kaa@polly.local	268c7a3522	Bug #20924 : CAST(expr as UNSIGNED) returns SIGNED value when used in various functions - Honor unsigned_flag in the corresponding functions - Use compare_int_signed_unsigned()/compare_int_unsigned_signed() instead of explicit comparison in GREATEST() and LEAST()	19 years ago
bar@mysql.com	a481a35237	Bug#8663 cant use bgint unsigned as input to cast Problem: cast to unsigned limited result to max signed bigint 9223372036854775808, instead of max unsigned bigint 18446744073709551615. Fix: don't use args[0]->val_int() when casting from a floating point number, use val() instead, with range checkings, special to unsigned data type. item_func.cc: Special handling of cast from REAL_RESULT to unsigned int: we cannot execute args[0]->val_int() because it cuts max allowed value to LONGLONG_INT, instead of ULONGLONG_INT required. count_distinct3.test: Getting rid of "Data truncated; out of range ..." warnings. cast.test, cast.result: Adding test case. ps.result: Fixing that cast from 6570515219.6535 to unsigned didn't round to 6570515220, and returned 6570515219 instead.	20 years ago

aelkin@mysql.com	8c57924a6a	Bug#19136: Crashing log-bin and uninitialized user variables in a derived table The reason of the bug is in that `get_var_with_binlog' performs missed assingment of the variables as side-effect. Doing that it eventually calls `free_underlaid_joins' to pass as an argument `thd->lex->select_lex' of the lex which belongs to the user query, not to one which is emulated i.e SET @var1:=NULL. `get_var_with_binlog' is refined to supply a temporary lex to sql_set_variables's stack.	20 years ago
kroki@mysql.com	c77336c260	Bug#16501: IS_USED_LOCK does not appear to work Update User_level_lock::thread_id on acquiring an existing lock, and reset it on lock release.	20 years ago
evgen@moonbone.local	ac54aa2aee	Fixed bug#14169: type of group_concat() result changed to blob if tmp_table was used In a simple queries a result of the GROUP_CONCAT() function was always of varchar type. But if length of GROUP_CONCAT() result is greater than 512 chars and temporary table is used during select then the result is converted to blob, due to policy to not to store fields longer than 512 chars in tmp table as varchar fields. In order to provide consistent behaviour, result of GROUP_CONCAT() now will always be converted to blob if it is longer than 512 chars. Item_func_group_concat::field_type() is modified accordingly.	20 years ago
sasha@asksasha.com	41752fa9a0	fix for BUG#7947 - failure to log DO RELEASE_LOCK() if we disconnect in the middle of transaction while holding the lock. Also test to make sure other binlogging issues reported in the bug have been addressed.	20 years ago

bar@mysql.com	0c2035b7bd	func_gconcat.result, func_gconcat.test: Adding test item_sum.cc: Adding a call for collation/charset aggregation, to collect attributes from the arguments. The actual bug fix. item_func.h, item_func.cc, item.h, item.cc: - Removing collation aggrgation functions from Item_func class in item.cc, and adding it as non-class functions in item.cc to be able to reuse this code for group_concat. - Adding replacement for these functions into Item_func class as wrappers for moved functions, to minizize patch size,	21 years ago

monty@mysql.com	29fd1f2fd9	Move USE_PRAGMA_IMPLEMENTATION to proper place Ensure that 'null_value' is not accessed before val() is called in FIELD() functions Fixed initialization of key maps. This fixes some problems with keys when you have more than 64 keys Fixed that ROLLUP don't always create a temporary table. This fix ensures that func_gconcat.test results are now predictable	21 years ago

konstantin@mysql.com	3589e78fda	A fix and test case for Bug#9096 "select doesn't return all matched records if prepared statements is used". This fix changes equality evaluation method of basic constants from by-name to by-value, thus effectively enabling use of parameter markers in some optimizations (constants propagation, evaluation of possible keys for query).	21 years ago
dlenev@brandersnatch.localdomain	8ee6d33bdd	Fix for Bug #9913 "udf_deinit is not called after execution of PS" (aka "deinit is not called when calling udf from trigger"). We should call udf_deinit() function during cleanup phase after prepared (or ordinary) statement execution instead of calling it from Item's desctructor. No test case is provided since it is hard to test UDF's from our test suite.	21 years ago
monty@mysql.com	fbf31c4a8c	CAST(string_argument AS UNSIGNED) didn't work for big integers above the signed range. (Bug #7036 ) Produce warnings of wrong cast of strings to signed/unsigned.

bar@mysql.com	a7b877df78	Bugs#9129: CHARSET(), COLLATION(), COERCIBILITY() not always correct for NULL values. Now they always result a non NULL value even the argument is NULL. It is more usefull for debugging purposes.	21 years ago
bar@mysql.com	7e8e033290	type_blob.result, func_system.result, func_str.result, ctype_collate.result: fixing test results accordingly. func_system.test: New test that illegal mix of collations does not happen anymore. item_strfunc.h: safe_charset_converter() was added for system constants. item_strfunc.cc: safe_charset_converter() was added for system constants. item_func.cc, item.h, item.cc: Bug#8291: Illegal collation mix with USER() function. After discussion with PeterG and Serge, a new coercibility level for "system constants" was introduced, between COERRIBLE and IMPLICIT. Thus: SELECT col1 = USER() FROM t1; - is done according to col1 collation. SELECT 'string' = USER(); - is done according to USER() collation. At the same time, "nagg" and "strong" members were removed as unused. item_create.cc: Version is a system constant too.	21 years ago
bar@mysql.com	89a5530822	A user variable are now always have IMPLICIT coercibility, independently from the expression it is initialized from. In other words, this change treats a user variable like a table with one column and one record. Discussed with PeterG, Serg and Lars. This change also simplifies replication allowing not to replicate variables' coercibility.	21 years ago
monty@mysql.com	79ec81071a	Better bugfix for "HAVING when refering to RAND()" (Bug #8216 ) Ensure that references in HAVING, ORDER BY or GROUP BY are calculated after fields in SELECT. This will ensure that any reference to these has a valid value. Generalized the code for split_sum_func()	21 years ago

ram@gw.mysql.r18.ru	da562b7e02	A fix (bug #7281 : RAND(RAND) crashes server).	21 years ago
sergefp@mysql.com	da332aca40	Fix for BUG#6825: When calculating Item_func_neg::max_length, add 1 for '-'. For numeric constants we only need to add, since the parser doesn't produce negative numbers. For strings we only add (we actually could substract 1 if given string is a constant and it has '-number' form but we're not doing that because * we set max_length bigger then necessary in other cases as well. * the current solution is simpler and safer (bigger max_length is better then cutting out)	21 years ago
sergefp@mysql.com	3c8f48d2e3	* Added comments and one assert * Backport of safety measures from 5.0: make numeorous replaces: s/item->fix_fields()/if (!item->fixed) item->fix_fields()	21 years ago
sergefp@mysql.com	3ceb04a5d8	Merge of fix for BUG#6976 continued: pulling in some Item_ref changes from 5.0 * Added Item_ref::set_properties * Item_ref::Item_ref now expects to get in *item either NULL - then fix_fields() will be called later or ptr to Item it will refer to - then an equivalent of fix_fields() call is performed	21 years ago
sergefp@mysql.com	9ed8cd701b	Merging fix for BUG#6976 from 4.0 to 4.1 The problem in 4.1 was the same as in 4.0 - fix_fields() not called for created Item_ref. The fix is similar too - initialize Item_refs in ctor (but don't interfere with cases when Item_ref is used by subselects).	21 years ago
