[GENERAL] LIMIT modifier
I'm dealing with a project that requires me to query a MS SQL Server. Not
a PostgreSQL issue I know but I want to ask if the LIMIT modifier is SQL
standard? MS SQL Server uses a TOP modifier.
select top 1 * from xxx;
Whereas all the SQL RDBMS' I've used before used
select * from xxx limit 1;
Any enlightenment is appreciated. (I'm putting notes in the code to
reflect the non-standard stuff I've had to deal with.)
TIA,
Rod

When I said that the sort order could be arbitrary, I meant /arbitrary/. As in no amount of ORDER BYs will save me from this one arbitrary; the records could be in any order the user specifies. The idea is that in PHP I'd be using an array to keep track of the custom order that the results should be returned in, using the array index to store the sorting order and the values to store the table's primary key, like so (note that this isn't the code I'm using, it's just an example): ?php $sort[0] = 3; //First record to return (3 is the primary key of the record) $sort[1] = 1; //Second record to return $sort[2] = 2; //Third record to return ... //and so on. ? It would be possible to use this array in a query, but this wouldn't work well for large data sets as you would be sending the whole array back and forth a lot. Presumably the reason you want to do the sort in the database is because the dataset is large enough that you don't want to buffer the data in PHP in the first place. I'm not sure how large the data sets will be, but yeah, I'm trying to keep as much processing and memory out of my PHP scripts as possible. That and PostgreSQL already has a well debugged sorting algorithm, so I'm trying not to reinvent the wheel. The other thing is that most likely the query will be a one time thing until the user freezes it into a final sorted order, and storing lots of data in the database just to handle one query seems like a pain in the rear to me. I think the temp table solution won't be that simple either. You will need connection pooling and some way to keep requests from the same web session using the same postgres session. If I created the table and then executed the query in the same script, I don't see why it wouldn't work. But I agree, it leaves something to be desired, and I am not familiar enough with how PHP handles persistant database connections to know what the side-effects would be. You may want to use regular tables which are named by session id and the have some clean up process that removes tables that are no longer needed. What I'll probably do is use the CASE syntax mentioned by Scott Marlowe to order the query until it is in a final form where it will be accessed frequently using the same ordering, and store /that/ ordering in the database in a more-or-less permanent form. If generating a query using CASE becomes too unwieldy, then I'll look at using a regular table with session ids to handle it. Anyway, thanks for all of your help everyone. I think I've got enough ideas to start working on it. -- ___ Nathaniel Price http://www.tesserportal.net Webmaster ---(end of broadcast)--- TIP 4: Don't 'kill -9' the postmaster

[GENERAL] Changing user
Dear All,
I have a simple table
CREATE TABLE table1{
user name,
si numeric
};
Also I have function:
CREATE FUNCTION check1(numeric) RETURN text AS'
DECLARE
SI ALIAS AS $1;
username name;
BEGIN
username:=(SELECT user FROM table1 WHERE si=SI)
SET SESSION AUTHORIZATION username;
RETURN username;
END;
'LANGUAGE 'plpgsql';
However, when I call the function I get the error:
ERROR: syntax error at or near $1 at character 28
CONTEXT: PL/pgSQL function check1 line11 at SQL statement
If I comment out the SET SESSION ... the function works, i.e. it outputs a
valid username. I create and execute the function as a superuser.
Any suggestions?
Many thanks
Colin

During the test, I saw a lot of messages in the database log file: NOTICE: _sc_id=0, _add_flag=0, _itemcount=0, _i_id=597, _pp_i_id=159, c_id=32760 ERROR: deadlock detected WARNING: Error occurred while executing PL/pgSQL function shopping_cart WARNING: line 311 at SQL statement WARNING: ROLLBACK: no transaction in progress The shopping_cart transaction does update/insert to shopping_cart and shopping_cart_line tables, and if it is a new shopping_cart, it queries the SEQUENCE scid to get a new shopping_cart.

Re: [GENERAL] PostgreSQL Training
Bret. The MySQL certifications, are international skillset certifications, like MCAD, MCSD, MCSE, RHCE, and LPI certifications, and, from what I understand, similarly, internationally recognised. In my experience these have less to do with being proficient at a disipline and more to do with marketing (of the individual holding the certificate and of the application). The people here are more doers than marketers. That being said, PostgreSQL could sure use some more marketing. My wife is a software developer, by profession. She also trains people, and has trained lecturers, in some of the development software in which she develops. Sounds like there is room for YOU and your wife could get involved in setting up and administering some kind of PorstgreSQL certification program! I have no idea if this would be feasible in the PostgreSQL community or not, and I've read here that Red Hat is doing just that with their dialect of the PostgreSQL server (maybe somebody else can elaborate). As far as books, I just know returned a book to the library, 'Learn SQL in 14 days' or something similiar (sorry, don't remember the author) and the concepts presented there (which includes triggers and procedures, etc.) are transferrable to any SQL database. There are some good PostgreSQL specific books, too (including Bruce Momjian's). If you think there is a need for a basic starter's guide to PostgreSQL you might put one together and offer it (for money, or otherwise!). You are right in that PostgreSQL could benefit from more marketing.

[GENERAL] Is it not datestyle that determines date format output?
The way PostgreSQL deals with the date format is confusing me... I need PostgreSQL to return dates from selects at this format: dd/mm/, but it insists in returning it as -mm-dd.

I checked it executing: SHOW DATESTYLE and I got: DateStyle --- ISO with European conventions When inserting dates, PostgreSQL understands very well my date format like dd/mm/, but it is also important to get the date like that.

[GENERAL] VACUUM ANALYZE -vs- ANALYZE on an insert-only table.
If I have a table that I only use for INSERTs and queries (no UPDATEs or DELETEs), is it enough to just run ANALYZE on the table instead of VACUUM ANALYZE? In other words, is running a VACUUM on a table useful if all that you're doing is INSERTing into it? My understanding of VACUUM is that it cleans up stale tuples that are left after UPDATEs and DELETEs. The reason that I'm asking this has mainly to do with performance. I've got a lot of large tables ( 1 million records) in my database. Running a nightly VACUUM ANALYZE takes a while ( 1 hour) to run.
