Requirements

PostgreSQL 9.1+ with Multicorn extension installed.

If you haven't used Multicorn yet, enable it with:

create extension multicorn;

From source:

git clone https://github.com/TheDeadJoe/google_spreadsheets_fdw
cd google_spreadsheets_fdw
python setup.py install

Usage

create server multicorn_srv foreign data wrapper multicorn options (
    wrapper 'google_spreadsheets_fdw.GoogleSpreadsheetFDW'
);

create foreign table my_table (
    id int default nextval('my_seq'),
    foo varchar,
    bar int,
    baz float
) server multicorn_srv options (
    gskey 'zVshdGDuaQKKaQoXqNOwjeTWcxcUtOlSJDZoLeIMUsYx',
    keyfile '/path/to/credentials.json',
    sheet '0',
    row_id 'id'
);

Options

• gskey - "ID" of a spreadsheet (the 44 char length part between /spreadsheets/d/ and /edit/ from spreadsheet URL)
• keyfile - path to Google Cloud Services credentials json file
• sheet - index of a sheet
• row_id - name of the column which value will be treated as an ID of the whole row

Example

We start with an empty spreadsheet:

Let's insert some data into it:

insert into my_table(foo, bar, baz) values ('a', 1, 0.1);
insert into my_table(foo, bar, baz) values ('b', 2, 0.2);
insert into my_table(foo, bar, baz) values ('c', 3, 0.3);
insert into my_table(baz, bar, foo) values (0.4, 4, 'd') returning *;

Spreadsheet contains our data.

Now let's try retrieve the data:

select * from my_table;

The result:

Of course, we can also perform other SQL operations e.g.:

update my_table set bar = 9, baz = 0.9 where bar = 2;

delete from my_table where bar > 5;
