在Oracle SQL（第2部分）中，如果表A中的日期介于表B中的日期之间，如何连接这两列？

这个问题是对我之前写的一个问题的修改：

@戈登林诺夫帮我满意地回答了这个问题

现在，我需要帮助对前面的问题进行调整。对上一个问题的修改是，我在表A中又添加了两行：与Joe Bryant和Jennifer Smith对应的行

因此，我有以下两个表表a和表B：

表A：

+-----------------+--------------+---------------+-------------+

| 5/22/2020 9:44  | Toyota Camry | 894A839       | Jennifer Smith |

表B：

我想以一种方式将两个表按车牌连接起来，其中表a中的日期和表B中的日期符合以下标准：
