endpoint_david

iswaria: you're using identifier quotes instead of string quotes
single quotes -> strings; double-quotes -> identifiers

iswaria

If i replace 8.2 for current, i am getting "The requested URL /docs/8.2/static/contrib.html was not found on this server."

newbie2

Hint: No operator matches the given name and argument type(s). You might need to add explicit type casts.
what the meaning of it?

jim

whatis "operator"?
whatis "argument"?
whatis "type"?

select * from c_order where c_order_id like '8%'

akretschmer

newbie2: use a paste site

newbie2

merlin83

newbie2: hmm, you can't use like on an int/bigint.. you'd probably want c_order_id::text like '8%'

jim

perhaps "like" is the operator

newbie2

http://pgsql.privatepaste.com/a585b50f44

jim

newbie2: have you found what those three words mean yet? here's a phrase you should look up too: "type cast" and "explicit type cast"
once you know what those mean, all the other words are plain english

xenoterracide

newbie2 what are you trying to do?
newbie2 I'm guessing you want to find order_id number 8 ?

newbie2

yes

xenoterracide

that would be where = 8;
LIKE is for searching text
the only other thing I could imagine that you might be trying to do is find all orders that begin with the number 8

albert_kam

Hi, im using 8.2.6. Is redirect_stderr configuration parameter enabled by default ? I can see that it's commented in the postgresql.conf. The postgresql doc doesnt say about the default value when the paramter is commented.

RhodiumToad

it's off by default
if you haven't edited the value, the commented-out value is the default one
and you can always show the actual value in effect, if the server is up, by connecting and using SHOW

albert_kam

RhodiumToad: that's convinient .. thanks for the info ..
the doc also doesnt say whether the directory specified in the log_directory parameter will be automatically created when it's unavailable .. but i guess i can find out by trying :)

RhodiumToad

iirc it won't be

albert_kam

ok ..
and if i want to see who issued what sql statements, is the log level of 'notice' sufficient ?

RhodiumToad

see log_statement
(or log_min_duration_statement=0)

albert_kam

sorry .. just reached that section in the docs .. :)

RhodiumToad

make sure you set log_line_prefix to something suitably comprehensive

albert_kam

i used '<%t %u@%e> '
time to restart to test things out
thanks alot for the help

RhodiumToad

albert_kam: you really need %p

albert_kam

why PID ?

RhodiumToad

otherwise you can't sort out which session is which

albert_kam

ohh ..
ok2 .. adding

gintek

hello

albert_kam

Hi, i wonder why my log outputs so much from a single select statement ? the log file for a single sql select : http://pastie.org/884285 .. the conf file for the logging : http://pastie.org/884290
i dont expect to see the parse or bind duration, and i dont want to see other statements issued on pg_catalog n such. i prefer only seeing the info for the issued sql statement ..
a simpler output that's more readable
what did i miss in the configuration ? :)

merlin83

albert_kam: how are you executing those queries?

albert_kam

merlin83: i did ctrl+e (execute sql) on aquadata studio app for the sql "select * from mytable"
lemme try it on psql

RhodiumToad

albert_kam: you'll see parse/bind/execute for queries executed using PQexecParams
albert_kam: the three phases have to be logged separately because for prepared queries, there might be one parse and multiple binds, and with some client interfaces there can be multiple executes per bind

albert_kam

wow, the log output from psql is very clean and is what i wanted, lol

RhodiumToad

(Action) wonders where WIT is
albert_kam: looks like "aquadata studio" is doing a lot of its own metadata queries
very inefficiently, too
I mean, a whole roundtrip to the server _for each column_ just to check whether it's declared not null?

albert_kam

I see ..

