I'm getting the error above when issuing

 isql 'odbc:Driver={ODBC Driver 11 for SQL Server};SERVER=<redacted>;DATABASE=<redacted>;' username password -v

as root on my Linux CentOS 6.7.

The following bcp command works, so the driver should be working correctly:

bcp master.INFORMATION_SCHEMA.TABLES out OutFile.dat -S <redacted> -U user -P password

Also this command works:

sqlcmd -Sg<redacted> -Uuser -Ppassword

Also this PHP script, if run from command line as root, will return an error:

$connStr = 'odbc:Driver={ODBC Driver 11 for SQL Server};SERVER=<redacted>;DATABASE=<redacted>;';
$dbUser = '<redacted>';
$dbPass = '<redacted>';

$db = new PDO($connStr, $dbUser, $dbPass);

[root@ru000397 ~]# php prova.php
PHP Fatal error:  Uncaught exception 'PDOException' with message 'could not find driver' in /root/prova.php:6

I already installed Microsoft ODBC Driver 11 for SQL Server for Linux (https://msdn.microsoft.com/library/hh568451(SQL.110).aspx) and unixODBC 2.3.0 without issues.

My main goal is to be able to connect to MS SQL instance via PHP PDO using ODBC.


The PDO connection couldn't find the driver for me when using the curly braces. After removing those, I was able to connect just fine.

Note my usage of the double quotes for the connection string which allows variable expansion.

$mssqldriver = 'ODBC Driver 11 for SQL Server';
$connStr = "odbc:Driver=$mssqldriver;SERVER=<redacted>;DATABASE=<redacted>;";
