Assignee: Francesco Chicchiriccò
> Find anytos using FIQL: SQL improvements
> ----------------------------------------
>
> Key: SYNCOPE-1502
> URL: https://issues.apache.org/jira/browse/SYNCOPE-1502
> Project: Syncope
> Issue Type: Improvement
> Components: core
> Affects Versions: 2.1.5
> Reporter: Dmitriy B.
> Assignee: Francesco Chicchiriccò
> Priority: Major
>
> PR contains improvements when AnyTOs are searched using FIQL queries:
> The resulted SQL query that finds any_to_keys can have a huge list with OR
> clauses for effective realms. This can be replaced to the IN clause.
> {code:sql}
> SELECT u.any_id,sv.username FROM (SELECT DISTINCT any_id FROM user_search
> WHERE (realm_id=? AND any_id IN ( SELECT DISTINCT any_id FROM user_search
> WHERE lastChangeDate<=?))) u,user_search sv WHERE u.any_id=sv.any_id AND
> u.any_id IN (SELECT any_id FROM user_search WHERE realm_id IN (SELECT id AS
> realm_id FROM Realm WHERE id=? OR id=? OR id=? OR id=? OR id=? OR id=? OR
> id=? OR id=? OR id=? OR id=? OR id=? OR id=? OR id=? OR id=? OR id=? OR id=?
> OR id=? OR id=? OR id=? OR id=? OR id=? OR id=? OR id=? OR id=? OR id=? OR
> id=? OR id=? OR id=? OR id=?)) ORDER BY sv.username ASC
> {code}
> When any tos are searched by keys a lot of single sql queries are executed.
> This can be improved using single SQL query with In clause.
