DBI Version Problem
Pardon me if this has been covered before; I can't reach the archives, and I'm the impateint type. ;-) I'm using Perl 5.6.0 on OpenBSD 2.9; it's worked quite well for me so far. After just installing MySQL 3.23.37, I figured the smart thing to do to work with it would be to get the appropriate Perl modules installed. So I went out and grabbed DBI-1.20, which installed just fine, and then DBD-mysql-2.0902. For some reason, when I ran my "perl Makefile.PL" command, I got these errors: DBI object version 1.20 does not match $DBI::VERSION 1.15 at /usr/libdata/perl5/i386-openbsd/5.6.0/DynaLoader.pm line 219. BEGIN failed--compilation aborted at /usr/local/libdata/perl5/site_perl/i386-openbsd/DBI.pm line 180. Compilation failed in require at /usr/local/libdata/perl5/site_perl/i386-openbsd/DBI/DBD.pm line 1740. BEGIN failed--compilation aborted at /usr/local/libdata/perl5/site_perl/i386-openbsd/DBI/DBD.pm line 1741. Compilation failed in require at Makefile.PL line 5. BEGIN failed--compilation aborted at Makefile.PL line 5. I'm guessing that OpenBSD installed DBI-1.15 with Perl on the basic system install. In any case, how would I go about fixing this? Like I said, DBI-1.20 installed just fine, with "make test" giving no errors. Thanks, Alex Kirk

RE: date format in Oracle
9i is a lot more timezone aware - if thats of any use. You can have a data
type of "TIMESTAMP WITH [LOCAL] TIMEZONE", however I'm not sure of whether
the Oracle::DBD supports the new data types.

RE: accessing sybase & oracle simultaneously
I don't have an example for Sybase, but I have done this sort of thing with
a couple of local and remote Oracles as well as multiple local Oracles.
Basically, you connect to each one as you would expect and assign a
different handle to each connection. From there on, it doesn't matter
whether they're local or remote since everything is done via DBI, which
nicely insulates you from such headaches. :)
A scrap of code:
-8<-
#!/usr/local/bin/perl
use DBI;
my $sid1='PCUS';
my $username1='pcus_username';
my $password1='pcus_password1;
my $sid2='SDI';
my $username2='sdi_username';
my $password2='pinecone';
END {
$dbh1->disconnect();
$dbh2->disconnect();
}
$dbh1=DBI->connect("dbi:Oracle:".$sid1,$username1,$password1,{AutoCommit=>0}
) || die "Can't connect to database $s

$dbh2=DBI->connect("dbi:Oracle:".$sid2,$username2,$password2,{AutoCommit=>0}

Subject: accessing sybase & oracle simultaneously
Does anyone have a sample code which demonstrates
using DBI to access both a remote oracle and local
sybase servers simultaneously?
Goal is to connect & perform same operations
(insert & select & delete) on both databases. From a
code level perspective, each insert
and update must in affect be performed twice ( once
for each datastore oracle/sybase). This would render
the databases equal in terms of information added
& and removed.
I have an idea of how I might try it but wanted to
know if anyone had done it or knows exactly how,
caveats, etc. The oracle queries would be to a
remote host while the sybase queries would be on
the local host.
TIA!

Umm, how about this:
$syb = DBI->connect('dbi:Sybase:foo', ...);
$ora = DBI->connect('dbi:Oracle:bar', ...);
It's a bit tricky, but I hope you get the idea :-)

Take a look at DBD::Multiplex (The one shipped with the DBI is old.
Search the archives for the url of the latest, or some kind soul
will post it.)

