Igor Babaev	2b1f0b8757	Back-ported the patch of the mysql-5.6 code line that fixed several defects in the greedy optimization: 1) The greedy optimizer calculated the 'compare-cost' (CPU-cost) for iterating over the partial plan result at each level in the query plan as 'record_count / (double) TIME_FOR_COMPARE' This cost was only used locally for 'best' calculation at each level, and not accumulated into the total cost for the query plan. This fix added the 'CPU-cost' of processing 'current_record_count' records at each level to 'current_read_time' before it is used as 'accumulated cost' argument to recursive best_extension_by_limited_search() calls. This ensured that the cost of a huge join-fanout early in the QEP was correctly reflected in the cost of the final QEP. To get identical cost for a 'best' optimized query and a straight_join with the same join order, the same change was also applied to optimize_straight_join() and get_partial_join_cost() 2) Furthermore to get equal cost for 'best' optimized query and a straight_join the new code substrcated the same '0.001' in optimize_straight_join() as it had been already done in best_extension_by_limited_search() 3) When best_extension_by_limited_search() aggregated the 'best' plan a plan was 'best' by the check : 'if ((search_depth == 1) \|\| (current_read_time < join->best_read))' The term '(search_depth == 1' incorrectly caused a new best plan to be collected whenever the specified 'search_depth' was reached - even if this partial query plan was more expensive than what we had already found.	14 years ago

Michael Widenius	6a9ac86cd3	Fix for bug lp:798597 Incorrect "Duplicate entry" error with views and GROUP BY mysql-test/r/join.result: Test case for LP:798597 mysql-test/t/join.test: Test case for LP:798597 sql/sql_select.cc: In simplify_joins we reset table->maybe_null for outer join tables that can't ever be NULL. This caused a conflict between the previously calculated items and the group_buffer against the fields in the temporary table that are created as not null thanks to the optimization. The fix is to correct the group by items to also be not_null so that they match the used fields and keys.	15 years ago

Igor Babaev	21b1b5f040	Fixed bug #52636 . Applied the fix for bug #47217 from the mysql-6.0 codebase. The patch adds not null predicates generated for the left parts of the equality predicates used for ref accesses. This is done for such predicates both in where conditions and on conditions. For the where conditions the not null predicates were generated but in 5.0/5.1 they actually never were used due to some lame merge from 4.1 to 5.0. The fix for bug #47217 made these predicates to be used in the condition pushed to the tables. Yet only this patch generates not null predicates for equality predicated from on conditions of outer joins. This patch introduces a performance regression that can be observed on a test case from null_key.test. The regression will disappear after the fix for bug #57024 from mariadb-5.1 is pulled into mariadb-5.3. The patch contains many changes in the outputs of the EXPLAIN commands since generated not null predicates are considered as parts of the conditions pushed to join tables and may add 'Usingwhere' in some rows of EXPLAINs where there used to be no such comments.	15 years ago

Alexey Kopytov	6cf49743e8	Bug #53544 : Server hangs during JOIN query in stored procedure called twice in a row Queries with nested joins could cause an infinite loop in the server when used from SP/PS. When flattening nested joins, simplify_joins() tracks if the name resolution list needs to be updated by setting fix_name_res to TRUE if the current loop iteration has done any transformations to the join table list. The problem was that the flag was not reset before the next loop iteration leading to unnecessary "fixing" of the name resolution list which in turn could lead to a loop (i.e. circularly-linked part) in that list. This was causing problems on subsequent execution when used together with stored procedures or prepared statements. Fixed by making sure fix_name_res is reset on every loop iteration. mysql-test/r/join.result: Added a test case for bug #53544. mysql-test/t/join.test: Added a test case for bug #53544. sql/sql_select.cc: Make sure fix_name_res is reset on every loop iteration.	15 years ago
Alexey Kopytov	cd4ca4b7a3	Bug #55568 : user variable assignments crash server when used within query The server could crash after materializing a derived table which requires a temporary table for grouping. When destroying the temporary table used to execute a query for a derived table, JOIN::destroy() did not clean up Item_fields pointing to fields in the temporary table. This led to dereferencing a dangling pointer when printing out the items tree later in the outer SELECT. The solution is an addendum to the patch for bug37362: in addition to cleaning up items in tmp_all_fields3, do the same for items in tmp_all_fields1, since now we have an example where this is necessary. mysql-test/r/join.result: Added test cases for bug#55568 and a duplicate bug #54468. mysql-test/t/join.test: Added test cases for bug#55568 and a duplicate bug #54468. sql/field.cc: Make sure field->table_name is not set to NULL in Field::make_field() to avoid assertion failure in Item_field::make_field() after cleaning up items (the assertion fired in udf.test when running the test suite with the patch applied). sql/sql_select.cc: In addition to cleaning up items in tmp_all_fields3, do the same for items in tmp_all_fields1.

