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,数据库中的 ACCESS_TIME 与数据文件不匹配。

做一个:
select SESSIONTIMEZONE from dual;
您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,那么表格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:
SQL> alter session set time_zone='+08:00';
Session altered.
SQL> create table test (access_time timestamp with local time zone);
Table created.
SQL> host sqlldr test/test control=/tmp/load.ctl log=/tmp/load.log

如果您想保留 CST 部分而不转换它,则将您的表定义为 TIMESTAMP WITH TIME ZONE。
SQL> create table test (access_time timestamp with time zone);
Table created.
SQL> host sqlldr test/test control=/tmp/load.ctl log=/tmp/load.log
