I have a web server which needs to link to a MS SQL server (not my choice). In my case I use Plack which calls the database in four steps. The catch I often struggle with is that some other files with the same name may float around and which you may not be aware off.

Run therefore a “find / -name odbc.ini” to double check this. Ditto for the others. Also check the proper location of the driver libtdsodbc.so and modify the path accordingly.

First ensure you installed the following modules using yum or apt-get

apt-get install odbc odbc-devel freetds-dev freetds-bin tdsodbc unixodbc

1. /home/user/path/config.yml
   This is the plack configuration file which you may skip and/or change should you use a different web server.

[..] plugins: Database: connections: sqlserver: dsn: ‘dbi:ODBC:DB_reference’ username: xxxx password: xxxx dbi_params: RaiseError: 1 AutoCommit: 1 PrintError: 1 LongReadLen: 102400 [..]

2. /etc/ODBC.ini

[DB_reference] Driver = FreeTDS Servername = DB_reference Port = 1433 Database = your_DB_name

3. /etc/ODBCinst.ini

[FreeTDS] Description = TDS driver (Sybase/MS SQL) Driver = /usr/lib/x86_64-linux-gnu/odbc/libtdsodbc.so Setup = /usr/lib/x86_64-linux-gnu/odbc/libtdsS.so CP Timeout = CPReuse =

4. /etc/freetds/freetds.conf

[global] tds version = 7.0 ; dump file = /tmp/freetds.log ; debug flags = 0xffff ; timeout = 10 ; connect timeout = 10 text size = 64512

[yourServerName] host = 192.168.x.x port = 1433 client charset = UTF-8
