SQLite list ALL foreign keys in a database

It seems that all (or many) of the PRAGMA commands can be programatically selected with a little trick;

Usually the are called like:

PRAGMA table_info('my_table');
PRAGMA foreign_key_list('my_table');

But this can also be done:

SELECT * FROM pragma_table_info('my_table');
SELECT * FROM pragma_foreign_key_list('my_table');

And the schema can also be (more or less) obtained:

.schema pragma_table_info
/* pragma_table_info(cid,name,type,"notnull",dflt_value,pk) */;

.schema pragma_foreign_key_list
/* pragma_foreign_key_list(id,seq,"table","from","to",on_update,on_delete,"match") */

So, to get all the fks a JOIN between sqlite_master and pragma_foreign_key_list can do the trick:

SELECT 
    m.name
    , p.*
FROM
    sqlite_master m
    JOIN pragma_foreign_key_list(m.name) p ON m.name != p."table"
WHERE m.type="table"
ORDER BY m.name
;

Just take care, that some fields of pragma_foreign_key_list like table, from, … must be quoted;
