pymysql fetchall() results as dictionary?

Question

Is there any way to get the results from a fetchall() as a dictionary using pymysql?

Answer 1

Use pymysql.cursors.DictCursor, which will return rows represented as dictionaries mapping column names to values.

A few ways to use it...

Create a connection object and have all cursors spawned from it be DictCursors:

>>> import pymysql
>>> connection = pymysql.connect(db='foo', cursorclass=pymysql.cursors.DictCursor)
>>> with connection.cursor() as cursor:
...     print cursor
... 

>>> with connection.cursor() as cursor:
...     cursor.execute("SELECT * FROM bar")
...     print cursor.fetchall()
... 
2
[{u'col2': 'rty', u'col1': 'qwe'}, {u'col2': 'fgh', u'col1': 'asd'}]

Create a DictCursor from an ordinary connection object:

>>> connection = pymysql.connect(db='foo')
>>> with connection.cursor(pymysql.cursors.DictCursor) as cursor:
...     print cursor
... 

Connect and create a DictCursor in one line with with:

>>> from pymysql.cursors import DictCursor
>>> with pymysql.connect(db='foo', cursorclass=DictCursor) as cursor:
...     print cursor
...
