将附件正确传递给UTL_MAIL.SEND_ATTACH_RAW

Question

假设我有两个文件名相同的文件sample.xlsx 在两个单独的目录u1\data\out1\和u2\data\out2\中 这两个目录已分别作为DBA_DIRECTORIES和EXT_OUT1分配到EXT_OUT2。

我想使用sample.xlsx从EXT_OUT1发送UTL_MAIL.SEND_ATTACH_RAW， 如何将其正确传递给attachment参数？

示例匿名阻止（注释注释）：

DECLARE

    vInHandle       utl_file.file_type;
    l_sender        varchar2(100)   := 'SO@SO.com';
    l_recipients    varchar2(100)   := 'migs.isip.23@gmail.com';
    l_subject       varchar2(100)   := 'Employee Roster Report';
    l_message       varchar2(100)   := 'Hello';
    l_attachment    raw;
    l_directory     varchar2(100)   := 'EXT_OUT1';
    fname           varchar2(100)   := 'sample.xlsx';


BEGIN

    /* how put RAW data into l_attachment here? */
    --vInHandle := utl_file.fopen(l_directory, fname, 'R'); -- If i'm not mistaken, this reads the File from the specified directory
    --utl_file.get_raw();                                   -- not sure what parameters i should pass
    --utl_file.fclose(vInHandle);                           -- ?

    UTL_MAIL.SEND_ATTACH_RAW
    (
        sender       => l_sender
    ,  recipients   => l_recipients
    ,  subject      => l_subject
    ,  message      => l_message
    ,  attachment   => l_attachment
    ,  att_filename => 'clouds.jpg'
    );

END;

附件内容是您作为附件参数提供的值。文件名只是一个标签。它不会读取文件，因此您必须自己执行此操作，然后将其指定为附件。
