A Python package to create simple SQL queries from the console, and quickly display the returned information.
Helper to consume a database from the REPL.
- Configuration file database.ini. A template is included in the source.
Full documentation available in https://github.com/sebasmonia/pyquebec/wiki
>>> from pyquebec import pyquebec >>> from pyquebec import formatters as pf >>> pyquebec.add('SampleDB', 'connection string here', 'MSSQL') # first use >>> db = pyquebec.open('SampleDB') # after using add, the db config and schema is cached >>> db.dbo.<TAB KEY> db.dbo.Table1 db.dbo.Table2 db.dbo.Table3 db.dbo.Table4 >>>result = db.dbo.Table1.From().go() >>> pf.to_html(result) Creating and opening temp file C:\Users\smonia\AppData\Local\Temp\tmpn3g43ppp.htm >>> pf.to_csv(result) Creating and opening temp file C:\Users\smonia\AppData\Local\Temp\tmpe68shxd9.csv >>> result row(column1=datetime.datetime(2015, 5, 13, 23, 34, 58, 77000), column2=59, column3=29, column4='Sample')
Pypyodbc returns tuples. This library converts them to namedtuples for increased readability and to make it easier to keep playing with the data using filter, map, sorted, etc.
There’s a third option in the formatters that uses tabulate for output to_console(). Both HTML and CSV options create a temp file and use os.startfile (in Windows you get the default browser and, usually, Excel).
Roadmap (help/guidance appreciated!):
- Tested with MSSQL and SQLite. With some configuration should support other engines, and ideally the config should be included in the package.
- The API for querying might need a few tweaks. Suggestions are welcome.
- Decide on other SQL features to support beyond basic querying. UPDATES, INSERTS, GROUP BY, etc, would it make sense? Would this make supporting other products more difficult?
- Needs more unittest!