[EMAIL PROTECTED] wrote: > > Does anyone have a sample code which demonstrates > using DBI to access both a remote oracle and local > sybase servers simultaneously? This should be quite straightforward to do - just open connections to the appropriate database servers using DBD::Oracle and DBD::Sybase and then run with it. DBD::Sybase doesn't distinguish between "local" and "remote" servers - it only knows about a logical server name that the Sybase client libraries then use to look up the appopriate connection parameters in the interfaces file.

setting csv_eol=\015 when file format is saved as Macintosh results in

i.e. it's only confused SOMEtimes. Somewhere, it's assuming the file is
a DOS file, even though I'm setting csv_eol properly, the question is
WHERE?
my $dbh =
DBI->connect("dbi:CSV:f_dir=${dbi_connect_dir};csv_sep_char=\t;csv_eol=\0

All well and good, except that the file is generated by a whole suite of

embedded in an .asp page, formatted to an html table, parsed by
HTML::Parser, and tested for integrity by script # 3) and is read for
report-generation by something like 10 other scripts.
I don't want to go back through all the scripts and change the input and

Re: Correct Oracle environment Needed for DBI
Susan, My guess is that you installed DBD::Oracle with your environment pointing to 8.1.7. When you install DBD::Oracle, it is linked with the Oracle client libraries. If you run a program linked in an 8.1.7 environment, but (because of your environment variables) it picks up the dynamic libraries of an older version, you're asking for trouble. You should provide your DBD::Oracle with the client libraries it was linked with at install time. So, if you have a mixed version environment, the best way to go is : * Install DBD::Oracle against the highest version * Always keep your environment variables (ORACLE_HOME, PATH and LD_LIBRARY_PATH) pointing to this same environment. If you need to connect to other versions, use SQL*Net. Hope this helps, Brgds, Mark [EMAIL PROTECTED] wrote: > I have a program that sets the Oracle environment for 8.1.7 and connects to > the database just fine.

RE: Select X number of rows
Yes. Run a connect to each DB you want to work with. You can then run queries with a where clause of 'rownum <= 20' to get a sampling of a table from each DB. I'm not sure about a page count myself, but you can check the number of records in each DB in each table with a 'select count(*)' query statement. These are pretty much SQL questions for the most part. $dbh1=DBI->connect(.); $dbh2=DBI->connect(.); $dbh3=DBI->connect(.); . . $sth1=$dbh1->prepare(); . . $sth2=$dbh2->prepare(); . . $sth3=$dbh3->prepare(); . . . . $dbh3->disconnect; $dbh2->disconnect; $dbh1->disconnect; -Original Message- From: Purcell, Scott [mailto:[EMAIL PROTECTED]] Sent: Tuesday, October 02, 2001 7:36 AM To: '[EMAIL PROTECTED]' Subject: Select X number of rows Hello, I am a Perl guy, not a DBA.

RH7 - Oracle 8i Enterprise - DBI - libskgxp8.so
Hi all, I have recently installed Oracle 8i enterprise (8.1.7) on a Redhat 7 system... and, using some advice from otn.oracle.com discussion forums, I am able to run a database, use svrmgrl, and sqlplus... now, I want to connect via DBI::Oracle to another oracle database that is running elsewhere on the network... but keep getting a message that libskgxp8.so can not be found... I have for the most part installed all of the components of Oracle 8i enterprise It's correct as this file does not exist anywhere on the system... only a libskgxp8.a - in $ORACLE_HOME/lib - where does this .so come from? where can I get it... The env LD_LIBRARY_PATH is set to $ORACLE_HOME/lib Any help appreciated. Neil Streeter

I'm afraid that Oracle's handling of timezones is primitive at best.
There is no date format modl string for time zone and the function
new_time() only recognises a very Americano-centric set of zones.
You can though use the environment variable TZ (on SVR4 systems and
BSD if memory serves) to establish the zone of the session:
TZ=GMT+8 sqlplus scott/tiger
or
$ENV{TZ} = 'PST8PDT';
$dbh = DBI->connect("DBI:Oracle:","scott","tiger");
You can find the available zones in /usr/share/lib/zoneinfo on SVR4 or BSD.
From there, you can 'mask' the timezone in your date string like so:
insert into datetest values ( to_date('Thu Sep 20 15:03:10 PDT 2001'
, 'Dy Mon DD HH24:MI:SS --- ') )
As an aside, most other RDBMSs support timezones in the data, but
Oracle is just a bit slow on this.
