No data to FETCH warning

[Laurent]

Using the client I execute the following command

mysql> select * from artefacttype where name like 'project' //
+----------------+---------+
| ArtefactTypeId | Name |
+----------------+---------+
| 2 | project |
+----------------+---------+
1 row in set (0.00 sec)

When I execute a stored procedure containing the following code

select ArtefactTypeId into TypeId
from ArtefactType
where Name like 'project';

I get the warning "No data to FETCH ".

Why do I see a difference in behaviour between mysql cmd line and stored procedure?
