当我从package_name所属的相同数据库实例和架构运行它时,我能够正常运行它.但是,当我在数据库链接上运行它时(对存储的proc名称进行必要的修改等)我得到一个oracle错误：ORA-24338：语句句柄未执行.

dblink上此代码的修改版本如下所示：

declare
       symbol_cursor  package_name.record_cursor@db_link_name;
       symbol_record  package_name.record_name@db_link_name;
begin
       symbol_cursor := package_name.function_name@db_link_name('argument');
loop
       fetch symbol_cursor into symbol_record;
       exit when symbol_cursor%notfound;
       -- Do something with each record here,e.g.:
       dbms_output.put_line( symbol_record.field_a );
end loop;

CLOSE symbol_cursor;
