MDEV-6099 Bad results for DATE_ADD(.., INTERVAL 2000000000000000000.0 SECOND)
MDEV-6097 Inconsistent results for CAST(int,decimal,double AS DATETIME)
MDEV-6100 No warning on CAST(9000000 AS TIME)
on server shutdown after SELECT with CONVERT_TZ
It's wrong to return my_empty_string from val_str().
Removing my_empty_string. Using make_empty_result() instead.
Other fix of maybe_null problem and revert of revno: 3608 "MDEV-3873 & MDEV-3876 & MDEV-3912 : Wrong result (extra rows) with ALL subquery from a MERGE view."
Cleanup: remove TIME_FUZZY_DATE.
Introduce TIME_FUZZY_DATES which means "very fuzzy, the resulting
value is only used for comparison. It can be invalid date, fine, as long as it can be
compared".
Updated many tests results (they're better now).
Item_func_make_set wasn't taking into account the first argument when
calculating maybe_null.
sql/item_strfunc.cc:
rewrite Item_func_make_set, removing separate storage of the first argument
sql/item_strfunc.h:
rewrite Item_func_make_set, removing separate storage of the first argument
from a MERGE view.
The problem was in the lost ability to be null for the table of a left join if it
is a view/derived table.
It hapenned because setup_table_map(), was called earlier then we merged
the view or derived.
Fixed by propagating new maybe_null flag during Item::update_used_tables().
Change in join_outer.test and join_outer_jcl6.test appeared because
IS NULL reported no used tables (i.e. constant) for argument which could not be
NULL and new maybe_null flag was propagated for IS NULL argument (Item_field)
because table the Item_field belonged to changed its maybe_null status.

Problem description:
When a view is created using function FORMAT and if FORMAT function uses locale
option,definition of view saved into server doesn't contain that locale information,
Ex:
create table test2 (bb decimal (10,2));
insert into test2 values (10.32),(10009.2),(12345678.21);
create view test3 as select format(bb,1,'sk_SK') as cc from test2;
select * from test3;
+--------------+
| cc |
+--------------+
| 10.3 |
| 10,009.2 |
| 12,345,678.2 |
+--------------+
3 rows in set (0.02 sec)
show create view test3
View: test3
Create View: CREATE ALGORITHM=UNDEFINED DEFINER=`root`@`localhost`
SQL SECURITY DEFINER VIEW `test3` AS select format(`test2`.`bb`,1) AS `cc`
from `test2`
character_set_client: latin1
collation_connection: latin1_swedish_ci
1 row in set (0.02 sec)
Problem Analysis:
The function Item_func_format::print() which prints the query string to create
the view does not print the third argument (i.e the locale information). Hence
view is created without locale information.
Problem Solution:
If argument count is more than 2 we now print the third argument onto the query string.
Files changed:
sql/item_strfunc.cc
Function call changes: Item_func_format::print()
