Обсуждение: Moving from Transact SQL to PL/pgsql

Hello:

I am implementing a new system using Postgres.  Well most of the system will
be new,
but some parts will be very similar to a system currently running under
M$-SQL.

The first issue will be getting up to speed on PL/pgsql.  Where can I find
primer on PL/pgsql, with lots of examples? How silimar is PL/pgsql to PL/SQL
under Oracle?

Thanks in Advance.

The PostgreSQL documentation is the place to start:

http://www.postgresql.org/docs/8.0/interactive/plpgsql.html

The PostgreSQL distribution has a file with some examples in it:

src/test/regress/sql/plpgsql.sql

The pgEdit distribution (http://pgedit.com/download) has a fairly 
extensive plpgsql example for importing and analyzing web server logs.

I'm not familiar with Oracle, but there is a porting section in the 
documentation:

Download openacs at http://openacs.org/projects/openacs/download/.  Look at directories matching
the pattern openacs-*/packages/*/sql/postgresql/.  The older openacs version 4.6.3 has more
examples than openacs 5.
