Something like this? Your seed number will go into the values statement at the start.
with recursive foo (A_id) as ( values (1) union select A.A_id from foo inner join A on foo.A_id = A.object_id where A.A_id is not null ) select distinct B.data from foo inner join A on foo.A_id = A.object_id inner join B on A.B_id = B.object_id; -----Original Message----- From: sqlite-users [mailto:sqlite-users-boun...@mailinglists.sqlite.org] On Behalf Of MM Sent: Friday, June 15, 2018 9:19 AM To: SQLite mailing list Subject: [sqlite] Recursive query I have table A of rows with column "object_id", and 2 NULL columns A_id and B_id. Each row of A (among rows with the same object_id) either references table A itself or table B, ie columns A_id and B_id are mutually exclusive. e.g. Table A object_id A_id B_id ... 1 NULL 5 1 3 NULL 1 NULL 7 3 NULL 2 3 NULL 3 ... Table B object_id data ... 2 15 3 16 5 17 7 18 ... My objective is to collect all unique "data" in all the B rows that belong to a given A object_id (like '1') and all its "descendants". For e.g.: given object "1", the result of the query would be the list 17, 18. 15, 16 in no particular order given object "3", the result of the query would be the list 15 16 Can this be done with a recursive cet query? If so, how?
