- Project
- -------
- adodbapi
-
- A Python DB-API 2.0 (PEP-249) module that makes it easy to use Microsoft ADO
- for connecting with databases and other data sources
- using either CPython or IronPython.
-
- Home page: <http://sourceforge.net/projects/adodbapi>
-
- Features:
- * 100% DB-API 2.0 (PEP-249) compliant (including most extensions and recommendations).
- * Includes pyunit testcases that describe how to use the module.
- * Fully implemented in Python. -- runs in Python 2.5+ Python 3.0+ and IronPython 2.6+
- * Licensed under the LGPL license, which means that it can be used freely even in commercial programs subject to certain restrictions.
- * The user can choose between paramstyles: 'qmark' 'named' 'format' 'pyformat' 'dynamic'
- * Supports data retrieval by column name e.g.:
- for row in myCurser.execute("select name,age from students"):
- print("Student", row.name, "is", row.age, "years old.")
- * Supports user-definable system-to-Python data conversion functions (selected by ADO data type, or by column)
-
- Prerequisites:
- * C Python 2.7 or 3.5 or higher
- and pywin32 (Mark Hammond's python for windows extensions.)
- or
- Iron Python 2.7 or higher. (works in IPy2.0 for all data types except BUFFER)
-
- Installation:
- * (C-Python on Windows): Install pywin32 ("pip install pywin32") which includes adodbapi.
- * (IronPython on Windows): Download adodbapi from http://sf.net/projects/adodbapi. Unpack the zip.
- Open a command window as an administrator. CD to the folder containing the unzipped files.
- Run "setup.py install" using the IronPython of your choice.
-
- NOTE: ...........
- If you do not like the new default operation of returning Numeric columns as decimal.Decimal,
- you can select other options by the user defined conversion feature.
- Try:
- adodbapi.apibase.variantConversions[adodbapi.ado_consts.adNumeric] = adodbapi.apibase.cvtString
- or:
- adodbapi.apibase.variantConversions[adodbapi.ado_consts.adNumeric] = adodbapi.apibase.cvtFloat
- or:
- adodbapi.apibase.variantConversions[adodbapi.ado_consts.adNumeric] = write_your_own_convertion_function
- ............
- notes for 2.6.2:
- The definitive source has been moved to https://github.com/mhammond/pywin32/tree/master/adodbapi.
- Remote has proven too hard to configure and test with Pyro4. I am moving it to unsupported status
- until I can change to a different connection method.
- whats new in version 2.6
- A cursor.prepare() method and support for prepared SQL statements.
- Lots of refactoring, especially of the Remote and Server modules (still to be treated as Beta code).
- The quick start document 'quick_reference.odt' will export as a nice-looking pdf.
- Added paramstyles 'pyformat' and 'dynamic'. If your 'paramstyle' is 'named' you _must_ pass a dictionary of
- parameters to your .execute() method. If your 'paramstyle' is 'format' 'pyformat' or 'dynamic', you _may_
- pass a dictionary of parameters -- provided your SQL operation string is formatted correctly.
-
- whats new in version 2.5
- Remote module: (works on Linux!) allows a Windows computer to serve ADO databases via PyRO
- Server module: PyRO server for ADO. Run using a command like= C:>python -m adodbapi.server
- (server has simple connection string macros: is64bit, getuser, sql_provider, auto_security)
- Brief documentation included. See adodbapi/examples folder adodbapi.rtf
- New connection method conn.get_table_names() --> list of names of tables in database
-
- Vastly refactored. Data conversion things have been moved to the new adodbapi.apibase module.
- Many former module-level attributes are now class attributes. (Should be more thread-safe)
- Connection objects are now context managers for transactions and will commit or rollback.
- Cursor objects are context managers and will automatically close themselves.
- Autocommit can be switched on and off.
- Keyword and positional arguments on the connect() method work as documented in PEP 249.
- Keyword arguments from the connect call can be formatted into the connection string.
- New keyword arguments defined, such as: autocommit, paramstyle, remote_proxy, remote_port.
- *** Breaking change: variantConversion lookups are simplified: the following will raise KeyError:
- oldconverter=adodbapi.variantConversions[adodbapi.adoStringTypes]
- Refactor as: oldconverter=adodbapi.variantConversions[adodbapi.adoStringTypes[0]]
