Oracle:external table 抛出异常

Question

我正在尝试执行此脚本，该脚本为我在数据库之外的文件创建外部 table。脚本如下：

DECLARE

FILENAME VARCHAR2 := 'actual_data.txt';

BEGIN
EXECUTE IMMEDIATE 'CREATE TABLE ACTUAL_DATA_1 (
  ID      NUMBER(5),
  MSISDN    VARCHAR2(20),
  RECHARGE_DATE DATE,
  RECAHRGE_AMOUNT  NUMBER(25)
)
ORGANIZATION EXTERNAL (
  TYPE ORACLE_LOADER
  DEFAULT DIRECTORY USER_DIR
  ACCESS PARAMETERS (
    RECORDS DELIMITED BY NEWLINE
    FIELDS TERMINATED BY ','
    MISSING FIELD VALUES ARE NULL
    (
  ID      NUMBER(5),
  MSISDN    VARCHAR2(20),
  RECHARGE_DATE DATE,
  RECAHRGE_AMOUNT  NUMBER(25)
    )
  )
  LOCATION (''' || FILENAME || ''')
)
PARALLEL 5
REJECT LIMIT UNLIMITED;';
END;
/

但是我收到了这个错误：

FIELDS TERMINATED BY ','

                          *
ERROR at line 17:
ORA-06550: line 17, column 27:

) , * & | = - + < / > at in is mod remainder not rem => ..

有人可以帮助 oracle 新手吗？

Answer 1

请指定 VARCHAR2 定义的强制大小。

文件名 VARCHAR2(n) := 'actual_data.txt';

而 n 可以介于 1 .. 32767 示例：文件名 VARCHAR2(400) := 'actual_data.txt';
