Oracle SQLLDR - 使用参数文件指定多个日志、dsc、坏文件

Oracle SQLLDR - Using parameter file to specify multiple log, dsc, bad files

我不确定如何处理这种使用 Oracle SQLLDR 将文件加载到单个 table 中的情况。 我有多个 infiles,我可以毫无问题地加载它们。但是,我想在我的参数文件中为每个日志文件、错误文件和丢弃 directories/files 指定。这可能吗?我试过将它们列在参数文件中,文件名之间有空格,但这似乎不起作用。我在任何地方都找不到有关如何执行此操作的说明或示例。

我使用命令包含参数文件:

sqlldr user/password@pdbxxxxx PARFILE=/directory/parameter_file.par

我的参数文件示例:

    CONTROL=/directory/control_file.ctl
    LOG=/directory/log_file.log
    BAD=/directory/bad_file.bad
    DISCARD=/directory/discard_file.dsc
    DISCARDMAX=100000000
    DATA=/directory/data_file-01.csv
    DIRECT=FALSE

我的控制文件示例:

load data
infile '/directory/data_file-01.csv'
infile '/directory/data_file-02.csv'
infile '/directory/data_file-03.csv'
APPEND INTO TABLE my_table
                fields terminated by "," optionally enclosed by '"'
                TRAILING NULLCOLS
  (
        col1 CHAR
    ,   col2 CHAR                  
    ,   col3 CHAR
)

看起来像 Specifying multiple data files,如文档中所述。

摘录:

To load data from multiple data files in one SQL*Loader run, use an INFILE clause for each data file.

You can also specify a separate discard file and bad file for each data file. In such a case, the separate bad files and discard files must be declared immediately after each data file name.

举几个例子:

INFILE  mydat1.dat  BADFILE  mydat1.bad  DISCARDFILE mydat1.dis 
INFILE  mydat2.dat 
INFILE  mydat3.dat  DISCARDFILE  mydat3.dis
