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. Now all outer fields are substituted with references to them (Item_outer_ref objects) in the Item_field::fix_outer_field() function. The original field is saved in the Item_outer_ref object. sql/item.h: Bug#23800: Correlated sub query returning incorrect results when operated upon. Added the Item_outer_ref class. sql/mysql_priv.h: Bug#23800: Correlated sub query returning incorrect results when operated upon.

unknown	a97fd19371	Bug #25831 : Deficiencies in INSERT ... SELECT ... field name resolving. Several problems fixed: 1. There was a "catch-all" context initialization in setup_tables() that was causing the table that we insert into to be visible in the SELECT part of an INSERT .. SELECT .. statement with no tables in its FROM clause. This was making sure all the under-initialized contexts in various parts of the code are not left uninitialized. Fixed by removing the "catch-all" statement and initializing the context in the parser. 2. Incomplete name resolution context when resolving the right-hand values in the ON DUPLICATE KEY UPDATE ... part of an INSERT ... SELECT ... caused columns from NATURAL JOIN/JOIN USING table references in the FROM clause of the select to be unavailable. Fixed by establishing a proper name resolution context. 3. When setting up the special name resolution context for problem 2 there was no check for cases where an aggregate function without a GROUP BY effectively takes the column from the SELECT part of an INSERT ... SELECT unavailable for ON DUPLICATE KEY UPDATE. Fixed by checking for that condition when setting up the name resolution context. mysql-test/r/insert_update.result: Bug #25831: Deficiencies in INSERT ...

unknown	d5813a06f6	Bug#16630: The update fields of the INSERT .. SELECT .. ON DUPLICATE KEY UPDATE contains wrong data if the SELECT employs a temporary table. If the UPDATE values of the INSERT .. SELECT .. ON DUPLICATE KEY UPDATE statement contains fields from the SELECT part and the select employs a temporary table then those fields will contain wrong values because they aren't corrected to get data from the temporary table. The solution is to add these fields to the selects all_fields list, to store pointers to those fields in the selects ref_pointer_array and to access them via Item_ref objects. The substitution for Item_ref objects is done in the new function called Item_field::update_value_transformer(). It is called through the item->transform() mechanism at the end of the select_insert::prepare() function. sql/item.cc: Bug#16630: The update fields of the INSERT .. SELECT ..

unknown	4dc7c1aa46	Bug#24660: "enum" field type definition problem ENUMs weren't allowed to have character 0xff, a perfectly good character in some locales. This was circumvented by mapping 0xff in ENUMs to ',', thereby prevent actual commas from being used. Now if 0xff makes an appearance, we find a character not used in the enum and use that as a separator. If no such character exists, we throw an error. Any solution would have broken some sort of existing behaviour. This solution should serve both fractions (those with 0xff and those with ',' in their enums), but WILL REQUIRE A DUMP/RESTORE CYCLE FROM THOSE WITH 0xff IN THEIR ENUMS. :-/ That is, mysqldump with their current server, and restore when upgrading to one with this patch. mysql-test/r/type_enum.result: Bug#24660: "enum" field type definition problem Show that enums can now contain NAMES_SEP_CHAR (0xff, which is a perfectly respectable char in some locales), or ',', or both. mysql-test/t/type_enum.test: Bug#24660: "enum" field type definition problem Show that enums can now contain NAMES_SEP_CHAR (0xff, which is a perfectly respectable char in some locales), or ',', or both. sql/table.cc: Bug#24660: "enum" field type definition problem Revert fix for Bug#20922. sql/unireg.cc: Bug#24660: "enum" field type definition problem Use a field-separator for ENUM-values that is not part of those values.
