Is this a bug of stored procedure?

[tom soyer]

Hi,

I tried to pass the name of a table into a procedure and use that in a
select statement. Somehow it doesn't work. Here is the code:

create procedure sp3(in tablename varchar(10))
begin
select count(*) from tablename;
end$

When the procedure is called, I got the following error: ERROR 1146 (42S02):
Table 'test.tablename' doesn't exist.

Does anyone know why my code generated an error? Is this a bug?

Thanks,

Tom
