unknown	c71a6428d8	BUG#33794 "MySQL crashes executing specific query": The problem occurred when one had a subquery that had an equality X=Y where Y referred to a named select list expression from the parent select. MySQL crashed when trying to use the X=Y equality for ref-based access. Fixed by allowing non-Item_field items in the described case. mysql-test/r/subselect.result: BUG#33794 "MySQL crashes executing specific query" - Testcase mysql-test/t/subselect.test: BUG#33794 "MySQL crashes executing specific query" - Testcase sql/sql_select.cc: BUG#33794 "MySQL crashes executing specific query" get_store_key() assumed that if it got a reference t.key=Item_outer_ref(Item_direct_ref(x)) then x was an Item_field object, which is not the case when one refers to a named select list expression out ot subquery.	18 years ago
unknown	8845553a81	Bug#33675: Usage of an uninitialized memory by filesort in a subquery caused server crash. The filesort implementation has an optimization for subquery execution which consists of reusing previously allocated buffers. In particular the call to the read_buffpek_from_file function might be skipped when a big enough buffer for buffer descriptors (buffpeks) is already allocated. Beside allocating memory for buffpeks this function fills allocated buffer with data read from disk. Skipping it might led to using an arbitrary memory as fields' data and finally to a crash. Now the read_buffpek_from_file function is always called. It allocates new buffer only when necessary, but always fill it with correct data. sql/filesort.cc: Bug#33675: Usage of an uninitialized memory by filesort in a subquery caused server crash.Now the read_buffpek_from_file function is always called.

unknown	f3f9855d13	Bug #32036 : EXISTS within a WHERE clause with a UNION crashes MySQL 5.122 There was a difference in how UNIONs are handled on top level and when in sub-query. Because the rules for sub-queries were syntactically allowing cases that are not currently supported by the server we had crashes (this bug) or wrong results (bug 32051). Fixed by making the syntax rules for UNIONs match the ones at top level. These rules however do not support nesting UNIONs, e.g. (SELECT a FROM t1 UNION ALL SELECT b FROM t2) UNION (SELECT c FROM t3 UNION ALL SELECT d FROM t4) Supports for statements with nested UNIONs will be added in a future version. mysql-test/r/subselect.result: Bug #32036: test case mysql-test/t/subselect.test: Bug #32036: test case sql/sql_yacc.yy: Bug #32036: Make the syntax rules for UNIONs in subqueries the same as for top level UNIONs.	18 years ago

unknown	e9832ceeac	Bug #30788 : Inconsistent retrieval of char/varchar Index lookup does not always guarantee that we can simply remove the relevant conditions from the WHERE clause. Reasons can be e.g. conversion errors, partial indexes etc. The optimizer was removing these parts of the WHERE condition without any further checking.

unknown	13105534fa	Bug#31048: Many nested subqueries may cause server crash. This bug is actually two. The first one manifests itself on an EXPLAIN SELECT query with nested subqueries that employs the filesort algorithm. The whole SELECT under explain is marked as UNCACHEABLE_EXPLAIN to preserve some temporary structures for explain. As a side-effect of this values of nested subqueries weren't cached and subqueries were re-evaluated many times. Each time buffer for filesort was allocated but wasn't freed because freeing occurs at the end of topmost SELECT. Thus all available memory was eaten up step by step and OOM event occur. The second bug manifests itself on SELECT queries with conditions where a subquery result is compared with a key field and the subquery itself also has such condition. When a long chain of such nested subqueries is present the stack overrun occur. This happens because at some point the range optimizer temporary puts the PARAM structure on the stack. Its size if about 8K and the stack is exhausted very fast. Now the subselect_single_select_engine::exec function allows subquery result caching when the UNCACHEABLE_EXPLAIN flag is set. Now the SQL_SELECT::test_quick_select function calls the check_stack_overrun function for stack checking purposes to prevent server crash. mysql-test/t/subselect.test: Added a test case for the bug#31048: Many nested subqueries may cause server crash. mysql-test/r/subselect.result: Added a test case for the bug#31048: Many nested subqueries may cause server crash. sql/opt_range.cc: Bug#31048: Many nested subqueries may cause server crash.

