de06a2f8b7 [minor](test) remove useless date case (#25941) 
remove case
```sql
select datediff('10000-10-31', '2010-10-15')
```

because Nereids throw exception when cast '10000-10-31' to date,
but legacy planner return null on it

c9f5142420 [Imporve](UNIX_TIMESTAMP) UNIX_TIMESTAMP func support 'yyyy-MM-dd HH:mm:ss' format (#24561) 
UNIX_TIMESTAMP function data format parameter supports 'yyyy-MM-dd HH:mm:ss'
The implementation is the same as the date_format function
before:
```sql
mysql> select UNIX_TIMESTAMP('2023-09-18 00:00:00','yyyy-MM-dd HH:mm:ss');
+--------------------------------------------------------------+
| unix_timestamp('2023-09-18 00:00:00', 'yyyy-MM-dd HH:mm:ss') |
+--------------------------------------------------------------+
|                                                         NULL |
+--------------------------------------------------------------+
1 row in set (0.04 sec)
```
now:
```sql
mysql> select UNIX_TIMESTAMP('2023-09-18 00:00:00','yyyy-MM-dd HH:mm:ss');
+------------+
| 1694966400 |

1b94b6368f [fix](load) in strict mode, return error for insert if datatype convert fails (#20378) 
* [fix](load) in strict mode, return error for load and insert if datatype convert fails

Revert "[fix](MySQL) the way Doris handles boolean type is consistent with MySQL (#19416)"

This reverts commit 68eb420cabe5b26b09d6d4a2724ae12699bdee87.

Since it changed other behaviours, e.g. in strict mode insert into t_int values ("a"),
it will result 0 is inserted into table, but it should return error instead.

* fix be ut

* fix regression tests

1d05feea1b [Feature](Nereids) add executable function to support fold constant for functions (#18209) 
1. Add date-time functions for fold constant for Nereids.
This is the list of executable date-time function nereids supports up to now:
- now()
- now(int)
- current_timestamp()
- current_timestamp(int)
- localtime()
- localtimestamp()
- curdate()
- current_date()
- curtime()
- current_time()
- date_{add/sub}(),{years/months/days/hours/minutes/seconds}_{add/sub}()
- datediff()
- {date/datev2}()
- {year/quarter/month/day/hour/minute/second}()
- dayof{year/month/week}()
- date_format()
- date_trunc()
- from_days()
- last_day()
- to_monday()
- from_unixtime()
- unix_timestamp()
- utc_timestamp()
- to_date()
- to_days()
- str_to_date()
- makedate()

2. solved problem:
- enable datev2/datetimev2 default.
- refactor Nereids foldConstantOnFE and support fold nested expression.
- separate the executable into multi-files for easily-reading and adding new functions

e009c459bf [enhancement](planner) remove date function if its child's type is date (#18593) 
if we have expr like below
```
date(c1) -- c1's type is date or datev2
```
the expr's result is exactly same with c1, and we should
remove date function. This expr optimization will simplify
expr, speed up execution and increase the opportunity of
push filters to storage layer.
