PHP PDO_mssql SQLSTATE[01002] Adaptive Server connection failed (severity 9)

Question

I'm connecting to external MSSQL database for exports from PHP55/osx and I have wierd issue.

code:

new \PDO("dblib:host={$hostname};dbname={$dbname}", $user, $pass);

throws:

SQLSTATE[01002] Adaptive Server connection failed (severity 9)

but connection from CLI works correcty

tsql -S hostname -U user -P pass -L dbname:

locale is "cs_CZ.UTF-8"
locale charset is "UTF-8"
using default charset "UTF-8"
1> 

freetds.conf:

[hostname]
    host = ipaddress
    port = 1433
    tds version = 8.0

tsql -C:

                        Version: freetds v0.91
         freetds.conf directory: /usr/local/Cellar/freetds/0.91/etc
 MS db-lib source compatibility: no
    Sybase binary compatibility: no
                  Thread safety: yes
                  iconv library: yes
                    TDS version: 7.1
                          iODBC: no
                       unixodbc: no
          SSPI "trusted" logins: no
                       Kerberos: no

Any ideas? I have tried alomost anything, connect to hostname, ip, with and without port, to instance name, another user, TDS versions 7.0,7.1,7.2,8.0, reinstall php and freetds

Answer 1

Check these:

1. locate freetds.conf on your disk. It is possible it exists in several places and tsql uses one while PHP used another one. Best is to symlink them into one common file and test on that. Note that a common place for that file is ~/.freetds.conf beside /etc/ or /usr/local/etc/

2. there should be a [global] section on your freetds.conf file. Put there these lines :

   tds version = 8.0

   text size = 20971520

   client charset = UTF-8

Of course, I expect that you already checked which driver is loaded by PHP with phpinfo(): mssql, sqlsrv or dblib

Answer 2

This is the generic failure message. You cannot connect to the database for whatever reason. Given you use OSX and brew most likely the problem lies in linking/loading the shared library. FreeTDS is based on Sybase 8 (as is MS SQL Server). It is a bit arcane to compile with.

Was your PHP linked against the libsybdb.dylib that brew installs? You should be able to find out using phpinfo() if this is included in your server:

Configure Command '--with-pdo-dblib=shared,/usr/local/Cellar/freetds/0.91/lib'

To get it to work you need to compile/build your PHP with the dblib option.

Answer 3

My solution:

Get FreeTds

• brew install freetds
• copy everything in the lib/ folder of your freetds installation into the lib/ folder of your PHP installation directory, replacing the old versions of: libct.4.dylib, libct.a, libct.dylib, libsybdb.5.dylib, libsybdb.a, libsybdb.dylib

Compile and install the dblib extension

• download the php source for whatever php version you have installed
• navigate to the ext/pdo_dblib subfolder of the source
• run phpize, making sure it is the correct binary for your installation
• run the configure command with e.g. parameters: ./configure --with-php-config=/usr/local/php5/bin/php-config --with-pdo-dblib=/usr/local/Cellar/freetds/0.95.19/
• run make
• copy modules/pdo_dblib.so into your PHP installation directory, replacing the old version
