Here's the output of $ python fk_detect.py -h
$ python fk_detect.py -h
usage: fk_detect.py [-h] -t DBTYPE -H HOST -p PORT -u USER [--no-password]
[--password-file PASSWORD_FILE] [--ssl] [-d DB]
[-o OUTPUT] [-U]
Finds foreign keys in a database. This is accomplished with a combination of
using foreign key constraints and using column and table names. For example,
if a column is named user_id, and there is a table called user with an id
column, a foreign key will be reported.
optional arguments:
-h, --help show this help message and exit
-t DBTYPE, --dbtype DBTYPE
type of DB to connect to, valid values are "mysql" and
"postgres"
-H HOST, --host HOST host to connect to
-p PORT, --port PORT port to connect to
-u USER, --user USER user to connect with
--no-password connect without a password. otherwise provide
onethrough a file with --password-file
--password-file PASSWORD_FILE
location of a file that contains the password to the
database, see README.md for format
--ssl force the connection over SSL
-d DB, --db DB database to connect to (optional in MySQL)
-o OUTPUT, --output OUTPUT
output file, stdout is default
-U, --union-constraints
output proposed foreign keys unioned with known
foreign key constraints. By default fk_detect does not
output foreign keys represented as constraints in the
database. Enabling this switch will union them to the
proposed constraints.
Example, using Postgres:
$ python fk_detect -t postgres -H localhost -p 5432 -u user -d test_data --password-file password-file
Use a single line with nothing but the password in it, e.g., if your password is hunter2, the following file should be used:
hunter2
