hi,

i found a strange bug in mysql 4.0.15-log, the server accepts queries
with bad syntax. see example. i think for limit1 (without space)
should come some error message. or?

how to repeat:
mysql> use mysql
Database changed
mysql> select Host from user limit1;
+-----------+
| Host |
+-----------+
| % |
| test |
| localhost |
| localhost |
+-----------+
4 rows in set (0.00 sec)

mysql> select Host from user limit 1;
+------+
| Host |
+------+
| % |
+------+
1 row in set (0.00 sec)

Why do you think it it is a bug?

select * from yourtable limit1 is ok - limit1 is an alias for tablename

like
select limit1.* from yourtable limit1

Hello Attila,

It's not a bug actually, see below.

AS> how to repeat:

AS> Database changed
mysql>> select Host from user limit1;
This query is interpreted as follows:
select
`Host`
from
`user` as `limit1`

i.e. `limit1` now is alias to `user` table.
since `limit1` is not a reserved word in SQL, query won't fail.
