unknown	4b36c1d8ff	Bug #16458 : Simple SELECT FOR UPDATE causes "Result Set not updatable" error 'SELECT DISTINCT a,b FROM t1' should not use temp table if there is unique index (or primary key) on a. There are a number of other similar cases that can be calculated without the use of a temp table : multi-part unique indexes, primary keys or using GROUP BY instead of DISTINCT. When a GROUP BY/DISTINCT clause contains all key parts of a unique index, then it is guaranteed that the fields of the clause will be unique, therefore we can optimize away GROUP BY/DISTINCT altogether. This optimization has two effects: * there is no need to create a temporary table to compute the GROUP/DISTINCT operation (or the temporary table will be smaller if only GROUP is removed and DISTINCT stays or if DISTINCT is removed and GROUP BY stays) * this causes the statement in effect to become updatable in Connector/Java because the result set columns will be direct reference to the primary key of the table (instead to the temporary table that it currently references). Implemented a check that will optimize away GROUP BY/DISTINCT for queries like the above. Currently it will work only for single non-constant table in the FROM clause. mysql-test/r/distinct.result: Bug #16458: Simple SELECT FOR UPDATE causes "Result Set not updatable" error - test case mysql-test/t/distinct.test: Bug #16458: Simple SELECT FOR UPDATE causes "Result Set not updatable" error - test case sql/sql_select.cc: Bug #16458: Simple SELECT FOR UPDATE causes "Result Set not updatable" error - disable GROUP BY if contains the fields of a unique index.	20 years ago

unknown	16ce188ded	Bug#11824 - internal /tmp/.{MYD,MYI} files remain, causing subsequent queries to fail Very complex select statements can create temporary tables that are too big to be represented as a MyISAM table. This was not checked at table creation time, but only at open time. The result was an attempt to delete the "impossible" table. But if the server is built --with-raid, MyISAM tries to open the table before deleting the files. It needs to find out if the table uses the raid support and how many raid chunks there are. This is done with an open "for repair", which will almost always succeed. But in this case we have an "impossible" table. The open failed. Hence the files were not deleted. Also the error message was a bit unspecific. I turned an open error in this situation into the assumption of having no raid support on the table. Thus the normal data file is tried to be deleted. This may however leave existing raid chunks behind. I also added a check in mi_create() to prevent the creation of an "impossible" table. A more decriptive error message is given in this case. No test case. The required select statement is way too large for the test suite. I added a test script to the bug report. myisam/mi_create.c: Bug#11824 - internal /tmp/.{MYD,MYI} files remain, causing subsequent queries to fail Added a check to mi_create() that the table description header of the index file does not exceed 64KB. The header has only 16 bits to encode its length. myisam/mi_delete_table.c: Bug#11824 - internal /tmp/*.{MYD,MYI} files remain, causing subsequent queries to fail Interpret error in table open as not having a raid configuration on the tbale. Thus try to delete the normal data file, but leave behind raid chunks if they exist.	20 years ago

unknown	d62551af39	Added a test case for bug #18359 . This was another manifestation of the problems fixed in the patch for bug 16674.

unknown	e8adb49910	Fixed bug #20076 . Server crashed in some cases when a query required a MIN/MAX agrregation for a 'ucs2' field. In these cases the aggregation caused calls of the function update_tmptable_sum_func that indirectly invoked the method Item_sum_hybrid::min_max_update_str_field() containing a call to strip_sp for a ucs2 character set. The latter led directly to the crash as it used my_isspace undefined for the ucs2 character set. Actually the call of strip_sp is not needed at all in this situation and has been removed by the fix. mysql-test/r/ctype_ucs.result: Added a test case for bug #20076. mysql-test/t/ctype_ucs.test: Added a test case for bug #20076.	20 years ago

Given field a is declared as a varchar(16) collate utf8_unicode_ci INDEX(a(4)) gives us an example of such an index. Wrong key comparisons could lead to wrong result sets if the selected query execution plan used a range scan by a partial index over a utf8 character field.
