这是我的过程，我正在过滤4个参数的数据库：
开始日期，结束日期，小时和分钟。
当我在2017-11-01至2017-11-30之间过滤数据（在一个月内）其工作正常，但当我过滤数据超过1个月如2017-11-01至2017-12-10那么它给我的错误如下所示。

错误
ORA-06502：PL / SQL：数字或值错误
ORA-06512：at＆＃34; MYRENT.RENTEDTOTALCARS＆＃34;，第58行
ORA-06512：第13行
My Line no 58 in procedure is：

答案 0 :(得分：0)
这就是我的意思：我注释了OUT参数以及OPEN语句，并包含了DBMS_OUTPUT。

我无法运行它，因为我没有你的桌子，但你可能会尝试这样做。注意DATE格式 - 它是DD.MM.YY.也许您需要将转换为有效的日期格式 - 这取决于您的NLS设置。 最安全的方式是明确地将其设为DATE文字（始终为DATE 'YYYY-MM-DD'），或使用适当格式掩码的TO_DATE。
