我有一张简单的table

CREATE TABLE MYTABLE
   (    
    MYDATE DATE,
    ID NUMBER
   )

MYDATE的默认格式为'dd-MON-yy'

使用匹配的日期格式插入工作没有任何问题

INSERT INTO mytable values ('01-JAN-01',1)

以及SQL加载器

LOAD DATA
INFILE "mytable.dat" "str '#@n'"
INTO TABLE mytable TRUNCATE
FIELDS TERMINATED BY '&,#' TRAILING NULLCOLS
(MYDATE ,ID)

.dat文件

01-JAN-01&,#1#@

当插入日期的日期格式不是默认的(我需要)时出现问题，然后我得到ORA-01861: literal does not match format string，因此我使用TO_DATE，它适用于INSERT

INSERT INTO mytable values (TO_DATE('1901-02-01 00:00:00','YYYY-MM-DD HH24:MI:SS'),2)

但由于某些原因，不适用于SQL Loader

.dat文件

TO_DATE('1901-02-01 00:00:00','YYYY-MM-DD HH24:MI:SS')&,#2#@

我不确定我是错过了这里的某些语法，还是SQL Loader的某些限制。
