有两个局部断言。
为了查看这两个局部断言的实际计数，生成一个count查询。
For the two local predicates, to see what the real count is, generate a count query.
因为该NLJOIN的outer即t BS CAN(2)应用于局部断言，必须将该断言增加到计数查询。
Since the OUTER of this NLJOIN, TBSCAN (2), is applying local predicates, you must also add the predicates to the count query.
