Hi,
could somebody explain me please why following select
SELECT docid FROM prod.guids
GROUP BY docid HAVING( COUNT(docid) > 1 )
taking 15 min on 2 Proc Box on 1M rows, where number of duplicates
around 300K,
and docid indexed and not null and char(16).
May be I am doing something wrong?
Hi,
I have some SQL function, just regular function selects data by using 4
joins nothing fancy,
but one thing pretty noticeable,
I have to display 3 different columns with same date formatted
differently,
here are 3 different snippets:
1. SELECT t.x,t.y,TO_CHAR(t.dt, 'DD/MM/')
FROM
function call, would be much helpful in such case.
In comparison with Microsoft SQL, productivity of using
profiling/debugging tools sorry to say that, far behind.

Hi,
I have interesting question that stops me now.
Suppose I have 2 functions
1. preparestate
2. doajob
first allocates some state using
MemoryContextAlloc(TopTransactionContext)
or something, another function using that memory.
question is how I lookup that memory in second function doajob?

now it stays, that's only I care about.

Just want to add my $0.03 on that.
single file DB has some benefits as:
1. ability to allocate one continues chunk on disk,
significantly reduces disk seeks,
mostly ancestral but still true today ( I still see DB living on none
arrays )
2. And of cause countless design considerations.
