schemainspect: SQL Schema Inspection

Schema inspection for PostgreSQL (and potentially others in the future).

Inspects tables, views, materialized views, constraints, indexes, sequences, enums, functions, and extensions. Handles table partitioning and inheritance.

Limitations: Function inspection only confirmed to work with SQL/PLPGSQL languages so far.

Basic Usage

Get an inspection object from an already opened SQLAlchemy session or connection as follows:

from schemainspect import get_inspector
from sqlbag import S

with S('postgresql:///example') as s:
    i = get_inspector(s)

The inspection object has attributes for tables, views, and all the other things it tracks. At each of these attributes you'll find a dictionary (OrderedDict) mapping from fully-qualified-and-quoted-name-of-thing-in-database to information object.

For instance, the information about a table books would be accessed as follows:

>>> books_table = i.tables['"public"."books"']
>>> books_table.name
'books'
>>> books_table.schema
'public'
>>> [each.name for each in books_table.columns]
['id', 'title', 'isbn']

Documentation

Documentation is a bit patchy at the moment. Watch this space!
