Re: MS ACCESS text field truncated

RE: Accessing oracle from windows 2000
Just wanted to let people know what worked for me for connecting to an
Oracle database on a Windows XP platform, using both DBD::ODBC *AND*
DBD::Oracle. Thanks to Jeff Urlwin for all the help - see Jeff's
suggestions below for reference. NOTE that my version of ActiveState
Perl is 5.8.2.
1. Using 'ppm uninstall DBD::ODBC' I uninstalled DBD::ODBC.
2. Using 'ppm uninstall DBD::Oracle' I uninstalled DBD::Oracle.
3. Using 'ppm uninstall DBI' I uninstalled DBI.
4. Did 'ppm install
ftp://ftp.esoftmatic.com/outgoing/DBI/5.8.2/DBI.ppd '
to install the DBI binary for AS Perl 5.8.2 from Jeff's
repository
5. Did 'ppm install
ftp://ftp.esoftmatic.com/outgoing/DBI/5.8.2/DBD-ODBC.ppd '
to install the DBD::ODBC binary for AS Perl 5.8.2 from
Jeff's
repository.
6. Did 'ppm install
ftp://ftp.esoftmatic.com/outgoing/DBI/5.8.2/DBD-Oracle.ppd '
to install the DBD::Oracle binary for AS Perl 5.8.2 from
Jeff's
repository.
Then for the DBD::Oracle test, I created this small test script:
#!C:\Perl\bin
use strict;
use DBI;
my $dbh = DBI-connect('dbi:Oracle:host=MY_HOST;sid=MY_SID',
'my_user',
'my_password',
{ RaiseError = 1, PrintError = 1 }
) || die Can't connect: $dbi::errstr;
print Successful Connect: \$dbh=[$dbh]\n;
And it worked.

Jeff, I still don't know what my problem is - maybe you can help me.
How do I know if I have the Oracle client libraries installed
on this WinXP machine? I have a C:\Oracle\Ora81 directory
which contains a bunch of folders, so I'm guessing I have at
least the client installed.
I do have a C:\Oracle\Ora81\network\ADMIN\tnsnames.ora file.
Do you know why I keep getting this error:
Error: no suitable installation target found for package
DBD-Oracle8.
Yep. That's a PPM error, not an oracle error.
when I do 'ppm install DBD-Oracle8.ppd' ?? Is it because I'm
using an Activestate DBD-Oracle8.zip from the ActivePerl 6xx
folder when I actually have ActivePerl 5.8.2 (ActivePerl 8xx)
?? Would your DBI and DBD::Oracle binaries solve my problem?
I'm guessing they would ;-)
Probably. The best thing to do is let me know which version of Perl.
If you have 5.8.2 perl (build 808?), then you should be able to do
(hmmm...forgot the URL...ah, there it is):
ppm install ftp://ftp.esoftmatic.com/outgoing/DBI/5.8.2/DBI.ppd
ppm install ftp://ftp.esoftmatic.com/outgoing/DBI/5.8.2/DBD-ODBC.ppd
ppm install ftp://ftp.esoftmatic.com/outgoing/DBI/5.8.2/DBD-Oracle.ppd
Thanks for any input you can give.
Np

Ok -- I thought I'd chime in here. I *humbly* consider
myself knowledgeable about this topic ;).
You can choose to use either DBD::ODBC or DBD::Oracle under
windows platforms (with caveats and issues that will be
outlined below. Both will/should work under most
circumstances. However, as the *developer* of DBD::ODBC, I
use DBD::Oracle when using an Oracle data source. It's not
that I couldn't use DBD::ODBC, but...
a) DBD::Oracle is the most reliable and *fastest*
method to talk to Oracle.
b) The Microsoft Oracle ODBC drivers are terribly painful to
use
c) The Oracle ODBC drivers are a *bit* buggy and
nowhere near as fast as DBD::Oracle
d) YMMV with 3rd party ODBC drivers. I used 3rd party
drivers in 1993 or so, when DBD::Oracle didn't work on the
Windows platform. In fact, using Win32::ODBC and 3rd party
Oracle ODBC drivers was what prompted me to help port
DBD::Oracle to Windows Perl in the first place...many moons ago
;)
As stated above, I *prefer* using DBD::Oracle when connecting
to Oracle. You need to have the Oracle client installed --
and licensed -- on your machine. ActiveState *stopped*
directly supporting DBD::Oracle binaries a while ago (after
the Perl 5.6.x timeframe and before 5.8.x timeframe). Using
anything but a DBD::Oracle built with the same version of
perl you are using is likely to be problematic. Since AS
stopped putting up binary versions, I started to. You can
get DBI, DBD::Oracle, DBD::ODBC and DBD::DB2 for current
versions of AS Perl (5.8.3) from my repository.
If you
get DBD::XXX from my repos, also ensure you get DBI from my
repos. If you don't, you are at your own risk with the
binary compatibility. I've announced these repositories in
the past via [EMAIL PROTECTED] and [EMAIL PROTECTED], so
they should be in google too.
That said, there is a known issue with 9x client libraries
with the binaries of DBD::Oracle. The next version of
DBD::Oracle can handle that better, but you may get an error
related to the lack of OCILobWriteAppend in earlier Oracle
OCI clients...if so, for now, I recommend you update your
client while
Benchmarking Oracle connections on Windoze XP with DBD::ODBC and DBD::Oracle

Is the 1st column saying that ms_odbc_driver is 37% faster than the
ora_odbc_driver, and the ora_dbd_driver(DBD::Oracle) is 92% faster than
the ora_odbc_driver?? The last 2 columns have me confused too. Any
help is appreciated.

