(This is due to ticket [2f7170d73bf9abf80] ** from 2015-02-09.) ** ** (3) If the subquery is the right operand of a LEFT JOIN then ** (3a) the subquery may not be a join and ** (3b) the FROM clause of the subquery may not contain a virtual ** table and ** (3c) the outer query may not be an aggregate. ** ** (4) The subquery can not be DISTINCT. ** ** (**) At one point restrictions (4) and (5) defined a subset of DISTINCT ** sub-queries that were excluded from this optimization. Restriction ** (4) has since been expanded to exclude all DISTINCT subqueries. ** ** (**) We no longer attempt to flatten aggregate subqueries.

TODO: For subqueries without ** A FROM clause, consider adding a FROM clause with the special ** table sqlite_once that consists of a single row containing a ** single NULL. ** ** (8) If the subquery uses LIMIT then the outer query may not be a join. ** ** (9) If the subquery uses LIMIT then the outer query may not be aggregate. ** ** (**) Restriction (10) was removed from the code on 2005-02-05 but we ** accidently carried the comment forward until 2014-09-15. Original ** constraint: "If the subquery is aggregate then the outer query ** may not use LIMIT." ** ** (11) The subquery and the outer query may not both have ORDER BY clauses. ** ** (**) Not implemented. Subsumed into restriction (3). Was previously ** a separate restriction deriving from ticket #350. ** ** (13) The subquery and outer query may not both use LIMIT. ** ** (14) The subquery may not use OFFSET. ** ** (15) If the outer query is part of a compound select, then the ** subquery may not use LIMIT. ** (See ticket #2339 and ticket [02a8e81d44]). ** ** (16) If the outer query is aggregate, then the subquery may not ** use ORDER BY. (Ticket #2942) This used to not matter ** until we introduced the group_concat() function. ** ** (17) If the subquery is a compound select, then ** (17a) all compound operators must be a UNION ALL, and ** (17b) no terms within the subquery compound may be aggregate ** or DISTINCT, and ** (17c) every term within the subquery compound must have a FROM clause ** (17d) the outer query may not be ** (17d1) aggregate, or ** (17d2) DISTINCT, or ** (17d3) a join. ** ** The parent and sub-query may contain WHERE clauses. Subject to ** rules (11), (13) and (14), they may also contain ORDER BY, ** LIMIT and OFFSET clauses. The subquery cannot use any compound ** operator other than UNION ALL because all the other compound ** operators have an implied DISTINCT which is disallowed by ** restriction (4). ** ** Also, each component of the sub-query must return the same number ** of result columns. This is actually a requirement for any compound ** SELECT statement, but all the code here does is make sure that no ** such (illegal) sub-query is flattened. The caller will detect the ** syntax error and return a detailed message. ** ** (18) If the sub-query is a compound select, then all terms of the ** ORDER BY clause of the parent must be simple references to ** columns of the sub-query. ** ** (19) If the subquery uses LIMIT then the outer query may not ** have a WHERE clause. ** ** (**) Subsumed into (17d3). Was: If the sub-query is a compound select, ** then it must not use an ORDER BY clause - Ticket #3773. Because ** of (17d3), then only way to have a compound subquery is if it is ** the only term in the FROM clause of the outer query. But if the ** only term in the FROM clause has an ORDER BY, then it will be ** implemented as a co-routine and the flattener will never be called. ** ** (21) If the subquery uses LIMIT then the outer query may not be ** DISTINCT. (See ticket [752e1646fc]). ** ** (22) The subquery may not be a recursive CTE. ** ** (**) Subsumed into restriction (17d3). Was: If the outer query is ** a recursive CTE, then the sub-query may not be a compound query. ** This restriction is because transforming the ** parent to a compound query confuses the code that handles ** recursive queries in multiSelect(). ** ** (**) We no longer attempt to flatten aggregate subqueries. Was: ** The subquery may not be an aggregate that uses the built-in min() or ** or max() functions.
