zeroDivisible / pgsql_recursive_query_example.sql
Created November 18, 2013 10:10
This is just an example pgSQL query. I don't have the exact schema right now, but basically, there was a tag (stored in table tags) which was mapping to parent (using parent_id) tag from the same table. Give a :startingTagId, this query returns a tag and all parents.
with recursive all_tags(rownum, id) as (
select 1::bigint, id, parent_id from tags where id = :startingTagId
union all
select rownum + 1, c.id, c.parent_id
from all_tags a
inner join tags c on a.parent_id = c.id)
select * from all_tags

zeroDivisible / tokenize.sql
Last active December 28, 2015 01:29
Function using plpgsql which tokenizes given word. As an example, for input ``word`` it returns ``word wor ord``
-- returns word divided into smaller tokens, not shorter than value specified in
-- MINIMUM_LENGTH.
--
-- calling this with param `bobcat` will return 'bobcat bob obc bca cat bobc obca bcat bobca obcat'
--
-- Please note that changing this function, especially the minimum length which it uses
-- means that each INDEX which depends on it needs to be recreated
create or replace function tokenize(varchar, integer, integer) returns varchar as
