hi johan,

thanks a lot for your interesting post. so as i guess, expect the installation of additional modules, everything works perfect over this ODBC connection? well, in this case i will try to implement this solution with freetds and maybe come back to you if i need some help... if you want me to, of course.

regards,

patrick.

Betreff: Re: [otrs] OTRS connection over ODBC to MSSQL

Hi,

I've set up a connection to our MSSQL database using freetds. This should work. The only problem I still have, is that I cannot install any additional modules. I've already sent a mail around, but I didn't get much help except from Michiel. That mail contained the following information about the problem as I experience it:

After some communication with Michiel Beijen, I have to come back to the mailing list, cause he might have found the reason that it doesn't work in my case. When I put out a trace on the mssql server during the installation of a package, I have the following entry:

declare @p1 int

set @p1=15

exec sp_prepare @p1 output,N'@P1 varchar(80),@P2 varchar(80),@P3

varchar(80),@P4 varchar(80),@P5 varchar(80)',N'INSERT INTO

package_repository (name, version, vendor, filename, content_size,

content_type, content, install_status, create_time, create_by,

change_time, change_by) VALUES (@P1, @P2, @P3, @P4, ''213'', ''text/xml'',

@P5, ''not installed'', current_timestamp, 1, current_timestamp,

1)',1

select @p1

He thought that the problem might be caused in the following piece of code in Kernel/System/Package.pm:

   # add new package
   my $FileName = $Structure{Name}->{Content} . '-' .
$Structure{Version}->{Content} . '.xml';
   return $Self->{DBObject}->Do(
       SQL => 'INSERT INTO package_repository (name, version, vendor,
filename, '
           . ' content_size, content_type, content, install_status, '
           . ' create_time, create_by, change_time, change_by)'
           . ' VALUES (?, ?, ?, ?, \'213\', \'text/xml\', ?, \'not
installed\', '
           . ' current_timestamp, 1, current_timestamp, 1)',
       Bind => [
            \$Structure{Name}->{Content}, \$Structure{Version}->{Content},
           \$Structure{Vendor}->{Content}, \$FileName, \$Param{String},
       ],
   );
}

The problem as he told me, is that there are 5 values (the questionmarks) in the insert statement, from which only 4 are filled in the bind statement. In his database, the last value is a blob field with the contents of the module. I however can not check if this is the case in my database since I don't have any modules installed yet. Does anyone know how to solve this further?

Hello,
I would suggest googling for "mssql dbi"

I could find http://www.freeTDS.org People say they could make it work with Perl.

hi,

does anyone of you guys have experiences with an ODBC connection from an OTRS system that runs on a linux system to a MSSQL database? maybe you will ask, why the heck i want to connect to a MSSQL database as i have the possibility to you a MySQL database on the linux machine... well, we need a functionality that doesn't exist on MySQL so far i know...

thanks for some replies on this post.

regards,

patrick.
