2022-10-19
11:22
If a query uses an index where one or more of the columns of the index is an expression and if the corresponding expression is used elsewhere in the query, then strive to read the value of the expression out of the index, rather than recomputing it. This is the "Indexed Expression Optimizations". (check-in: 3da10328 user: drh tags: branch-3.28)
2022-09-27
17:00

2022-09-01
10:41
In the query planner, add a heuristic that will reduce the cost of a full table scan for a materialized view or subquery if the full scan is the outer-most loop. This is shown to speed up some queries. (check-in: e3754cc1 user: drh tags: branch-3.28)

In the WhereClause object, do not assume that all TERM_VIRTUAL terms appear at the end of the list, because that is no longer true. Instead, keep a separate nBase count that is the size of the list excluding the tail of virtual terms. Use nBase instead of nTerm when scanning terms that are not virtual. Add assert()s to validate correctness of WhereClause. (check-in: 6024682c user: drh tags: trunk)