Alexey Kopytov	6d43510a42	Backport of the fix for bug #50335 to 5.0. The problem was in an incorrect debug assertion. The expression used in the failing assertion states that when finding references matching ORDER BY expressions, there can be only one reference to a single table. But that does not make any sense, all test cases for this bug are valid examples with multiple identical WHERE expressions referencing the same table which are also present in the ORDER BY list. Fixed by removing the failing assertion. We also have to take care of the 'found' counter so that we count multiple references only once. We rely on this fact later in eq_ref_table(). mysql-test/r/join.result: Added a test case for bug #50335. mysql-test/t/join.test: Added a test case for bug #50335. sql/sql_select.cc: Removing the assertion in eq_ref_table() as it does not make any sense.

Sergey Glukhov	f57839cd60	Bug#52177 crash with explain, row comparison, join, text field The crash is the result of an attempt made by JOIN::optimize to evaluate the WHERE condition when no records have been actually read.

Sergey Glukhov	bccf219bfc	Bug#48483 crash in get_best_combination() The crash happens because greedy_serach can not determine best plan due to wrong inner table dependences. These dependences affects join table sorting which performs before greedy_search starting. In our case table which has real 'no dependences' should be put on top of the list but it does not happen as inner tables have no dependences as well. The fix is to exclude RAND_TABLE_BIT mask from condition which checks if table dependences should be updated. mysql-test/r/join.result: test result mysql-test/t/join.test: test case sql/sql_select.cc: RAND_TABLE_BIT mask should not be counted as it prevents update of inner table dependences. For example it might happen if RAND() function is used in JOIN ON clause.	16 years ago

