Connecting to ODBC Databases from Python with pyodbcpyodbc is an open source Python module that provides access to ODBC databases. Python DB API 2. 0 specification. The Python DB API defines a database- neutral interface to data stored in relational databases. Python DB was designed to allow. This helps developers to write Python applications that are portable across databases. Python DB conformant module for ODBC databases. This tutorial shows how to use pyodbc with an ODBC driver, which you can download from this site. You can then connect Python on Linux and Unix to remote database such as Microsoft SQL Server, Oracle, DB2, Microsoft Access, Sybase ASE and Inter. Base. pyodbc and Linux. Easysoft ODBC drivers have been tested with pyodbc 2. Red. Hat, Ubuntu and Debian GNU/Linux, but should work with any recent 3. Linux distribution — Cent. OS, Fedora, Kubuntu, Mandrake/Mandriva, Open. Return to Chart. BagIt Library. Description: BagIt is a hierarchical file packaging format for storage and transfer of standardized digital packages called “bags”. SUSE/SUSE, Red. Hat Enterprise Linux (RHEL), Slackware and so on. Prerequisites. Python. The pyodbc module requires Python 2. README. txt, which is included with the pyodbc distribution). To build pyodbc, you need the Python libraries and header files, and a C++ compiler. When testing on Red. Kivy - Open source Python library for rapid development of applications that make use of innovative user interfaces, such as multi-touch apps. Potrace(TM) is a tool for tracing a bitmap, which means, transforming a bitmap into a smooth, scalable image. The input is a bitmap (PBM, PGM, PPM, or BMP format. Hat, we used Python 2. On Ubuntu, we used Python 2. Python 3. 2. 3, the python- dev package and the g++ package. ![]() ![]() On Debian, we used Python 2. ODBC Driver. To use pyodbc, you need to install an ODBC driver on the machine Python where is installed: Download the ODBC driver for your Python and database platform. Registration required.). For example, if want to access SQL Server from Python, download the Easysoft ODBC- SQL Server Driver for your Python platform. If the SQL Server ODBC driver is not currently available for your platform, check the list of ODBC- ODBC Bridge client platforms. The ODBC- ODBC Bridge is an alternative SQL Server solution from Easysoft, which you can download from this site. Install and license the ODBC driver on the machine where Python is installed. For installation instructions, see the ODBC driver documentation. Refer to the documentation to see which environment variables you need to set (LD_LIBRARY_PATH, LIBPATH, LD_RUN_PATH, SHLIB_PATH or ORACLE_HOME depending on the driver, platform and linker). Create a ODBC data source in /etc/odbc. For example, this SQL Server ODBC data source connects to a SQL Server Express instance that serves the Northwind database. MSSQL- PYTHON]. Driver = Easysoft ODBC- SQL Server. Server = my_machine\SQLEXPRESS. User = my_domain\my_user. Password = my_password. If the database you want to connect to is the default. SQL Server login, omit this attribute. Database = Northwind. Use isql to test the new data source. For example. cd /usr/local/easysoft/unix. ODBC/bin. ./isql - v MSSQL- PYTHONAt the prompt, type "help" to display a list of tables. To exit, press return in an empty prompt line. Installing pyodbc. On Unix and Linux platforms, you need to download the pyodbc source distribution and build it against an ODBC driver manager. These instructions show how to build pyodbc against the unix. ODBC driver manager supplied with an Easysoft ODBC driver. We recommend that you use the driver manager distributed with the driver because this is the version of unix. ODBC that we test the driver with. Download the source distribution from the pyodbc web site. Copy the distribution file to your Python machine, unzip and cd into the directory created by unzipping the file. For example. $ unzip pyodbc- 3. To build pyodbc against unix. ODBC, you need to tell the compiler and linker where to find the unix. ODBC include files and libraries. To do this, open setup. Wno- write- strings']Edit the line so that it looks likes this: settings['extra_compile_args'] = ['- Wno- write- strings','- I/usr/local/easysoft/unix. ODBC/include']Add the following line below the line you have just changed: settings['extra_link_args'] = ['- L/usr/local/easysoft/unix. ODBC/lib']Build pyodbc. Note To rebuild pyodbc, you may need to manually remove the build directory tree by using rm - r build rather than python setup. As root, install pyodbc. Run this command. UCS2'or'UCS4')"If the command’s output is UCS4 (as opposed to UCS2), refer to Using pyodbc with a UCS4 Python Build. Download the platform- independent source distribution from the pyodbc web site. Copy the distribution file to your Python machine, unzip and cd into the directory created by unzipping the file. For example. $ unzip pyodbc- 2. To build pyodbc against unix. ODBC, you need to tell the compiler and linker where to find the unix. ODBC include files and libraries. To do this, open setup. None. extra_link_args = None.

ODBC/lib']Note In pyodbc versions earlier than 2. PY. Build pyodbc. Note If you need to rebuild pyodbc, first remove the build directory tree by using rm - r build rather than python setup. When testing with pyodbc 2. As a consequence, running python setup. As root, install pyodbc. Run this command. UCS2'or'UCS4')"If the command’s output is UCS4 (as opposed to UCS2), refer to Using pyodbc with a UCS4 Python Build. Testing pyodbc. The pyodbc distribution includes two test suites: The Python DB API 2. Tests. The Python DB API 2. Python DB developers to verify their driver’s DB API conformance. As the tests access and manipulate database tables, they provide another way to test pyodbc against your ODBC driver and database. We therefore recommend that you run them. To do this: pyodbc 2. Run the tests. $ python tests/dbapitests. DSN=MSSQL- PYTHONpyodbc 2. Open setup. cfg in a text editor. In the [apitest] section, specify your ODBC data source in the connection- string value. For example. connection- string=DSN=MSSQL- PYTHONRun the tests. The pyodbc Tests. The pyodbc tests allow you to ensure that an ODBC driver is compatible with pyodbc. The pyodbc source code repository (http: //code. SQL Server. To run the SQL Server tests: Get a local copy of the pyodbc repository. Build pyodbc. Run the tests. DSN=MSSQL- PYTHONIf you are using Python 2. DSN=MSSQL- PYTHONThe pyodbc. Windows platforms. Note Some tests use data types and SQL syntax that are supported by SQL Server but not other databases. The test suite is most relevant to SQL Server therefore. The test suite does skip some tests based on data type information reported by the ODBC driver. However, some tests are still run even though the driver has reported that the prerequisite data type is not available. To see which tests pyodbctest skips, include the - d option when running the tests.)When we tested pyodbc, Easysoft ODBC drivers passed all tests that the target database was capable of passing. For example, when we ran the pyodbc test suite against Oracle Database XE, test_sqlserver_callproc failed because it uses SQL Server specific syntax to create and execute a stored procedure. If the test is modified to use SQL syntax that Oracle supports, the test succeeds. For example: # Recreate existing procedure using syntax that Oracle supports. IN OUT VARCHAR2) is begin select s into var. Call the procedure, using the more portable ODBC escape sequence.# The ODBC driver for the target database will replaces this escape# sequence with the appropriate DBMS- specific syntax for calling# procedures. This method for calling procedures will therefore work# for both Oracle and SQL Server.
