ORA-01843不是有效的月份-比较日期

Question

我在尝试从按日期筛选的表中选择数据时遇到了一个问题。

例如：

SELECT * FROM MYTABLE WHERE MYTABLE.DATEIN = '23/04/49';

Informe de error:
Error SQL: ORA-01843: mes no válido
01843. 00000 -  "not a valid month"
*Cause:    
*Action:

null

此选择select*from nls_session_parameters；的结果是：

PARAMETER                      VALUE

Answer 1

您应该使用to_date函数(oracle/functions/to_date.php)

SELECT * FROM MYTABLE WHERE MYTABLE.DATEIN = TO_DATE('23/04/49', 'DD/MM/YY');