Sergey Glukhov	f2aee2371e	Bug#45195 valgrind warnings about uninitialized values in store_record_in_cache() The problem becomes apparent only if HAVE_purify is undefined. It related to the part of code placed in open_table_from_share() fuction where we initialize record buffer only if HAVE_purify is enabled. So in case of HAVE_purify=OFF record buffer is not initialized on open table stage. Next we read key, find NULL value and update appropriate null bit but do not update record buffer. After that the record is stored in the join cache(store_record_in_cache). For CHAR fields we strip trailing spaces and in our case this procedure uses uninitialized record buffer. The fix is to skip stripping space procedure in case of null values for CHAR fields(partially based on 6.0 JOIN_CACHE implementation). mysql-test/r/join.result: test case mysql-test/t/join.test: test case sql/field.cc: code updated according to new CACHE_FIELD struct sql/sql_select.cc: code updated according to new CACHE_FIELD struct sql/sql_select.h: CACHE_FIELD struct: added new fields: Field field, uint type; removed fields: Field_blob blob_field, bool strip;	16 years ago
Sergey Petrunya	96e092dc73	Backport into MariaDB-5.2 the following: WL#2474 "Multi Range Read: Change the default MRR implementation to implement new MRR interface" WL#2475 "Batched range read functions for MyISAM/InnoDb" "Index condition pushdown for MyISAM/InnoDB" Igor's fix from sp1r-igor@olga.mysql.com-20080330055902-07614: There could be observed the following problems: 1. EXPLAIN did not mention pushdown conditions from on expressions in the 'extra' column. As a result if a query had no where conditions pushed down to a table, but had on conditions pushed to this table the 'extra' column in the EXPLAIN for the table missed 'using where'. 2. Conditions for ref access were not eliminated from on expressions though such conditions were eliminated from the where condition.	16 years ago
Georgi Kodinov	ac37324843	Bug #42116 : Mysql crash on specific query Queries with nested outer joins may lead to crashes or bad results because an internal data structure is not handled correctly. The optimizer uses bitmaps of nested JOINs to determine if certain table can be placed at a certain place in the JOIN order. It does maintain a bitmap describing in which JOINs last placed table is nested. When it puts a table it makes sure the bit of every JOIN that contains the table in question is set (because JOINs can be nested). It does that by recursively setting the bit for the next enclosing JOIN when this is the first table in the JOIN and recursively resetting the bit if it's the last table in the JOIN. When it removes a table from the join order it should do the opposite : recursively unset the bit if it's the only remaining table in this join and and recursively set the bit if it's removing the last table of a JOIN. There was an error in how the bits was set for the upper levels : when removing a table it was setting the bit for all the enclosing nested JOINs even if there were more tables left in the current JOIN (which practically means that the upper nested JOINs were not affected). Fixed by stopping the recursion at the relevant level. mysql-test/r/join.result: Bug #42116: test case mysql-test/t/join.test: Bug #42116: test case sql/sql_select.cc: Bug #41116: don't go up and set the bits if more tables in at the current JOIN level	16 years ago
Sergey Glukhov	5f8bb5c507	Bug#47150 Assertion in Field_long::val_int() on MERGE + TRIGGER + multi-table UPDATE The bug is not related to MERGE table or TRIGGER. More correct description would be 'assertion on multi-table UPDATE + NATURAL JOIN + MERGEABLE VIEW'. On PREPARE stage(see test case) we call mark_common_columns() func which creates ON condition for NATURAL JOIN and sets appropriate table read_set bitmaps for fields which are used in ON condition. On EXECUTE stage mark_common_columns() is not called, we set necessary read_set bitmaps in setup_conds(). But 'B.f1' field is already processed and related item alredy fixed before setup_conds() as updated field and setup_conds can not set read_set bitmap because of that. The fix is to set read_set bitmap for appropriate table field even if Item_direct_view_ref item which represents a refernce to this field is fixed. mysql-test/r/join.result: test result mysql-test/t/join.test: test case sql/item.cc: The bug is not related to MERGE table or TRIGGER.

unknown	353b6f26b1	Bug #27531 : the 4.1 fix. When checking for applicability of join cache we must disable its usage only if there is no temp table in use. When a temp table is used we can use join cache (and it will not make the result-set unordered) to fill the temp table. The filesort() operation is then applied to the data in the temp table and hence is not affected by join cache usage.

unknown	a7566db788	Bug #15355 : Common natural join column not resolved in prepared statement nested query Problem: There was a wrong context assigned to the columns that were added in insert_fields() when expanding a '*'. When this is done in a prepared statement it causes fix_fields() to fail to find the table that these columns reference. Actually the right context is set in setup_natural_join_row_types() called at the end of setup_tables(). However when executed in a context of a prepared statement setup_tables() resets the context, but setup_natural_join_row_types() was not setting it to the correct value assuming it has already done so. Solution: The top-most, left-most NATURAL/USING join must be set as a first_name_resolution_table in context even when operating on prepared statements. mysql-test/r/join.result: testsuite for the bug mysql-test/t/join.test: testsuite for the bug sql/sql_base.cc: The context must be set even when executed as prepared statement.	20 years ago

unknown	de1e87bbcd	Fix for BUG#15229. The cause of this bug was a design flaw due to which the list of natural join columns was incorrectly computed and stored for nested joins that are not natural joins, but are operands (possibly indirect) of nested joins. The patch corrects the flaw in a such a way, that the result columns of a table reference are materialized only if it is a leaf table (that is, only if it is a view, stored table, or natural/using join). mysql-test/r/join.result: Added test for BUG#15229 and uncommented failing test cases of BUG#15357 (now fixed by this patch). mysql-test/t/join.test: Added test for BUG#15229 and uncommented failing test cases of BUG#15357 (now fixed by this patch). sql/sql_base.cc: - Do not materialize the result columns of regular nested joins (that are not natural/using joins). - Moved most of the code that creates/adds new natural join column references to the method 'get_or_create_column_ref', and simplified 'mark_common_columns'. - Replaced a call to 'get_or_create_column_ref' with 'get_natural_column_ref' where it is for sure all columns are alredy created. sql/table.cc: - Modified the method 'get_or_create_column_ref' so that it adds itself the newly created natural join columns to the respective table reference. sql/table.h: - Modified the method 'get_or_create_column_ref' so that it adds itself the newly created natural join columns to the respective table reference.	20 years ago

