问题 Good day everyone! I've got a graph. First, I know how to build simple recursive selections. I read some info on msdn . In this image you can see that (for example) the top node of the graph, which is numbered 0, influences node number 1 (etc (2->4), (3->4), (4->5), (5->6), (1->5)) TASK: for every node show nodes which it influences. For example, number 1 influences 5 and 6. The result SQL must return something like this: who_acts| on_whom_influence 0 | 1 0 | 5 0 | 6 1 | 5 1 | 6 2 | 4 2 | 5 2

问题 WITH x AS ( INSERT INTO users(name, age) SELECT 'john', 30 WHERE NOT EXISTS ( SELECT id FROM users WHERE name = 'john' ) u RETURNING (CASE WHEN u.id > 0 THEN u.id ELSE id END) ) SELECT * FROM x How can I always return an id and if the id is not present, then insert it.

问题 I am trying to write an application where there are files and users. The permissions for the files should be as in unix: read/write/execute. Each file belongs to a owner and a group, and for each file there are "other" users (based on who is owner, and who belongs to a group). The schema looks like this: create table s_file( file_id INTEGER PRIMARY KEY, parent_id INTEGER default NULL, name, content BLOB DEFAULT NULL, owner_id INTEGER NOT NULL, group_id INTEGER NOT NULL, read_owner BOOLEAN not
