Looking for good documentation of odbc.ini and odbcinst.ini files on Linux

I use FreeTDS on Debian to connect a php-driven website to a MS-SQL Server 2005 Database.

The explanation I can give to the config files:


Holds the instance that is referred to within the handler (e.g. php) that connects to the database (see example below). The configuration defines the server it needs to connect to.

Driver          =       FreeTDS
Description     =       test
Database        =       MyCompanyDb
Server          =       frodo
Readonly        =       Yes
Port            =       1433
Trace           =       No


Holds the configuration for the Driver section in odbc.ini.

Description     = TDS connection
Driver          = /usr/lib/odbc/libtdsodbc.so
Setup           = /usr/lib/odbc/libtdsS.so
UsageCount      = 1
FileUsage       = 1
Trace           = Yes
TraceFile       = /tmp/odbcinst_tr


Example php code to demonstrate how I set up and use the connection.

  $conn_id = odbc_connect($host, $user ,$password) or die (odbc_errormsg());

  $sql_companies =  "SELECT * from AMGR_Client_Tbl WHERE Record_Type="1"";

  $query_companies = odbc_exec($conn_id, $sql_companies);
  while (odbc_fetch_row($query_companies))
    $client_id     = odbc_result($query_companies, 6);
    $company_name  = odbc_result($query_companies, 9);

etc.. etc..

I’m sure there’s many other variables that can be set and used but this is the simplest explanation I can give of the files you asked about.
