Hi All,
I know it's polite to ensure that we do an explicit disconnect() once we're
done pulling the data. However, are there cases where an explicit disconnect
is un-needed? Something like specific idiosyncrasies of some DBI packages.
Eg: Postgresql vs MSSQL vs Teradata?
Anyone here uses perl to pull data from teradata?
just wondering if there's any caveats or such before I put effort into
figuring out how to use it.
Current script does this in sequence.
connect
pull data based on select
copy/import into PG
wait 30 secs
connect again.
I've turned on connection logging in PG and I noticed that I keep
seeing
LOG : connection received
statuses.
Which means that the script is connecting to the server every 3

Connection is to a MSSQL Server using DBI:sybase.
queries are the same, difference is one uses fetchrow_array() and the
other uses fetchrow_arrayref().
Supposedly, fetrow_arrayref() is faster than the other but doesn't seem
that way.

Just wondering how to if there's a way to determine the script I"m
writing is preserving the same connection string to the server.
I'm hitting the SQL Server to query from 5 tables (hence 5 different
sessions running under screen) at intervals of 30 mins. Is connect_cache
any use here under these
Hi,
just wondering how to achieve this. Want to query (PostgresSQL DB)
successively 3 different SQL.
1. delete from main_table
2. insert into main_table
3. update log_table
Can it be done successively w/o calling dbh->connect each time? how do I
put the prepare and the bind_param and the execute

Current method.. pseudo code.
while (1)
{
$from_datetime = time;
$to_datetime = time + $time_interval;
$query = "select count(*) from table where time >= ? and time prepare($query)
$sth->execute($from_datetime, $to_datetime)
$from_datetime = $to_datetime;
}
Results:

Nailed it down to DBD::Sybase issue and posting here for the archives..
Querying SQL server.
Data in SQL Server is
7/31/2007 2:37:51 PM
Returned data from perl-dbi is
Jul 31 2007 02:37PM
There's missing seconds in the output. Anyone knows why?
Can I please get a clue here?

Sorry, this isn't really a perl-dbi issue per-se. but I don't know where
else to post this issue. I can't find a "Perl" mail-list. There's loads
of list, but no perl-general.
Anyway.. pulling data from SQL-server using perl-dbi to be formatted as
a CSV file.
I had to do some tweaking to the outpu
