TIP 6: explain analyze is your friend
The syntax in Oracle is "is null" or "is not null" as in:
select count(*) from module_master where gatekeeper_status is null;
And yes that does work in PostGreSql. Now if your talking about the
Oracle function NVL, for Null Value, no that does not work and I don't
see a similar function in PostG
If your using V7.4 it doesn't but the following will create
one.
CREATE OR REPLACE FUNCTION to_date(text, text)
RETURNS "timestamp" AS'beginreturn to_timestamp($1,
$2);end;' LANGUAGE 'plpgsql' STABLE

Few, if any, application packages come with a preinstalled

engine, with a runtime license if applicable, or place the requirement on the

You may well be on the development team, but you are wrong for

You'll find PostGreSql and Oracle to be kindred spirits. Similar, but
different at the same time. I find performance very good, although you'll
need to tweak the system memory parameters from the defaults and the

Given the "fun" I've had with Sql*Server and it's sister Access, you'd be much better
off porting things manually. I'd precreate all of the tables/indexes and then move
the data with the aid of Access or a similar ODBC tool. As for the rest, re-write it
as Tsql is more like VB than pgplsql.
