Hi all working my way through our views and all is going
very well.
We use datediff in MSSQL a bit and I read about the
field1::date – field2::date to return the days numerically.
Is there any way to get months and years besides guessing
days / 30 for months etc?

Hi,
i have the following SQL-Problem:
We are using 2 tables. The first, called plan, is holding planned
working times for employees per
tour:
plan.id_tour
plan.id_employee
plan.begin_time
plan.end_time
The second table 'work' stores the actual worked times for employees per tour:
work.id_tour

Hi,
I have a database in Oracle that I want to convert to PostgreSQL.
I have exported the scripts used to create the tables, constraints and
sequences in Oracle and wish to convert these to postgreSQL scripts now.
Is there an easy way to do this?
Regards,
Gary.

Hi there:
Thank you for the response, which gave me what I wanted.
Here is a follow-up question..
First a recap:
Table a contains the names of individuals, the places
they have visited and the year in which they were visited.
Let's see who has visited where and when:
SELECT * FROM a;
name
Yes I am using datepart, but not seeing how with a datediff.
Maybe I just need to do the date math and put a date part on the result.
I will play around a bit when I hit one not looking for days.

I went through a conversion from Oracle to PostgreSQL about 9 months ago.

installed the documentation.

Because i got no answer in pgsql.novice, i'll try it here. But maybe it

The pg_constraint table contains foreign key constraints. Here's
an example query that appears to work in trivial tests:

The PostgreSQL documentation is the place to start:
http://www.postgresql.org/docs
updating 40.000 records should take no longer than a couple of minutes.
I think you should optimise your query before going any further.
You have an inner SELECT sentence that executes before anything. It
joins EVERY row in your table (1,000,000+) with at most 3 other rows in
the same table, so
I am also very interesting in this very question.. Is there any way to
declare a persistant cursor that remains open between pg sessions?
This would be better than a temp table because you would not have to
do the initial select and insert into a fresh table and incur those IO
costs, which are oft

Isn't this a prime example of when to use a servlet or something similar
in function? It will create the cursor, maintain it, and fetch against
it for a particular page.

I also tried a simple select * from tblcase where clientum =

On both MSSQL and Postgres.
MSSQL was 3 secs, Postgres was 27 secs.

Basically the question was why would a view use an indexed search on one
result set but a seq search on a larger result set. Same view only
difference is how many rows are returned. The large result set was doing a
seq search and did not return after several minutes. The same sql ran in 135
seconds
