Fixed bug #8528.
Representation for single-table views was made similar to
representation for multi-table views.
view.test:
Added test case for bug #8528.
view.result:
Added test case for bug #8528. Fixed other test cases.
with cursor". The patch refactors do_select/sub_select
functions, which implement the nested loop algorithm, and reuses them to
fetch rows for cursors as well.
Pushing with view.test failing (--ps-protocol).
Make get_quick_select_for_ref() accept estimated # records as parameter and
set QUICK_RANGE_SELECT::records, as this value is used to allocate buffers
in Multi-Range Read.
to read and write
Changed Server code, added new interface to handler and changed the
NDB handler, InnoDB handler and Federated handler that previously used
query_id
Bug#10202 fix (one-liner fix for memory leak)
Fixed bug #9681.
The bug happened with queries using derived tables specified by
a SELECT with ROLLUP, such as:
SELECT * FROM (SELECT a, SUM(a) FROM t1 GROUP BY a WITH ROLLUP) t2,
if column a of table t1 is declared as NOT NULL.
This was to the fact that the first column of the temporary table
created to contain the derived table erroneously inherited the NOT NULL
attribute from column a.
olap.result, olap.test:
Added a test case for bug #9681.
Don't produce data truncation warnings from within cp_buffer_from_ref(). This function
is only used to make index search tuples and data truncation that occurs here has no
relation with truncated values being saved into tables.
Added a test case for bug #9338.
sql_select.cc:
Fixed bug #9338.
When an occurence of a field reference has to be replaced
by another field reference the whole Item_field must be
replaced.
item.cc:
Fixed bug #9338.
The method Item_field::replace_equal_field_processor was
replaced by Item_field::replace_equal_field. The new method
is used to replace the occurences of Item_field objects.
item.h:
Fixed bug #9338.
The virtual function replace_equal_field_processor was replaced
by replace_equal_field. The latter is supposed to be used as a
callback function in calls of the method transform.
Fixed warnings by valgrind for sum_distinct.test
Enable buffered-record-reads after filesort for InnoDB tables with short primary key
Enabled sort-with-data for MyISAM temporary files
