导入csv文件到oracle数据库

Question

我想将 .csv 文件导入到下面的 oracle 数据库表中，但它不起作用，并且日志文件为空，没有任何输出。

我的 shell 脚本如下：

并且日志文件始终为空

下面是 .csv 文件的示例

您应该发布目标表描述；没有它，我们就必须“猜测”数据类型。我的幸运猜测（根据样本数据）：

SQL> desc test
 Name                                      Null?    Type
 ----------------------------------------- -------- ----------------------------
 SENDINGFRI                                         NUMBER
 LOGGINGTIME                                        TIMESTAMP(6)
 RENEWALNUMBER                                      NUMBER
 TRANSACTIONTYPE                                    VARCHAR2(20)
 STATUS                                             VARCHAR2(10)
 DURATION                                           VARCHAR2(20)

这可能是错误的； 

duration

列听起来好像您想将例如其中有一个数字（

需要 2 秒才能完成

），但示例数据表明您正在向其中插入一个字符串（null，在这种情况下，是一个字符串）。使用您编写的控制文件，结果是（在我的数据库中）

Record 1: Rejected - Error on table TEST, column LOGGINGTIME.
ORA-01843: not a valid month

控制文件，已修复：

---

LOAD DATA
INFILE *
REPLACE
INTO TABLE test
FIELDS TERMINATED BY ',' OPTIONALLY ENCLOSED BY '"'
TRAILING NULLCOLS
(
SENDINGFRI,
LOGGINGTIME "to_timestamp(:loggingtime, 'yyyy-mm-dd-hh24:mi:ss.ff')",
RENEWALNUMBER,
TRANSACTIONTYPE,
STATUS,
DURATION
)

begindata
22997186945,2023-07-25-00:05:56.301,23900032093333,Payment,SUCCESS,null
22951547347,2023-07-25-00:04:12.794,23900336289912,Payment,SUCCESS,null

加载会话：

SQL> $sqlldr scott/tiger@orcl control=test49.ctl log=test49.log

SQL*Loader: Release 18.0.0.0.0 - Production on Čet Kol 17 14:23:09 2023

Table TEST:
  2 Rows successfully loaded.

Check the log file:

for more information about the load.

结果：

SQL> select * from test;

   SENDINGFRI LOGGINGTIME                  RENEWALNUMBER TRANSACTIONTYPE      STATUS     DURATION
------------- ------------------------- ---------------- -------------------- ---------- --------------------

好的；数据在这里。

我建议您首先正确完成这部分工作（即加载自身），然后创建一个 shell 脚本。我对此无能为力，我不使用任何类型的 Unix 操作系统。
