Seems that either I don't understand mysql, or something.
My table, with the non-important things removed...
mysql> explain plate;
+---------+-----------------------+------+-----+---------------------+----------------+
| Field | Type | Null | Key | Default | Extra
|
+---------+-----------------------+------+-----+---------------------+----------------+
| pid | mediumint(8) unsigned | | PRI | NULL |
auto_increment |
| year | year(4) | YES | | NULL |
|
[...]
So my assumption is that if I insert with year="" it should use the
default. Or at least 0000.
mysql> update plate set year=NULL where pid=65;
Query OK, 1 row affected (0.00 sec)
Rows matched: 1 Changed: 1 Warnings: 0
mysql> select * from plate where pid=65;
+-----+---------+------+-
| pid | plate | year |
+-----+---------+------+-
| 65 | DVF0343 | NULL |
+-----+---------+------+-
But if I do this:
mysql> update plate set year="" where pid=65;
Query OK, 1 row affected (0.01 sec)
Rows matched: 1 Changed: 1 Warnings: 1
mysql> select * from plate where pid=65;
+-----+---------+------+-
| pid | plate | year |
+-----+---------+------+-
| 65 | DVF0343 | 2000 |
+-----+---------+------+-
2000? What? Why? Confused. PHP or Mysql fault?
