 Ver 11.15 Distrib 3.23.40, for unknown-freebsdelf4.3 (i386)

mysql> create table test (id int, name varchar(255) primary key);
Query OK, 0 rows affected (0.02 sec)

mysql> insert into test values (1,'lalala'), (2,'bebebe'),(3,' name ');
Query OK, 3 rows affected (0.01 sec)
Records: 3  Duplicates: 0  Warnings: 0

mysql> select * from test where name like '%name%';
+------+-------+
| id   | name  |
+------+-------+
|    3 |  name |
+------+-------+
1 row in set (0.00 sec)

mysql>
Так что ненормально.

WBR,
