Connecting to MS-SQL server in Linux via Perl



  • I posted this over at PerlMonks and someone suggested posting it here.

    So here is the post:
     


    Hello,
    I am currently trying to connect to a MS-SQL server in Linux. I have
    using the Sybase method to connect, but recently ran into an issue with
    a different server.


    All of the previous servers have been straightforward, but this one has
    a slash in the name of the server. It is called ORCXPDB1C2\SQL. I add
    an additional slash in the server definition, but I am still having
    troubles connecting.

    Here is the connection information:

    use DBI;

    my $user = "xyz";

    my $passwd = "xyx2";

    my $server = "ORCXPDB1C2\SQL";

    my $dbh = DBI->connect("DBI:Sybase:server=$server", $user, $passwd, {PrintError => 0});



    If I connect to MS SQL servers without the slash, I can connect just
    fine with the above method. Not sure how to get around this issue.

    Thank you!


     



  • What is the error message being returned?



  • It is just getting to my die message since it is unable to connect.  I am trying to see if there are other methods to connect with \ in the server name.  So far, I am not having much luck.



  • Figured it out - change the connection string.  Remove the server distinction and put the full hostname and the port number.  I was able to connect and get my script to work properly.



  • unixODBC works well too, and lets you write to a more generic interface.



  • Does linux have a HOSTS file that lets you assign (mostly) arbitrary names to IP addresses?

    If so, you might consider removing the hard-coded IP address from the code and using a HOSTS entry.

    The Windows HOSTS file is named for /etc/hosts on unix systems. Modern linux platforms can do far more than just that.

     

    If so, you might consider removing the hard-coded IP address from the code and using a HOSTS entry.

    Or you could use a config file, or a DNS server, either of which is usually more sane. 



  • just a wild guess:



    my $server = "ORCXPDB1C2\SQL";

    my $dbh = DBI->connect("DBI:Sybase:server=$server", $user, $passwd, {PrintError => 0});

    Maybe the "DBI:Sybase:server=$server" becomes "DBI:Sybase:server=ORCXPDB1C2\SQL"

    On which the \S is an escape sequence? Try "ORCXPDB1C2\\SQL" as server string?

     

    (no perl experiance here :P just guessing)
