unknown 4b0cce4873 BUG#17314: Can't use index_merge/intersection for MERGE tables ... 1. Fix index access costs for MERGE tables, set block_size=myisam_block_size/#underlying_tables instead of 0 which it was before. 2. Make index scans on MERGE table to return records in (key_tuple, merge_table_rowid) order, instead of just (key_tuple) order. This makes an index scan on MERGE table to be truly a ROR-scan which is a requirement for index_merge union/intersection. myisammrg/myrg_queue.c: BUG#17314: Make index scans on MERGE table return records ordered by (keytuple, merge_table_rowid). mysql-test/r/index_merge.result: Testcase for BUG#17314 mysql-test/r/merge.result: BUG#17314: update testcase result mysql-test/t/index_merge.test: Testcase for BUG#17314 sql/ha_myisammrg.cc: BUG#17314: For MERGE tables, set handler::block_size to myisam_block_size/#underlying_tables, and not to 0.		2006-02-11 21:51:43 +03:00