There is one find_field_in_XXX procedure per each type of table reference (stored table, merge view, or natural join); one meta-procedure that selects the correct one depeneding on the table reference; and one procedure that goes over a list of table referenes. - NATURAL/USING joins are processed through the procedures: mark_common_columns, store_natural_using_join_columns, store_top_level_join_columns, setup_natural_join_row_types. The entry point to processing NATURAL/USING joins is the procedure 'setup_natural_join_row_types'. - Replaced the specialized Field_iterator_XXX iterators with one generic iterator over the fields of a table reference. - Simplified 'insert_fields' and 'setup_conds' due to encapsulation of the processing of natural joins in a separate set of procedures. sql/sql_class.h: - Commented old code. sql/sql_delete.cc: - Pass the FROM clause to setup_tables. sql/sql_help.cc: - pass the end name resolution table to find_field_in_tables - adjust the list of tables for name resolution sql/sql_insert.cc: - Changed the code that saves and restores the current context to support the list of tables for name resolution - context->first_name_resolution_table, and table_list->next_name_resolution_table. Needed to support an ugly trick to resolve inserted columns only in the first table. - Added Name_resolution_context::[first \| last]_name_resolution_table. - Commented old code sql/sql_lex.cc: - set select_lex.parent_lex correctly - set correct state of the current name resolution context sql/sql_lex.h: - Added a stack of name resolution contexts to support local contexts for JOIN ... ON conditions. - Commented old code. sql/sql_load.cc: - Pass the FROM clause to setup_tables. sql/sql_olap.cc: - Pass the FROM clause to setup_tables. sql/sql_parse.cc: - correctly set SELECT_LEX::parent_lex - set the first table of the current name resoltion context - added support for NATURAL/USING joins - commented old code sql/sql_select.cc: - Pass the FROM clause to setup_tables. - Pass the end table to find_field_in_tables - Improved comments sql/sql_show.cc: - Set SELECT_LEX::parent_lex. sql/sql_update.cc: - Pass the FROM clause to setup_tables. sql/sql_yacc.yy: - Added support for a stack of name resolution contexts needed to implement name resolution for JOIN ... ON. A context is pushed for each new JOIN ... ON, and popped afterwards. - Added support for NATURAL/USING joins. sql/table.cc: - Added new class Natural_join_column to hide the heterogeneous representation of column references for stored tables and for views. - Added a new list TABLE_LIST::next_name_resolution_table to support name resolution with NATURAL/USING joins. Also added other members to TABLE_LIST to support NATURAL/USING joins. - Added a generic iterator over the fields of table references of various types - class Field_iterator_table_ref sql/table.h: - Added new class Natural_join_column to hide the heterogeneous representation of column references for stored tables and for views. - Added a new list TABLE_LIST::next_name_resolution_table to support name resolution with NATURAL/USING joins. Also added other members to TABLE_LIST to support NATURAL/USING joins. - Added a generic iterator over the fields of table references of various types - class Field_iterator_table_ref tests/mysql_client_test.c: Adjusted according to standard NATURAL JOIN syntax.	20 years ago
unknown	f0ac45bcf7	join_nested.test, join_nested.result: Added a case for bug #4976 when one of the inner tables is empty. select.result, join.result: Reversed the previous change of the erronious fix for bug #4976. sql_select.cc: The previous fix for bug 4976 was reversed as it erroniously converted an outer join into an innner join when on_expression does not refer to outer tables. This is not valid if inner tables return an empty set. Setting dependency on outer tables was added for the above cases. To fix the crash in the test case of bug #4976 a guard was added that blocks running the crashing code for nested outer joins. sql/sql_select.cc: The previous fix for bug 4976 was reversed as it erroniously converted an outer join into an innner join when on_expression does not refer to outer tables.
