Squeak
Python helper for sqlite3. Allows to drop & alter columns.
Installation
Squeak is contained in a single python file. Just download http://teebes.com/squeak.py into the directory of your choice and either run the file as a python executable or add it to your Python path.
If you'd like to get the git archive and build from source you can do:
$ git clone git://github.com/teebes/squeak.git $ cd squeak $ python setup.py install
Or, if you have pip, you can install with:
$ pip install git://github.com/teebes/squeak.git#egg=squeak
Usage
Sample usage for a sqlite3 database 'db' with the following table:
- CREATE TABLE "my_table" (
- "id" integer NOT NULL PRIMARY KEY, "name" varchar (20) NOT NULL DEFAULT ""
);
Examples from the command line
To drop the 'name' column:
$ squeak.py db my_table drop_column name
To rename the 'name' column to 'first_name':
$ squeak.py db my_table rename_column name first_name
To allow the 'name' column to be null:
$ squeak.py db my_table replace_definition name varchar \(20\)
Same examples from the python shell
To drop the 'name' column:
>>> from squeak import Squeak
>>> s = Squeak('db', 'my_table')
>>> s.drop_column('name')
To rename the 'name' column to 'first_name':
>>> from squeak import Squeak
>>> s = Squeak('db', 'my_table')
>>> s.drop_column('name')
To allow the 'name' column to be null:
>>> from squeak import Squeak
>>> s = Squeak('db', 'my_table')
>>> s.replace_definition('name', 'varchar (20)')
Tests
Squeak comes with a few unit tests. Just execute tests.py to run the suite.
