Javascript 对于函数中的默认日期参数，我必须在Oracle中签入哪个数据库参数？

我有以下奇怪的问题。我有以下程序，在一个包中：

PROCEDURE createSmth (p_param1        IN     VARCHAR2,
                      p_param2        IN     NUMBER,
                      p_param3        IN     DATE,
                      p_param4        IN     DATE,
                      p_description   IN     VARCHAR2,
                      p_last_login    IN     VARCHAR2 DEFAULT NULL,
                      o_sid           OUT    NUMBER,
                      p_ret           OUT    NUMBER,
                      p_mess          OUT    VARCHAR2);

调用此过程的应用程序正在使用oracledb:^4.2.0。 以下是为便于阅读而格式化的开发日志：

DBService: calling stored procedure 'BEGIN pkg.createSmth(
:p_param1, 
:p_param2, 
:p_param3, 
:p_param4, 
:p_description, 
:p_last_login, 
:o_sid, 
:p_ret, 
:p_mess); END;'

在dev和prod上，IN参数的oracledb类型都设置为STRING

执行select sysdate from dual在两个数据库上返回相同的日期格式：16-JUN-20

因此，任何关于解决此问题的提示都将不胜感激。

导致此错误的原因可能很多。例如，它可以是NLS_DATE_格式参数，也可以是TO_DATE函数中的格式参数

您需要分析代码来修复此问题

例如：

SQL> show parameter nls_date_format

NAME                     TYPE    VALUE
------------------------------------ ----------- ------------------------------
nls_date_format              string  DD/MM/YYYY
SQL> select to_date('06/16/2020') from dual;
select to_date('06/16/2020') from dual
               *
ERROR at line 1:
ORA-01843: not a valid month


SQL> select to_date('16/06/2020') from dual;

TO_DATE('1
----------
16/06/2020

SQL> 

而不是2020年6月1日使用

截止日期：2020年6月1日、年月日或

日期“2020-06-01”-日期文字

要了解会话/数据库使用的日期格式，可以使用NLS_会话_参数或NLS_数据库_参数视图参数名称：NLS_日期_格式。但建议使用带有to_date或date literal的特定格式，因为NLS_date_格式可能会随着时间的推移而改变，并且代码将无法工作。

如果过程需要日期，请不要提供字符串

这是字符串：

'01/06/2020'

以下是日期：

date '2020-06-01'
to_date('01/06/2020', 'dd/mm/yyyy')

---

选择一个最适合你的选项；如果您总是传递没有时间组件的日期，则始终采用日期“yyyy-mm-dd”格式的日期文字就可以了。若你们想打发时间，那个么使用合适的格式掩码的to_date可能是一个更好的选择。

过程参数是date。oracle数据库类型为字符串。对于节点oracledb类型和Oracle类型之间的映射，请检查是否在dev中不使用它们中的任何一个，并且它在dev中的工作方式应与在dev中的工作方式相同，会话使用的NLS_DATE_格式必须是dd/mm/yyyy，这与Prod不同，因此您在Prod中面临问题。这就是为什么建议始终使用to_DATE或DATE文本来创建答案中提到的日期。