unknown	c2e961cf2e	Bug#27333: subquery grouped for aggregate of outer query / no aggregate of subquery The optimizer counts the aggregate functions that appear as top level expressions (in all_fields) in the current subquery. Later it makes a list of these that it uses to actually execute the aggregates in end_send_group(). That count is used in several places as a flag whether there are aggregates functions. While collecting the above info it must not consider aggregates that are not aggregated in the current context. It must treat them as normal expressions instead. Not doing that leads to incorrect data about the query, e.g. running a query that actually has no aggregate functions as if it has some (and hence is expected to return only one row). Fixed by ignoring the aggregates that are not aggregated in the current context. One other smaller omission discovered and fixed in the process : the place of aggregation was not calculated for user defined functions. Fixed by calling Item_sum::init_sum_func_check() and Item_sum::check_sum_func() as it's done for the rest of the aggregate functions. mysql-test/r/subselect.result: Bug #27333: test case mysql-test/t/subselect.test: Bug #27333: test case sql/item_subselect.cc: Bug#27333: need select_lex to filter out aggregates that are not aggregated in the current select. sql/item_sum.cc: Bug#27333: need select_lex to filter out aggregates that are not aggregated in the current select. sql/item_sum.h: Bug#27333: calculate the place of aggregation for user defined functions. sql/sql_select.cc: Bug#27333: When counting the aggregated functions and collecting a list of them we must not consider the aggregates that are not aggregated in the local context as "local" : i.e. we must treat them as normal functions and not add them to the aggregate functions list. sql/sql_select.h: Bug#27333: need select_lex to filter out aggregates that are not aggregated in the current select.	19 years ago
unknown	d8e2f2622d	Fixed bug #28811 : crash for a query containing a subquery with ORDER BY and LIMIT 1. The bug was introduced by the patch for bug 21727. The patch erroneously skipped initialization of the array of headers for sorted records for non-first evaluations of the subquery. To fix the problem a new parameter has been added to the function make_char_array that performs the initialization. Now this function is called for any invocation of the filesort procedure. Yet it allocates the buffer for sorted records only if this parameter is NULL. mysql-test/r/subselect.result: Added a test case for bug #28811. mysql-test/t/subselect.test: Added a test case for bug #28811.	19 years ago

unknown	8c4ff24b56	Fixed bug #28728 : a crash when executing EXPLAIN EXTENDED for a query using a derived table over a grouping subselect. This crash happens only when materialization of the derived tables requires creation of auxiliary temporary table, for example when a grouping operation is carried out with usage of a temporary table. The crash happened because EXPLAIN EXTENDED when printing the query expression made an attempt to use the objects created in the mem_root of the temporary table which has been already freed by the moment when printing is called. This bug appeared after the method Item_field::print() had been introduced. mysql-test/r/subselect.result: Added a test case for bug #28728. mysql-test/t/subselect.test: Added a test case for bug #28728. sql/sql_select.cc: Fixed bug #28728: a crash when executing EXPLAIN EXTENDED for a query using a derived table over a grouping subselect.

unknown	0ad4e1b2a6	Bug #27807 . Non-correlated scalar subqueries may get executed in EXPLAIN at the optimization phase if they are part of a right hand sargable expression. If the scalar subquery uses a temp table to materialize its results it will replace the subquery structure from the parser with a simple select from the materialization table. As a result the EXPLAIN will crash as the temporary materialization table is not to be shown in EXPLAIN at all.

unknown	1cf3b96513	Bug#27321: Wrong subquery result in a grouping select. The Item_outer_ref class based on the Item_direct_ref class was always used to represent an outer field. But if the outer select is a grouping one and the outer field isn't under an aggregate function which is aggregated in that outer select an Item_ref object should be used to represent such a field. If the outer select in which the outer field is resolved isn't grouping then the Item_field class should be used to represent such a field. This logic also should be used for an outer field resolved through its alias name. Now the Item_field::fix_outer_field() uses Item_outer_field objects to represent aliased and non-aliased outer fields for grouping outer selects only. Now the fix_inner_refs() function chooses which class to use to access outer field - the Item_ref or the Item_direct_ref. An object of the chosen class substitutes the original field in the Item_outer_ref object. The direct_ref and the found_in_select_list fields were added to the Item_outer_ref class. mysql-test/t/subselect3.test: Some test cases were corrected after the fix for the bug#27321. mysql-test/r/subselect3.result: Some test cases were corrected after the fix for the bug#27321. mysql-test/t/subselect.test: Added a test case for the bug#27321: Wrong subquery result in a grouping select. mysql-test/r/subselect.result: Added a test case for the bug#27321: Wrong subquery result in a grouping select.

unknown	f8855142d7	Bug#23800: Outer fields in correlated subqueries is used in a temporary table created for sorting. Any outer reference in a subquery was represented by an Item_field object. If the outer select employs a temporary table all such fields should be replaced with fields from that temporary table in order to point to the actual data. This replacement wasn't done and that resulted in a wrong subquery evaluation and a wrong result of the whole query. Now any outer field is represented by two objects - Item_field placed in the outer select and Item_outer_ref in the subquery. Item_field object is processed as a normal field and the reference to it is saved in the ref_pointer_array. Thus the Item_outer_ref is always references the correct field. The original field is substituted for a reference in the Item_field::fix_outer_field() function. New function called fix_inner_refs() is added to fix fields referenced from inner selects and to fix references (Item_ref objects) to these fields. The new Item_outer_ref class is a descendant of the Item_direct_ref class. It additionally stores a reference to the original field and designed to behave more like a field. sql/item.cc: Bug#23800: Correlated sub query returning incorrect results when operated upon.

