Question

我有一个ctl文件来使用sqlldr，但是表达式的长度大于258，并且我在查询中可以获得的最小长度是不可能创建一个字符较少的查询。

我的ctl是：

OPTIONS (PARALLEL=TRUE, SILENT=(HEADER,FEEDBACK), ERRORS=1000000)
LOAD DATA
INFILE 'file.csv'
--BADFILE 'file.bad'
APPEND INTO TABLE table1
FIELDS TERMINATED BY "|"
TRAILING NULLCOLS
(
  id_user CONSTANT 2,
  number_user ,
  FULL_TIMESTAMP  date "YYYY-MM-DD HH24:MI:SS",
  id_date ,
  id_time ,
  pn BOUNDFILLER,
  service_name EXPRESSION "select service_name from pack_table where service_name in (select service_name from table_2 where id_number in (select id_number from table_3 WHERE id_user=2 and (id_date between to_char(to_date(:id_date,'YYYYMMDD')-1,'YYYYMMDD') and :id_date) and number_user= :number_user))",
  bill_response ,
  joined CONSTANT 0
)

Oracle告诉我表达式的最大长度为258 =（

我无法更改表格列的名称。

我的想法是使用其他表达式BOUNDFILLER，但它不适用于我='（

OPTIONS (PARALLEL=TRUE, SILENT=(HEADER,FEEDBACK), ERRORS=1000000)
LOAD DATA
INFILE '_INFILE_'
--BADFILE '_INFILE_.bad'
APPEND INTO TABLE table1
FIELDS TERMINATED BY "|"
TRAILING NULLCOLS
(
  id_user CONSTANT _MNO_,
  number_user ,
  FULL_TIMESTAMP  date "YYYY-MM-DD HH24:MI:SS",
  id_date ,
  id_time ,
  pn BOUNDFILLER,
  ic "select id_number from (select id_number from table_3 WHERE id_user=2 and (id_date between to_char(to_date(:id_date,'YYYYMMDD')-1,'YYYYMMDD') and :id_date) and number_user= :number_user order by id_date asc) where rownum=1" BOUNDFILLER,
  service_name EXPRESSION "select service_name from pack_table where service_name in (select service_name from table_2 where id_number = :ic)",
  bill_response ,
  joined CONSTANT 0
)

我不知道我能做些什么。

谁能帮帮我？
