Connecting to MSSQL db (PDO, FreeTDS, ODBC)

Question

I have an Ubuntu 12.04 server and I'm trying to establish a connection to a MSSQL database.

I've managed to connect using tsql and isql, but osql doesn't work and connecting with PHP using PDO also isn't working.. I will try to provide as much information as I can and if you need more just let me know and I will edit.

freetds.conf:

[MSSQL]
  host = TPSACC
  port = 54488
  tds version = 8.0

odbc.ini:

[MSSQL]
Description     = MS SQL connection to PRODUCTION database
Driver          = FreeTDS
Database        = PRODUCTION
Server          = TPSACC
UserName        = sa
Password        = pass
Trace           = No
TDS_Version     = 8.0
Port            = 54488

odbcinst.ini:

[FreeTDS]
Description = ODBC for Microsoft SQL
Driver      = /usr/local/lib/libtdsodbc.so
UsageCount  = 1
Threading   = 2

~> isql MSSQL sa pass

Server is "TPSACC"
osql: no IP address found for "TPSACC"

In PHP I have:

$conn = new PDO ("dblib:host=TPSACC;dbname=PRODUCTION","$username","$pw");

..or..

$conn = new PDO ("dblib:host=TPSACC;port=54488;dbname=PRODUCTION","$username","$pw");

And they both return this error:

SQLSTATE[HY000] Unable to connect: Adaptive Server is unavailable or does not exist (severity 9) 

I have been stuck here for a couple days and can't quite figure out why only half of the connections actually work..

Any and all help is really appreciated, thanks!

Solution

PHP modules installed?

Create a info.php file in your webserver (apache2 dir: /var/www/html in Ubuntu) with <?php phpinfo() ?> for view details. Use odbcinst -j for get config files loaded by unixODBC and tsql -C for get FreeTDS details; check if is MS db-lib source compatibility: yes.

If the MS db-lib is 'no' you need configure freetds with the --enable-msdblib.

My ./configure line:

./configure --with-tdsver=8.0 --with-unixodbc=/usr/local --enable-msdblib

Then sudo make && sudo make install

This is my working config:

Freetds.conf:

[MSSQL]
host = 192.168.1.200
port = 1433
tds version = 8.0
client charset = UTF-8

odbc.ini:

[mssql]
Description = MSSQL Server
Driver      = freetds #The odbcinst.ini driver name
ServerName  = MSSQL # The Freetds.conf connection name
Database    = database
TDS_Version = 8.0

odbcinst.ini

[freetds]
Description = MS SQL database access with Free TDS
Driver      = /usr/lib/libtdsodbc.so
Setup       = /usr/lib/x86_64-linux-gnu/odbclibtdsS.so
UsageCount  = 1

You're not using ODBC, with those connect strings. You're telling PHP to use the SQL Server-specific DBLIB connector, originally developed as Sybase (hence "Adaptive Server"). You may benefit from reviewing some documentation on PHP + ODBC. If you're targeting a recent SQL Server, you may also need a different ODBC driver, as FreeTDS doesn't yet fully support all the new features of SQL Server 2008 and later. My employer makes a few you can test for free.
