New in squeak and mysql

In squeak when a try to execute:
'insert into table person (name, dt) values('foo', '2005-1-1')' -OK
'SELECT LAST_INSERT_ID()'- OK ( I think the problem is here)
select * from Person; - I received an error MessageNotUnderstood:
UdefinedObject>> asInteger
Originated from:
JdmConnection>>executeQuery: aQuery
...
JdmConnection>>readName:

I am using win2000.

Thanks.
