【中文标题】ORA-29280 Oracle SQL 开发人员在尝试将表内容导出为 csv 时出错

【英文标题】：ORA-29280 Oracle SQL developer error while trying to export table content as a csv

【发布时间】：2020-10-06 16:45:18

【问题描述】：

create or replace procedure EXPORTTABLECONTENT is
    file_handle UTL_FILE.file_type;
begin
    file_handle := utl_file.fopen('CSV_DIR', 'csv.csv', 'w');
  for i in (
    select * from kwapp.minirules@ESDEV -- your query here
  ) loop
    utl_file.put_line(file_handle, 
      i.RULEINDEX || ',' || i.RULENAME
    );
  end loop;
  utl_file.fclose(file_handle);
end EXPORTTABLECONTENT;

我正在尝试从 minirules@ESDEV 导出表格内容，但由于某种原因我收到以下错误：

Connecting to the database EPS_ESDEV.
ORA-29280: invalid directory object
ORA-06512: at "SYS.UTL_FILE", line 41
ORA-06512: at "SYS.UTL_FILE", line 478
ORA-06512: at "AJ185194.EXPORTTABLECONTENT", line 4
ORA-06512: at line 2

【问题讨论】：

您真的可以访问名为“CSV_DIR”的目录吗？

【参考方案1】：

您不能使用任何目录名称，只能使用您可以使用的目录名称之一。见

SQL> select * from all_directories;

OWNER DIRECTORY_NAME  DIRECTORY_PATH
----- --------------- ---------------
SYS   EXT_DIR         c:\temp

使用您的代码（稍作修改以便在我的数据库中编译）：

SQL> create or replace procedure exporttablecontent is
  2    file_handle utl_file.file_type;
  3  begin
  4    file_handle := utl_file.fopen('CSV_DIR', 'csv.csv', 'w');
  5
  6    for i in (select * from dept) loop
  7      utl_file.put_line(file_handle, i.deptno || ',' || i.dname);
  8    end loop;
  9    utl_file.fclose(file_handle);
 10  end exporttablecontent;
 11  /

Procedure created.

SQL> exec exporttablecontent;
BEGIN exporttablecontent; END;

*
ERROR at line 1:
ORA-29280: invalid directory path

ORA-06512: at "SYS.UTL_FILE", line 478
ORA-06512: at "SCOTT.EXPORTTABLECONTENT", line 4
ORA-06512: at line 1

但是，如果我使用我可用的目录（即SYS 授予我read/write 权限）：

SQL> create or replace procedure exporttablecontent is
  2    file_handle utl_file.file_type;
  3  begin
  4    file_handle := utl_file.fopen('EXT_DIR', 'csv.csv', 'w');       --> here
  5
  6    for i in (select * from dept) loop
  7      utl_file.put_line(file_handle, i.deptno || ',' || i.dname);
  8    end loop;
  9    utl_file.fclose(file_handle);
 10  end exporttablecontent;
 11  /

Procedure created.

SQL> exec exporttablecontent;

PL/SQL procedure successfully completed.

SQL>

它工作（如预期）。

SYS 如何授予目录权限？像这样：

SQL> connect sys as sysdba
Enter password:
Connected.
SQL> grant read, write on directory ext_dir to scott;

Grant succeeded.
