上面都一样，下面是这样的

如果在plsql里执行。要用命令窗口，不要用sql窗口执行（可能会有一些编码问题。）

ORGANIZATION external
(
  TYPE oracle_loader
  DEFAULT DIRECTORY ORA_DIR
  ACCESS PARAMETERS
  (
    RECORDS DELIMITED BY 0x'214023' CHARACTERSET ZHS16GBK
    skip 1
    date_cache=0
    BADFILE 'ENTRY_WORKFLOW.bad'
    LOGFILE 'ENTRY_WORKFLOW.log'
    READSIZE 99999999
    FIELDS TERMINATED BY "~#!" LDRTRIM
    MISSING FIELD VALUES ARE NULL
    REJECT ROWS WITH ALL NULL FIELDS
    (……

external 代表外部表

ORA_DIR 表空间，select * from dba_data_files可以找到对应的目录。

 ……  里面的内容可以写一个ctl

load data
infile  'D:databag01EXTERNAL_ENTRY_WORKFLOW.TXT' "str X'214023'"
TRUNCATE into table ENTRY_WORKFLOW
fields terminated by '~#!'
trailing nullcols
(
ENTRY_ID,
STEP_ID,
CREATE_DATE DATE "yyyy-mm-dd hh24:mi:ss",
PROC_POS,
STATUS_CODE,
PROC_ER,
PROC_RESULT,
PREV_POS,
PREV_ER,
RECHK_MARK,
RECHK_COMM
)

然后用命令去执行ctl，指定一个log，然后从日志里直接复制出来放到……里就行了。
