bool BTR_check_condition(Jrd::thread_db*, Jrd::index_desc*, Jrd::Record*);
Optimize creation of expression and partial indices (#7559) * Refactor index condition/expression evaluation into classes. Speed up (appr. 10x) creation and validation time for conditional indices. * Simplified NULL handling when index keys are composed * Refactor index key creation (from record). Optimize evaluation of index expressions. * Adjustments after Vlad's review * Remove redundant variables
2023-05-09 16:11:04 +02:00
dsc* BTR_eval_expression(Jrd::thread_db*, Jrd::index_desc*, Jrd::Record*);

2010-08-09 17:48:51 +02:00
void BTR_evaluate(Jrd::thread_db*, const Jrd::IndexRetrieval*, Jrd::RecordBitmap**, Jrd::RecordBitmap*);
Frontported improvement #7494 : Firebird performance issue - non necessary index reads. Also, fixed unregistered bug when scan of multi-segmented descending index with partial match and greater-than condition could miss some records.
2023-04-13 09:26:43 +02:00
UCHAR* BTR_find_leaf(Ods::btree_page*, Jrd::temporary_key*, UCHAR*, USHORT*, bool, int);

Ods::btree_page* BTR_find_page(Jrd::thread_db*, const Jrd::IndexRetrieval*, Jrd::win*, Jrd::index_desc*,
Better processing and optimization if IN <list> predicates (#7707) * WIP * Original (circa 2022) implementation of the IN LIST optimization, with some post-fixes and minor adjustments * Make it possible to optimize IN <list> for middle segments in compund indices * Avoid modifying the retrieval structure at runtime, it may be shared among concurrent requests * Simplify the code a little. Better cost calculation. Support both root-based and sibling-based list scans inside the same plan node. * Removed the unneeded const casts and other changed as suggested by Adriano
2023-09-04 08:13:10 +02:00

bool BTR_lookup(Jrd::thread_db*, Jrd::jrd_rel*, USHORT, Jrd::index_desc*, Jrd::RelationPages*);
Added missing (forgotten during refactoring) pre-sort before index scans. Fixed crash when all IN values are NULLs. Exclude duplicated IN values from the index scan.

Jrd::temporary_key*, Jrd::temporary_key*);
Make ExprNodes and RecordSourceNodes reference others directly instead of via jrd_nod. Store ValueExprNodes instead of jrd_nod in the metadata cache. Make RecordSourceNode child of ExprNode as they share most operations. Get rid of the JRD visitors in favor of direct calls. Convert assignments statement lists created inside expressions to separate source and targets ValuesExprNodes.
