DECLARE @vcDB varchar(20),@vcSchema varchar(20),@vcTable varchar(200)

Select @vcDB='mydb',@vcSchema='dbo'

DECLARE cLoop cursor for
select TABLE_NAME
from INFORMATION_SCHEMA.TABLES
where TABLE_CATALOG=@vcDB
and TABLE_SCHEMA=@vcSchema
order by TABLE_NAME ASC

open cLoop

FETCH NEXT FROM cLoop INTO @vcTable
WHILE @@FETCH_STATUS=0
BEGIN
if not exists (SELECT *
FROM INFORMATION_SCHEMA.TABLE_CONSTRAINTS
WHERE TABLE_SCHEMA = @vcSchema
AND TABLE_NAME = @vcTable
AND CONSTRAINT_TYPE = 'PRIMARY KEY')
print @vcTable + ' does not have a primary key'

FETCH NEXT FROM cLoop INTO @vcTable
END
Close cLoop
DEALLOCATE cLoop
