ODBC Driver for SQL Server

Build 20.0.7587

Linux DSN Configuration

This section describes how to set up ODBC connectivity and configure DSNs on several Linux distributions: Debian-based systems, like Ubuntu, and Red Hat Linux platforms, like Red Hat Enterprise Linux (RHEL), CentOS, and Fedora.

Minimum Linux Versions

Here are the minimum supported versions for Red Hat-based and Debian-based systems:

OSMin. Version
Ubuntu11.04
Debian7
RHEL6.9
CentOS6.9
Fedora13
SUSE12.1

Installing the Driver Dependencies

Run the following commands as root or with sudo to install the necessary dependencies:

  • Debian/Ubuntu:
    apt-get install libc6 libstdc++6 zlib1g libgcc1
  • RHEL/CentOS/Fedora:
    yum install glibc libstdc++ zlib libgcc

Here are the corresponding libraries required by the driver:

Debian/Ubuntu PackageRHEL/CentOS/Fedora PackageFile
libc6glibclinux-vdso.1
libc6glibclibm.so.6
libc6glibclibrt.so.1
libc6glibclibdl.so.2
libc6glibclibpthread.so.0
libc6glibclibc.so.6
libc6glibcld-linux-x86-64.so.2
libstdc++6libstdc++libstdc++.so.6
zlib1gzliblibz.so.1
libgcc1libgcclibgcc_s.so.1

Installing the Driver

You can use standard package management systems to install the driver.

On Debian-based systems, like Ubuntu, run the following command with root or sudo:

dpkg -i /path/to/driver/setup/SQLODBCDriverforUnix.deb 

On systems that support the RPM package format, run the following command with root or sudo:

rpm -ivh /path/to/driver/SQLODBCDriverforUnix.rpm 

Licensing the Driver

Run the following commands to license the driver. To activate a trial, omit the <key> input.

cd /opt/cdata/cdata-odbc-driver-for-sql/bin/
sudo ./install-license.x64 <key>

Connecting through the Driver Manager

The driver manager loads the driver and passes function calls from the application to the driver. You need to register the driver with the driver manager and you define DSNs in the driver manager's configuration files.

The driver installation registers the driver with the unixODBC driver manager and creates a system DSN. The unixODBC driver manager can be used from Python and from many other applications. Your application may embed another driver manager.

Creating the DSN

See Using unixODBC to install unixODBC and configure DSNs. See Using the DataDirect Driver Manager to create a DSN to connect to OBIEE, Informatica, and SAS.

You can use the CData ODBC Driver for SQL Server to connect to any instance of Microsoft SQL Server, Azure SQL Server, or Azure Data Warehouse.

Authenticating to Microsoft SQL Server

You can authenticate to SQL Server using either standard or Kerberos authentication.

Authenticate using Standard Authentication

To authenticate to Microsoft SQL Server using standard authentication, set the following:

  • User: The username provided for authentication with SQL Server.
  • Password: The password associated with the authenticating user.

Authenticate using Kerberos Authentication

To authenticate to Microsoft SQL Server using Kerberos authentication, set the following:

  • AuthScheme: Set this to kerberos to enable Kerberos authentication.
  • KerberosKDC: The Kerberos Key Distribution Center (KDC) service used to authenticate the user.
  • KerberosRealm: The Kerberos Realm used to authenticate the user with.
  • KerberosSPN: The Service Principal Name for the Kerberos Domain Controller.
  • User: The username provided for authentication with SQL Server.
  • Password: The password associated with the authenticating user.

Connecting to Microsoft SQL Server

Once you've configured all requirede authentication properties, connect to Microsoft SQL Server using the following:

  • Server: The name of the server running SQL Server.
  • Database: The name of the SQL Server database.

Connecting to Azure SQL Server and Azure Data Warehouse

You can authenticate to Azure SQL Server or Azure Data Warehouse by setting the following connection properties:

  • Server: The server running Azure. You can find this by logging into the Azure portal and navigating to SQL databases (or SQL data warehouses) -> Select your database -> Overview -> Server name.
  • User: The name of the user authenticating to Azure.
  • Password: The password associated with the authenticating user.
  • Database: The name of the database, as seen in the Azure portal on the SQL databases (or SQL warehouses) page.

Set the Driver Encoding

The ODBC drivers need to specify which encoding to use with the ODBC Driver Manager. By default, the CData ODBC Drivers for Unix are configured to use UTF-16 which is compatible with unixODBC, but other Driver Managers may require alternative encoding.

Alternatively, if you are using the ODBC driver from an application that uses the ANSI ODBC API it may be necessary to set the ANSI code page. For example, to import Japanese characters in an ANSI application, you can specify the code page in the config file '/opt/cdata/cdata-odbc-driver-for-sql/lib/cdata.odbc.sql.ini':

[Driver]
AnsiCodePage = 932
