Answer 1

当您将输入字符串'01-OCT-19 00:00:00'转换为日期时，您将面临问题。默认情况下，它使用会话的NLS_DATE_FORMAT将字符串转换为日期，如果提供的字符串和NLS_DATE_FORMAT不匹配，则会引发此错误。

更好的方法是使用TO_DATE函数或DATE文字将字符串转换为日期，如下所示：

Replace '01-OCT-19 00:00:00' with -> DATE '2019-10-01'
-- OR --
Replace '01-OCT-19 00:00:00' with -> TO_DATE('01-OCT-19 00:00:00','DD-MON-RR HH24:MI:SS')

干杯！

Answer 2

在'01 -OCT-19 00:00:00'和SYSDATE之间设置AND TNOT_CREATED_DATIM

'01-OCT-19 00:00:00'是 STRING 文字，而不是 DATE 。与日期比较时，必须始终将其明确转换为DATE数据类型。在您的情况下，我希望使用 ANSI日期文字：

AND TNOT_CREATED_DATIM BETWEEN DATE '2019-10-01' and SYSDATE

ANSI日期文字不包含任何时间部分，并且必须严格按照此格式('YYYY-MM-DD')指定。如果您有时间部分，请使用TO_DATE：

TO_DATE('01-OCT-19 00:00:00','DD-MON-RR HH24:MI:SS')

Oracle DATE值的默认日期格式由初始化参数 NLS_DATE_FORMAT 指定。
