使用字典中的值作为Sqlite查询中的列标题

Question

I have an Sqlite database that I need to query from python.

The database only has two columns, "key" and "Value", and the value column contains a dictionary with multiple values. What I want to do is create a query to use some of those known dictionary keys as column headers, and the corresponding data under that column.

Is it possible to do that all in a query, or will I have to process the dictionary in python afterwards?

Example data (values obviously have been changed) that I want to query.

key                             |   Value
/auth/user_data/fb_me_user      | {"uid":"100008112345597","first_name":"Tim","last_name":"Robins","name":"Tim Robins","emails":["t.robins@gmail.com"]"}

There are lots of other key / value combinations, but this is one of the ones I am interested in.

I would like to query this to produce the following;

UID              |  Name        |   Email
100008112345597  |  Tim Robins  |   t.robins@gmail.com

Is that possible just in a query?

Thanks

Answer 1

after querying you get the value like below. from them you can get

value='''{"uid":"100008112345597","first_name":"Tim","last_name":"Robins","name":"Tim Robins","emails":["t.robins@gmail.com"]}'''

import ast
details=ast.literal_eval(value)
print details['uid'],details['name'],','.join(details['emails'])
