请帮助我解决此错误。

Answer 1

该错误消息是因为从数据文件读取的数据大于sqlldr的默认字符缓冲区255，如果未指定CHAR和大小，则使用该默认字符缓冲区。请注意，这不同于字段所对应的列的大小。例如，如果我有一个VARCHAR2（4000）的表列，但未在控制文件中明确给出大小

cola  not null,

并且数据文件中的数据超过255但长度小于4000，则会收到错误消息。

但是，如果控制文件按如下所示声明缓冲区大小：

cola char(4000) not null,

就像创建一个更大的缓冲区（此处与列大小匹配）一样，一切都会很好。因此，养成始终包括列大小的习惯。为自己节省一些麻烦，并创建一个函数为您生成默认控制文件...等我为您发布我的文件后，尝试一下：https : //stackoverflow.com/a/37947714/2543416

Answer 2

在你的控制文件中使用CHAR(NN)长度超过 255 的列。所以你的控制文件应该像这样；

LOAD DATA
INFILE '$IN_DIR/$FILENAME'
BADFILE '$REJ_DIR/$FILENAME.bad'
APPEND
INTO TABLE test
FIELDS TERMINATED BY ","
TRAILING NULLCOLS
  (
   FILE_RECORD_DESCRIPTOR               POSITION(1),
   LINE_NO                              FILLER,
   DEPT                                 TERMINATED BY "\n",
   SEQ_NO                               CONSTANT "1",
   DEPT_NO                              CHAR(4000),
   STATUS                               CONSTANT "U",
   PROCESS_ID                           CONSTANT "2"
  )

我不知道如何使用CHAR(4000)with CONSTANT "0"。但这应该可以解决问题。
