Oracle SQL*加载程序时间戳为错误

我的控制文件是

ACCESS_TIME TERMINATED BY "" "TO_TIMESTAMP_TZ(:ACCESS_TIME,'YYYY/MM/DD HH24:MI:SS:FF TZR')"

数据文件是

2012/11/12 15:18:00:765 CST

但是，当我运行SQL*Loader提交数据时，数据库访问时间与数据文件不匹配

2012/11/13 05:18:00:765000000

做一个：

---

在中央标准时间插入数据。当您选择数据时，它可能会显示在您的会话（本地）时区中。

如果您看到这种行为，则表列必须是带有本地时区的时间戳，并且您在新加坡等地（gmt+8），例如：

如果希望保留CST部分而不转换它，则将表定义为带时区的时间戳
