Hello,
I'm wondering if the following behaviour is the correct one for
PostGreSQL (7.4 on UNIX).
I've a table temp_tab with 5 fields (f1,f2,f3,...),and I'm a launching
the following request :
INSERT INTO temp_tab VALUES (1,2,3)
It will insert the values in the three first row whereas with info
Hello,
Is it a way to make the following UPDATE statement work with PGS 7.4
(UNIX) :
UPDATE dbit2 SET (dbit2_key,dbit2_c10,dbit2_vc200) = (ABS(-1),NULL,'xx')
WHERE dbit2_key=1
Or am I force to use the following syntax :
UPDATE dbit2 SET dbit2_key = ABS(-1), dbit2_c10 = NULL , dbit2_vc200 =
'xx

hello,
I have in db table with 3 columns... table name is l_model_to_part
columns: i_model_id, i_part_id, i_year
I have index on every column separately and primary key is (i_model_id,
i_part_id, i_year)
when I use: EXPLAIN SELECT * FROM l_model_to_part WHERE i_part_id=234;

of course, index_50 is BTREE index with one column (i_model_id)...

hi,
I want to track every change made to several tables...and was wondering
what is the best way... What are my thoughts at the moment are to make a
table like this :
id, table_name, field_name, old_value, new_value, timestamp
and triggers to do the logging.
but this will probably generate alot

hi,
Is it possible in Postgre to have enum type, so that later table fileld get values
from 1-6 (saving space)
1 - statex
2 - stateY
3 - stateZ
something like that and then constrain on this enum type..

CREATE DOMAIN is the answer:
CREATE DOMAIN mytype AS INT2 CHECK(VALUE>=1 AND VALUE<=6);

Hi all -
I am experiencing continually degrading performance on queries run
against the special system tables. I notice the slowdown when these
meta-data queries are run implicitly "behind the scenes" such as when
psql with readline support tries to complete a table name or pg_admin

I don`t know, if there is a special feature in postgresql for this.
The standard SQL-way is to create a lookup-table and define a foreign-key to it.
create table states( state_id int primary key not null
, state_text varchar(30) not null
, constraint uk_states_

hi, I need to find out the length of a varchar attribute ..
for example,if a I have an atribute "description varchar(256)" I would
expect to see this "256" in the pg_attribute table.
there's is an "attlen" In the pg_attribute but this doesn't give any
information
thanks in advance.

For my purposes, I was happier to get the output of format_type() and
parse it. This meant that I didn't have to carry around some magic
constant that wasn't part of the documented interface...

Does anyone know of any recent comparisons of postgres vs, Sybase ASE
12.5? I've looked around but can't find anything useful.
