Hi there
I have a list of events that take place in a certain city at a
certain date. Now I would like to have the first two (ordered by
date) events for each city.
Is there a way to do this with one query?
I am using PostgreSQL 7.4.

TIP 8: explain analyze is your friend
Off the top of my head:
psql -c select into dump_table from old_table ; database
pg_dump -t dump_table -f dump_table.tmp database
sed -e s/dump_table/table_name/g dump_table.tmp table_name.sql
rm dump_table.tmp
You should now have a file called table_name.sql with the stuff
required

regarding errors like 'Object not
found' or build extensive automated regression tests but then you are going
to spent time for building those test cases which still may fail to detect
errors which are otherwise just easily detected by the compiler.

Hi Ken,
Under 7.3.x this option was removed, you need to test via:
SELECT * from table where field IS NULL;
thanx - works in both 7.1 and 7.3 - why do these guys keep fooling around
with these thangs?
select . where intnumber IS NULL

How does one check for an unset value in an integer field?
I've tried such things as:

Ultimately I want to know the group number for EACH rd_pk with the
highest run number. Can this be done in one query? Or will I need to
code with a loop?
Thanks

There is a fine line between genius and lunacy, fear not, walk the

Older data is moved into a seperate table to reduce the number of

The email at the bottom gave me an idea, but it doesn't quite work:
CREATE AGGREGATE accumulate(
BASETYPE = text,
SFUNC = textcat,
STYPE = text,
INITCOND = '' );

SELECT ('{' || ltrim(accumulate(',' || tablename),',') || '}') as cruft

WHERE hasindexes = 'f';
Would it not be more reasonable to have array_dims return an int or int[]?
Has anyone ever seen an array that does not start at 1?
The other problem I find with array_dims returning text is when you have a
multi-dimentional array like this IIRC;
array_dims('{{asd,fgh,jkl},{zxc,vbn,mlk}}') =

In text files on a Mac. the EOL character is a CR only.
What a messy thing this whole EOL cruft is.
To convert between these text formats on linux is easy if you have dos2unix.
The dos2unix on linux can perform many format conversions to and from unix,dos
and mac formats.

You will need two text utilities {dos2unix and sed} to do this in the simplest
way. They are fairly standard text utilities and are probably already on your

This is how I would do it :

| pgsql -c COPY table_name FROM STDIN USING DELIMITERS
Hi
You should use date instead of datetime since the data is only a date and
a date type uses less storage than a timestamp.
For time only data use type time or timetz if you want the timezone as
well. For data with a date and time use timestamp or timestamptz if you
want to include the

To make it easier to do this in SQL you can create a view like this :

I would agree that cron is probably the best solution.
You could have cron perform a query that has a trigger and performs all the

I am trying to write a function to step through an array and output each value
as a set {list}, I think.
This is what I want to do:

Turn :
attr6 | {val3,val7,val4,val5}
Into :
attr6 | val3
attr6 | val7
