Re: DBD::Sybase question
Hi,
Yes, I know about that script - but you should still be careful when you
use a binary built with a 12.5.1 client installation against a 15.0
run-time. It would probably be better to rebuild.

Many thanks for the reply and the information Michael - it's been very
useful.
It may interest you to know that we've successfully been able to run our
regression tests (which use DBD::Sybase 1.00) without changing anything
EXCEPT following the Sybase SDK 15 documentation and running
$SYBASE/OCS-15_0/scripts/lnsyblibs create - which creates soft-links
under $SYBASE/OCS-15_0/lib for backward-compatability (as you quite
rightly
pointed out that Sybase have changed their lib names by adding a 'syb'
suffix to each one - eg. libct.so is now libsybct.so - the soft-links
allow
a preservation reference of 'libct.so').
By the way, please note that there seems to be a bug in
$SYBASE/OCS-15_0/scripts/lnsyblibs as follows:
BUG in red:
createlinks()
{
ls libsyb*.s[o|l] |\
awk '{
print ln -s $1 lib substr($1, 7, length($1) - 6)
}' | sh
}
FIX in blue:
createlinks()
{
ls libsyb*.s[ol] |\
awk '{
print ln -s $1 lib substr($1, 7, length($1) - 6)
}' | sh
}
Once again, many thanks for your valuable feedback.

Minesh

Re: DBD::Sybase question
You can interact with an ASE 15 server with a 12.5.1 client with no
particular problems. There may be some issues with the more esoteric
OpenClient functionality, but as DBD::Sybase doesn't use this it shouldn't
be a problem.
So the short answer is that you can keep your current environment and add
the ASE 15 server to the interfaces file.
Moving forward however you should consider upgrading the client and
DBD::Sybase, so to answer your other questions:
- DBD::Sybase 1.00 will not build with OCS 15 due to changes in the
library
names (and maybe other problems as well - I have never tried it).
- A DBD::Sybase binary should only be used at run-time with the same OCS
version that was used to build it (note: EBF changes are OK without a
rebuild)
- To have multiple DBD::Sybase binaries with a single perl installation
you
need to set the PERL5_LIB env. variable or use the use lib directive in
your scripts to point to the directory that holds the DBD::Sybase binary
that you want to use. It is certainly feasible, but you obviously need to
set something up so that these settings are automatic (i.e. you don't want
to have to edit your scripts to set the correct environment :-)
That being said I only have a 15.0 installation here, and use it to
interface with all sorts of Sybase servers (including an antique 4.9.2
server!) and I have yet to see any problems.

Subject:DBD::Sybase question
Hi,
We are conducting a proof of concept to upgrade Sybase ASE 12.5.1 and
OpenClient 12.5.1 to Sybase ASE 15.0 and SDK 15.0 on Solaris 2.8. Our
current environment details are as follows:
Perl 5.005 (5.0 patchlevel 5 subversion 3)
Sybase OC 12.5.1
Sybase ASE 12.5.1
DBI 1.37
DBD::Sybase 1.00
We'd like to retain Sybase 12.5.1 and it's perl environment as described
above but create a new environment for Sybase 15.0.0 and have the
following
questions (any feedback will be greatly appreciated):
- do we need an entirely separate perl, DBI and DBD installation for the
Sybase 15.0.0 side of things?
- do we need DBD::Sybase 1.07 for Sybase 15.0.0
- is there anyway we can use the same perl installation but point it to
either DBD::Sybase 1.00 or DBD::Sybase 1.07
Thanks Regards,
Minesh Thaker

Oracle functions through DBI?
Hello, I was wondering (and found nothing bout that on the web), can I use DBI to execute some oracle DB functions? Here's my case: I have a (oracle) function that returns a new free ROW ID randomly and I have to manage that RI from a perl script. Can I use DBI to submit the request to oracle? for me it would be much more simple and efficient than the same old way!! thanks Riccardo
MySql function
Hi Everyone, i did the following $dbh-prepare(UPDATE contentTable SET filename = '$dbfile date_modefied = 'CURRENT_DATE()' time_modefied = 'CURRENT_TIME() WHERE ext = '$ext' ) and the value of the current date and current time were not updated on the table. It seems perl interpolated the function CURRENT_DATE() and CURRENT_TIME() .everything else is ok can someone help with a way out. Rgds __ Do You Yahoo!? Tired of spam? Yahoo!

Why did you put single quotes around the MySql function calls? That tells
MySql that these are strings, not function calls.
Also, you should be using placeholders for the variables. Try this:
$dbh-prepare('UPDATE contentTable SET filename = ?, date_modified =
CURRENT_DATE(), time_modified = CURRENT_TIME() WHERE ext = ?');
$dbh-execute($dbfile, $ext);

Re: Oracle functions through DBI?
Yes one can quite simply at least for a Stored procedure as for a function
you may have to wrap it in some SQL first.
my $db=;
my $db = DBI-connect();
my $desc = 'Comments from user ';
my $desc_out =;
my $sql=begin insert_comment(:p_id ,:p_desc,:p_desc_out); end;;
my $c=$db-prepare($sql) or die err 1 is $DBI::errstr\n;
$c-bind_param(:p_id,param('id')) or die err 2 is $DBI::errstr\n;
$c-bind_param_inout(:p_desc,\$desc,{ ora_type = ORA_CLOB }) or die err
3 is $DBI::errstr\n;
$c-bind_param_inout(:p_desc_out,\$desc_out,{ ora_type = ORA_CLOB }) or
die err 3 is $DBI::errstr\n;
$c-execute() or die err 4 is $DBI::errstr\n;
my $page_data = $c - fetchall_arrayref();
$c-finish();
print @$page_data;
print BRBR;
print $desc_out;
where my insert_comment stored Procedure starts like
CREATE procedure insert_comment(in_ID in NUMBER, in_log in out clob, out_log
in out clob )

I've tried a line identical to your:

works well for me, and appears to be the most compatible way of doing

Is last_insert_id() supposed to work in versions prior to 3.x? I know
it's only a relatively recent addition. That means that the code below
requires more checks on the version of DBD::mysql to see if
last_insert_id() is supported ( and working ).

This is definitely the behavior of MySQL, PostgreSQL, and Oracle,
and I'm pretty sure most others follow it as well.
And, can you omit the name of the column you want defaulted, and does this
server then insert the default value?
Yes. One way to think about this is to realize that *all* columns have
an automatic default of NULL, we are just changing it to something a
little more useful:
CREATE TABLE foo (
a int,
b int DEFAULT 22,
c int DEFAULT stockprice('RHAT')
);
is completely identical to:
CREATE TABLE foo (
a int DEFAULT NULL,
b int DEFAULT 22,
c int DEFAULT stockprice('RHAT')
);
