使用外部表将数据加载到 Oracle 11g R2 时出现以下错误。

NLS_DATE_FORMAT : DD/MM/RRRR

注意：我尝试了以下无济于事：

DATE_M DATE "dd.mm.yyyy",

DATE_M CHAR date_format DATE mask "DD/MM/RRRR"

首先，您需要在单引号内指定日期格式掩码，而不是双引号。

其次，这相当令人困惑，您为“AMOUNT”列指定的格式不正确。当您说数据是“DECIMAL”时，您实际上是在输入文件中指定二进制格式。您应该在访问参数中为 FIELD 定义指定字符，并让 Oracle 将字段转换为数字。我很少（如果有的话）使用除 CHAR 以外的任何格式来描述 SQL*Loader 或外部表中的输入数据。就是说，但是，您有点卡在这里，因为我认为您不能在外部表定义中指定十进制字符（在您的情况下为“，”）。您只能通过 NLS 实例参数更改它。

这是我为使您的示例正常工作所做的（注意：10g 数据库）：

CREATE TABLE TABLE_EXT ( "COMPANY" VARCHAR2(101)
                      ,  "COMPANY_VN" VARCHAR2(15)
                      ,  "IL" VARCHAR2(17)
                      ,  "TERMINAL" VARCHAR2(8)
                      ,  "T_NO" VARCHAR2(15)
                      ,  "NAME" VARCHAR2(108)
                      ,  "SNAME" VARCHAR2(50)
                      ,  "REF_NO" VARCHAR2(23)
                      ,  "AMOUNT" NUMBER(15,2)
                      ,  "DATE_M" DATE
                      ,  "TIME_M" VARCHAR2(11)
                      ,  "TEL_NO" VARCHAR2(25)
                      ,  "ADDRESS" VARCHAR2(50) )

          ( TYPE ORACLE_LOADER 
            DEFAULT DIRECTORY external_tables 
            ACCESS PARAMETERS 
               ( RECORDS DELIMITED BY NEWLINE 
                  FIELDS TERMINATED BY '|' 
                  MISSING FIELD VALUES ARE NULL 
                 ( COMPANY
                 , COMPANY_VN
                 , IL
                 , TERMINAL
                 , T_NO
                 , NAME
                 , SNAME
                 , REF_NO
                 , AMOUNT 
                 , DATE_M CHAR date_format DATE mask 'dd.mm.yyyy'
                 , TIME_M
                 , TEL_NO
                 , ADDRESS ) ) 
            LOCATION ('TABLE_EXT.txt') )  
            REJECT LIMIT 10 ;

我稍微修改了您的数据以将您的十进制字符更改为“。” 在数据中：

这对我有用。

底线，我认为您需要（1）修改您的数据，（2）修改您的实例 NLS 参数以更改十进制字符或（3）将您的数据加载为字符并在顶部的视图中使用 TO_NUMBER 函数外部表。
