Question

我对使用SQL很陌生，所以如果这是一个简单的错误，我很抱歉。基本上我需要将一些数据加载到表中。但是，当我尝试使用sql loader将数据插入表中时，它不会被插入，但是没有错误表明出现了任何问题。

表：

create table Test(var char(3), var2 char(10), var3 number(7,2), 
var4 char(3),primary key (var));

这是我的控制文件（Test1.ctl）：

LOAD DATA
INFILE *
REPLACE INTO TABLE Test
FIELDS TERMINATED BY "," OPTIONALLY ENCLOSED BY "'" TRAILING NULLCOLS
(var, var2, var3, var4 terminated by whitespace)
BEGINDATA
'123','test',12345,'321'
'321','test2',54321,null

我也尝试使用单独的.csv文件来加载数据而不是BEGINDATA，但两种方法都会发生同样的事情。

当我尝试加载数据时，从命令提示符开始，会发生这种情况：

[******** ~]$ sqlldr user_name Test1.ctl
Password:******

SQL*Loader: Release 10.2.0.3.0 - Production on Sun Mar 26 14:01:21 2017

[******** ~]$

然后当我去sqlplus检查表时，它是空的。

SQL> desc Test;
Name                                      Null?    Type
----------------------------------------- -------- -------------------------
VAR                                       NOT NULL CHAR(3)
VAR2                                               CHAR(10)
VAR3                                               NUMBER(7,2)
VAR4                                               CHAR(3)

SQL> select * from Test;

no rows selected

SQL>

我无法弄清楚为什么它不会被加载到桌面上。

感谢您的帮助！

版本10是一个非常古老的版本！

我无法在12c中重现您的问题。你应该加载一行;第二行失败，因为它试图加载字符串＆＃34; null＆＃34;这是CHAR（3）

中的4个字符