unknown	a1e20e04d8	Bug#21904 (parser problem when using IN with a double "(())") Before this fix, a IN predicate of the form: "IN (( subselect ))", with two parenthesis, would be evaluated as a single row subselect: if the subselect returns more that 1 row, the statement would fail. The SQL:2003 standard defines a special exception in the specification, and mandates that this particular form of IN predicate shall be equivalent to "IN ( subselect )", which involves a table subquery and works with more than 1 row. This fix implements "IN (( subselect ))", "IN ((( subselect )))" etc as per the SQL:2003 requirement. All the details related to the implementation of this change have been commented in the code, and the relevant sections of the SQL:2003 spec are given for reference, so they are not repeated here. Having access to the spec is a requirement to review in depth this patch. mysql-test/r/subselect.result: Implement IN predicate special exceptions with subselects. mysql-test/t/subselect.test: Implement IN predicate special exceptions with subselects. sql/item_subselect.cc: Implement IN predicate special exceptions with subselects. sql/item_subselect.h: Implement IN predicate special exceptions with subselects. sql/sql_yacc.yy: Implement IN predicate special exceptions with subselects, cleanup.	19 years ago
unknown	da561a802c	Fixed bug #24653 . The bug report has demonstrated the following two problems. 1. If an ORDER/GROUP BY list includes a constant expression being optimized away and, at the same time, containing single-row subselects that return more that one row, no error is reported. Strictly speaking the standard allows to ignore error in this case. Yet, now a corresponding fatal error is reported in this case. 2. If a query requires sorting by expressions containing single-row subselects that, however, return more than one row, then the execution of the query may cause a server crash. To fix this some code has been added that blocks execution of a subselect item in case of a fatal error in the method Item_subselect::exec. mysql-test/r/subselect.result: Added a test cases for bug #24653. mysql-test/t/subselect.test: Added a test cases for bug #24653. sql/filesort.cc: Fixed bug #24653.

Removed an assertion that caused an abort for subqueries without tables and no WHERE condition. Blocked substitution of a single-row subquery without tables for the constant row from its select list when the subquery contained a WHERE condition. This optimization is valid only for subquries without tables with no conditions. Any subquery without tables with WHERE clause returns NULL if the WHERE condition is FALSE. Erroneously it was always considered as non-nullable that could trigger another optimization concerning IS NULL predicates which is applicable only for non-nullable expressions and ultimately led to a wrong result returned by the outer query. Added a proper implementation of the virtual method may_be_null for class subselect_single_select_engine. sql/item_subselect.h: Fixed bug #24670: optimizations that are legal only for subqueries without tables and no WHERE condition were applied for any subquery without tables.

unknown	e8b32b2b01	bug #20835 (Subqueries: literal string with =any fails) We create Item_cache_* object for each operand for each left operand of a subquery predicate. We also create Item_func_conv_charset for each string constant that needs charset conversion. So here we have Item_cache wrapped into Item_func_conv_charset. When Item_func_conv_charset wraps an constant Item it gets it's value in constructor. The problem is that Item_cache is ready to be used only at execution time, which is too late.

The cause for the bug is that during subquery reinitialization/re-execution, the optimizer reallocates JOIN::join_tab, JOIN::table in make_simple_join() and the local variable in 'sortorder' in create_sort_index(), which is allocated by make_unireg_sortorder(). Care must be taken not to allocate anything into the thread's memory pool while re-initializing query plan structures between subquery re-executions. All such items mush be cached and reused because the thread's memory pool is freed at the end of the whole query. Note that they must be cached and reused even for queries that are not otherwise cacheable because otherwise it will grow the thread's memory pool every time a cacheable query is re-executed.

unknown	c9bba13aee	Bug#14654 : Cannot select from the same table twice within a UNION statement Made the parser to support parenthesis around UNION branches. This is done by amending the rules of the parser so it generates the correct structure. Currently it supports arbitrary subquery/join/parenthesis operations in the EXISTS clause. In the IN/scalar subquery case it will allow adding nested parenthesis only if there is an UNION clause after the parenthesis. Otherwise it will just treat the multiple nested parenthesis as a scalar expression. It adds extra lex level for ((SELECT ...) UNION ...) to accommodate for the UNION clause. mysql-test/r/subselect.result: Bug#14654 : Cannot select from the same table twice within a UNION statement - test cases mysql-test/t/subselect.test: Bug#14654 : Cannot select from the same table twice within a UNION statement - test cases sql/sql_yacc.yy: Bug#14654 : Cannot select from the same table twice within a UNION statement - shuffle around the rules for the parenthesis in subselect	19 years ago
