Current table is placed into read_tables set of the current join_tab->select so get_mm_parts function thinks that current table's record is read and tries to calculate WHERE condition with the fields of the record. Result of these calculations is unpredictable. Looks funny - outcome of the SELECT depends on the queries executed before. Anyway i think we should have testcase on this part of the code. mysql-test/r/sel000001.result: appropriate result added mysql-test/t/sel000001.test: testcase added sql/sql_select.cc: I think we should count current table out of read_tables set