RhodiumToad

on a remote server that'd be seriously painful

albert_kam

thats the gui tool we use here as the sql manager, to do sql devel .. it's a shame it issued many sql statements ..
Strange why it's WIT, should be WIB. Btw, im in Jakarta, Indonesia. But perhaps people dont usually know Indonesia, but they know Bali :)

RhodiumToad

yeah, I guessed that from running select * from pg_timezone_names where abbrev='WIT';

gintek

i have problem with pg_tablespace_size('mytable') and i have error does not exist
but select * from mytable work fine ?

johto

gintek; pg_total_relation_size('mytable')

gintek

any idea what i`m doing wrong with this stupid problem ?

johto

gintek; tablespaces are something completely different

gintek

johto: why in manual pg_database_size(name) Disk space used by the database with the specified name

johto

that would work if you want to know the size of the database, but I don't see how that's related

gintek

pg_total_relation_size work fine
johto: thx

RhodiumToad

databases, tablespaces and tables (relations) are completely different things

Hi
Have you already an webservice using SOAP and postgres?

pif

hi, can someone explain the window functions 'lead' and 'lag'?

asfjio

hello, is it possible to view last changes made in some database if they are not executed through psql? something like history?

johto

pif; "lead" is the row following the current row and "lag" is the previous row

pif

iguanna

hi all
there was a way to set up the psql to show the row with the null values in order to distinguish from a empty row
but I don't remember which

johto

\pset null foo

iguanna

thanks

mage_

RhodiumToad: ?

RhodiumToad

mage_

you use FreeBSD, no ?
for you is it normal that /usr/local/lib/libpgport.a isn't provided by the -client package ?
I filled a PR for mapserver which require this file (http://www.freebsd.org/cgi/query-pr.cgi?pr=144985) but the fix of the package maintener is only to add a dependency on -server ...
it looks strange to me that you cannot build mapserver with postgis support without building the -server port

RhodiumToad

what is it referencing libpgport for?

mage_

it's required by mapserver when you enable PostGIS support

RhodiumToad

what functions is it trying to use?

mage_

I don't known .. the port fails to build without it
with :
/usr/bin/ld: cannot find -lpgport
gmake: *** [shp2img] Error 1

RhodiumToad

mage_

but I don't understand why -lpgport is listed with pg_config --libs and that that file (/usr/local/lib/libpgport.a) is missing
(on a machine where only -client is installed)

RhodiumToad

the client/server division in the freebsd port of pg is a bit questionable in parts, though that's partly due to the fact that the project itself doesn't provide any clear distinction

mage_

do you think I should fill a PR for this ?

RhodiumToad

probably

mage_

ok thanks

RhodiumToad

pg_config is a problem in itself because of confusion over whether it reflects the server build or the client
it really needs splitting into two

mage_

yep ..

RhodiumToad

there should be a server version that reflects what is needed to build server modules, and a client version

mage_

I'll include that in the PR

RhodiumToad

since there are clients like dbd::pg and (I assume) mapserver that want to use it for client builds, packaging systems tend to put in a version suited to the client needs,
which then buggers up any attempt to build server modules correctly

mage_

there should really be a libpq port in FreeBSD

SmokeyD

hey everyone. When I have a pl/pgsql function with "rows:=SELECT colname FROM tablename WHERE colname=val;", how can I test if that query returned any results?

johto

IF FOUND THEN .

SmokeyD

johto, cool, thanks

RhodiumToad

that statement is wrong anyway
you want SELECT INTO
(and FOUND isn't set by assignment statements)

SmokeyD

RhodiumToad, yeah. I just figured that out :) Thanks. I just do SELECT colname FROM tablename WHERE colname=var;IF NOT FOUND THEN blah....

RhodiumToad

SmokeyD

without the assignment

RhodiumToad

that'll fail too

SmokeyD

RhodiumToad

are you trying to get the actual value of "colname" or just check whether the row exists?

SmokeyD

just checking if it exists
I don't need the value

RhodiumToad

if exists(select * from tablename WHERE colname=var) then ...

SmokeyD

ah, that is better. Thanks

Diablo-D3

hey guys
whats the cost of a simple query?
like, is there a medium or large startup cost just to execute the query?

wulczer

Diablo-D3: there's some overhead of parsing and planning the query
you can avoid both by using prepared statements

Diablo-D3

okay so like
lets say I just want to return rows, and do no real thinking outside of just simple column matching
I have 1 server, a million rows

wulczer

you just want to get all the rows from the server?

Diablo-D3

vs
100 servers, the data set split up
how much would I be losing if I executed the same simple query on every one
