Question

我有一个脚本应该打开一个xml文件并读取内容并进行处理。已成功创建plsql过程TEST_LOAD.BOB_LOAD。

TEST_LOAD.BOB_LOAD如下所示：

PROCEDURE BOB_LOAD(p_uuid IN varchar2,
      xml_in IN  xmltype,
      msg_status OUT varchar2,
      xml_out OUT xmltype);

END  BOB_LOAD;
/

下面的脚本在最后一行调用此过程，似乎是错误的原因。我假设它没有将变量x识别为XMLTYPE。

DECLARE
    xml_file UTL_FILE.FILE_TYPE;
    chars_read INTEGER;
    xml_clob CLOB;
    xamount INTEGER :=32767;
    char_buffer VARCHAR2(32767);
    x XMLType;
BEGIN
xml_file := utl_file.fopen('/export/hm/testpit/bob', 'test.xml', 'r', xamount);
   DBMS_LOB.CREATETEMPORARY(xml_clob, true);
 LOOP
 BEGIN
 UTL_FILE.GET_LINE(xml_file, char_buffer);
    chars_read :=LENGTH(char_buffer);
   DBMS_LOB.WRITEAPPEND(xml_clob, chars_read, char_buffer);
   DBMS_LOB.WRITEAPPEND(xml_clob, 1, CHR(10));
   EXCEPTION
   WHEN NO_DATA_FOUND THEN
   EXIT;
   END;
   END LOOP;
  UTL_FILE.FCLOSE(xml_file);
  x := XMLType.createXML(xml_clob);
  TEST_LOAD.BOB_LOAD('9718fa05-9995-4f17-jk1k-763113b8f4a4', x );
 END;
 /

然而，当我运行上面的脚本时，我得到一个ORA-06550，PLS：00306错误说：

ORA-06550: line 39, column 3:
PLS-00306: wrong number or types of arguments in call to 'BOB_LOAD'
ORA-06550: line 39, column 3:
PL/SQL: Statement ignored

您的程序有4个参数。你只用它调用它。你需要用out参数调用它。

将文件内容读入CLOB的更简单方法：

function read_clob_from_file(p_directory    varchar2
                               ,p_filename varchar2) return clob is

      l_amt        number := dbms_lob.lobmaxsize;
      l_dst_loc    clob;
      l_dst_offset number := 1;
      l_lang_ctx   number := dbms_lob.default_lang_ctx;
      l_src_loc    bfile;
      l_src_offset number := 1;
      l_warning    number;
   begin

      l_src_loc := bfilename(p_directory, p_filename);
      dbms_lob.createtemporary(l_dst_loc, true);
      dbms_lob.fileopen(l_src_loc, dbms_lob.file_readonly);
      dbms_lob.loadclobfromfile(l_dst_loc
                               ,l_src_loc
                               ,l_amt
                               ,l_dst_offset
                               ,l_src_offset
                               ,dbms_lob.default_csid
                               ,l_lang_ctx
                               ,l_warning);
      dbms_lob.fileclose(l_src_loc);
      return l_dst_loc;
   end;

脚本无法将XMLTYPE参数传递给PLSQL过程
