files you can dump from
Access.  That will only move the data, of course.  I generally find it
better to write a script to build the database by hand, but I think you
can export a script from Access that will work without too much editing.

Reply if you want my perl program.

Cheers,
                    Andrew.

G'day.

Having just done it, I can confirm that converting an Access database
to PostgreSQL is very easy.

All I did was as follows:

1. create an empty Postgresql database,
2. cretae an ODBC DSN on the Access machine pointing at the empty
database,
3, fire up Access and Save/As/Export all tables to the ODBC target.

Job done:-))

In fact, I had to do some massage to the results as the export process
does not create indexes nor sequences and I decidesd to change some of
the generated data types.

This was also easy using the pgdump utility to dump the data and the
definition for editing.

Be aware that any column names that include upper case letters in
Access will keep their capitalisation and require quotes in Postgresql.

HTH,
Stephen.
