| 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]] | |
