Обсуждение: where is this problem (trigger)
I fire this trigger whenever my client updates a row
in the db:
CREATE FUNCTION notify_jobinfo() RETURNS "trigger" AS '
BEGIN
EXECUTE ''NOTIFY ''||TG_RELNAME||''_''||NEW.jobnumber;
RETURN NEW;
END
' LANGUAGE plpgsql;
CREATE TRIGGER notify_jobinfo AFTER UPDATE ON jobinfo FOR EACH ROW EXECUTE PROCEDURE notify_jobinfo();
CREATE TABLE jobinfo ( acode text, jobnumber text DEFAULT
nextval('public.jobinfo_seq'::text), creationdate date DEFAULT now(), shortdescription text, projectcode text,
holdnumbertext, insertioninfo text, jobtitle text, insertiondate text, iscomplete boolean DEFAULT false,
isbilledboolean DEFAULT false, CONSTRAINT "$1" CHECK ((jobnumber <> ''::text))
);
My problem is that I have had to import legacy data
for the jobnumber column. My client was originally
using an excel file. they were free to do as they
pleased and there are jobnumbers like '1041.01'
'1041.02'.
I can not seem to update these rows because of the dot
in the jobnumber field. I have found that I can change
the dot to an underscore but I thought I would ask if
there is a better solution.
here is the error:
UPDATE jobinfo SET isbilled = false WHERE jobnumber =
'1162.01';
ERROR: syntax error at or near ".01" at character 20
CONTEXT: PL/pgSQL function "notify_jobinfo" line 2 at
execute statement

I can hardly believe the dot in '1162.01' is causing the error.
There must be some other reason. Without showing the trigger
procedure's code it's impossible to tell what's really wrong.

Foo_1023.01 is not a valid identifier so you might want to double quote the string since "Foo_1023.01" is one.
I run an application which connects to my pgsql DB. How could I see which query is sent to DB when, an example, i push some application button (such ´find´). sds Eric Anderson CPD Via Net SAO 11-66432800
Great I got the double quotes in the trigger... like
this:
CREATE FUNCTION notify_jobinfo() RETURNS "trigger" AS '
BEGIN
EXECUTE ''NOTIFY
"''||TG_RELNAME||''_''||NEW.jobnumber||''"'';
RETURN NEW;
END
' LANGUAGE plpgsql;
and it works great... however, i did a pg_dump of the
db to back it up. On a lark I started looking through
the file and I decided to look at the dumped trigger
and this is what I see.
--
-- TOC entry 29 (OID 17180)
-- Name: notify_on_update(); Type: FUNCTION; Schema:
public; Owner: postgres
--
CREATE FUNCTION notify_on_update() RETURNS "trigger" AS '
BEGIN
EXECUTE ''NOTIFY ''||TG_RELNAME||''_''||NEW.jobnumseq;
RETURN NEW;
END
' LANGUAGE plpgsql;
Ouch... it looks like pg_dump forgot my double quotes.
Do you have any ideas? If I reimport this dump file
the triggers won't work when it meets a row with a dot
in the column. Of course I can just update my data to
use the underscore instead of the dot.....

Ignore that last post.... of course I have a
production machine and a development machine and I
should have updated the development machine before
opening my mouth...
Everything works just fine.... thanks.

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 There are two ways to do it. The server-side approach is to increase logging levels in the config file and then "pg_ctl reload". See http://www.postgresql.org/docs/7.4/interactive/runtime-config.html#RUNTIME-CONFIG-LOGGING for the stuff involved. The other way to do it is client side. In this case, you have to increase the logging level of your database connection. For example, if you have a perl DBD application, find the initilization of the database handle (by convention named $dbh) and then add $dbh->trace(2); After it.