Hello Jeff, At first, I did put type longvarchar, then I read the doc and copy the type LONGVARCHAR to my code. All the other parts very simple because I use the default way to make connection and create prepared statement. The field $address is mapped to Text field of size 255 in MS ACCESS DB, but got truncated to 50, which is the default field size in MS ACCESS $iSth-bind_param(1, $name); $iSth-bind_param(2, $address, DBI::SQL_LONGVARCHAR); Let me know if there is anything else you want.

Ok I'm having a brain-fart - can someone clue me in as to how
to read this last section that compares the different methods
using percentages? Is the 1st column saying that
ms_odbc_driver is 37% faster than the ora_odbc_driver, and
the ora_dbd_driver(DBD::Oracle) is 92% faster than the
ora_odbc_driver?? The last 2 columns have me confused too.
Any help is appreciated.
Ok -- First, let me comment on the test. I understand that connection
times are important, but only testing drivers speed based upon
connection/disconnection time is probably not a good test and results may
vary wildly... I *do* have a hard time I believe that the Oracle ODBC
driver is *slower* that DBD::Oracle.
I updated your script, made it a bit more generic and added my ODBC drivers
in, I get strange results like yours above. From my results, I don't
believe the cmpthese function is correct -- and is sadly broken. Here's
what I show, using a local Oracle database, ACCESS, a remote SQLServer
(which always has a fast connection) and a sadly underperforming DB2 server
(remote also). The SQLServer and DB2 server are both on 100MBit switched
connections to my machine.
Benchmark: timing 100 iterations of DBD_ODBC_ACCESS, DBD_ODBC_DB2,
DBD_ODBC_MSORACLE, DBD_ODBC_ORACLE, DBD_ODBC_SQLSERVER, DBD_ORACLE...

From the results you have and I have, cmpthese seems broken -- or is
*definitely* not correct on Win32 because it's using usr and sys time, not
wallclock time. (I guess that depends upon your perspective of broken --
maybe just broken on Win32 would be more correct, until proven otherwise).
Also note, timethese is sadly reporting that I can perform 72.36 connections
per second using DB2, even though 100 connections took more than a one
minute...
Also, for reference, my script (which will be in the subversion repository
by the time you read this) is:
---
#!perl -w
use strict;
use DBI;
use Benchmark qw(timethese cmpthese timeit countit timestr);
my %conns = (
DBD_ORACLE = sub { doconnect(dbi:Oracle:URLWINLT); },
DBD_ODBC_ORACLE = sub {
doconnect(dbi:ODBC:PERL_TEST_ORACLE); },
DBD_ODBC_MSORACLE = sub {
doconnect(dbi:ODBC:PERL_TEST_MSORACLE); },
DBD_ODBC_SQLSERVER = sub {
doconnect(dbi:ODBC:PERL_TEST_SQLSERVER); },
DBD_ODBC_DB2 = sub { doconnect(dbi:ODBC:PERL_TEST_DB2); },
DBD_ODBC_ACCESS = sub {
doconnect(dbi:ODBC:PERL_TEST_ACCESS); },
);
sub doconnect ($) {
my $connstr = shift;
my $dbh = DBI-connect($connstr,
$ENV{DBI_USER},
$ENV{DBI_PASS},
{ RaiseError = 1, PrintError = 1 }

uhm... so, this can cause a corrupted table?
Not physically corrupt, no. But a LOCK TABLE foo READ you did earlier
may be either a) no longer in effect, or b) still in effect but held by a
connection to the database that the mysql server doesn't yet realise is
dead.
Remember that the connection may have failed due to a temporary
network condition so the original server process may still be running.
and this can happen with other languages I believe? (as you said mysql
client library)
Yes.

Cheers Guys,
I have a related question, if I've stored some private_ data in the $dbh
object, and I wish to print this data to a logfile whenever an error
occurs,
I wanted to use an ErrorHandler subroutine which reads the private_ data.
But if the error occurs through an $sth I get a DBI::st rather than the
DBI::db handle back - and thus no access to the private data (I'm only
able
to control the creation code of the $dbh not any subsequent $sth's). So if
you have an $sth, is it possible to get the corresponding $dbh back from
the
$sth - if that makes any sense.
Is the documentation not clear about $sth-{Database} ?
Tim.
How to format a DATE field?
OK--here's probably the easiest question ever posted on this forum. I can
tell it's Friday night, cuz my brain must be completely shut down.
I'm reading records from an Oracle database using the DataHash method. One
of the fields in the records being retrieved is type DATE. I want to
convert that date to the format MMDD and print it to an output file.
Here's what I tried:
while($db-FetchRow())
{
%row = $db-DataHash();
$formatted_contact_date = sprintf (%04d%02d%02d,
$row{CONTACT_DATE});
print Formatted contact date is $formatted_contact_date.\n;
.
.
.
}
Output I'm getting from the above is Formatted contact date is 2004.
The month and day are always zeroes. How do I get the date into the format
I want? (I know, I know ... sigh.)
Thanks.

GOT IT--NEVER MIND! RE: How to format a DATE field?
Never mind--I got it--I just have to use substr instead of sprintf. Thanks,
folks.

Can I reset the pointer in a DataHash?
I would like to read all the records from a table in once, in a single SELECT, and then use while($db-FetchRow()) and the %row = $db-DataHash() method to process through them. Is there a way to reset the pointer to the beginning of the recordset so that I can process the records a second time without reading them all back in from the database? I tried just repeating the while($db-FetchRow()) statement after I'd finished the first round of processing, but it didn't work. Thanks ... Laurie A.

please
You are correct, the syntax is not correct. As pointed out by the error
message, (`) is not a valid character in Oracle SQL. You should use ()
to quote column names if the names are case sensitive or contain
otherwise illegal characters for column names. That's one of the
differences between MySQL and Oracle SQL.
