Oracle DML错误缺乏细节

我正在从像这样的批量插入操作中捕获错误:

begin
    --bulk insert
    forall i in v_data.first .. v_data.last save exceptions
        insert into my_filter_table values v_data (i);

    commit;

exception
    -- catch and print the saved-up DML errors.
    when X_DML_ERRORS then
        declare
            v_iteration number;
        begin
            dbms_output.put_line('');
            dbms_output.put_line('DML Errors:');
            for i in 1 .. SQL%BULK_EXCEPTIONS.count loop
                v_iteration := SQL%BULK_EXCEPTIONS(i).error_index;

                dbms_output.put_line('Iteration: '||v_iteration||' Message: '||
                                 SQLERRM(-SQL%BULK_EXCEPTIONS(i).ERROR_CODE));


            end loop;
        end;
end;

输出看起来像这样:

    Iteration: 3 Message: ORA-01400: cannot insert NULL into ()
    Iteration: 4 Message: ORA-02290: check constraint (.) violated
    Iteration: 8 Message: ORA-00001: unique constraint (.) violated

我正在收到错误的事实并没有打扰我,因为我正在测试错误处理代码。问题是Oracle错误消息没有显示约束名称,即它显示check constraint (.) violated但是这并没有告诉我违反了WHICH检查约束。

有谁知道这是怎么回事?

(Oracle版本10.2)

1 个答案:

答案 0 :(得分:6)

SQL%BULK_EXCEPTIONS(i).error_code仅保存Oracle错误号。然后,您使用sqlerrm函数来查找错误消息文本。该函数无法知道什么约束被破坏。

您可以调用sqlerrm函数,而不会抛出异常来复制结果。

begin
   dbms_output.put_Line(sqlerrm(-1400));
   dbms_output.put_Line(sqlerrm(-2290));
   dbms_output.put_Line(sqlerrm(-1));
end;

哪个输出

ORA-01400: cannot insert NULL into ()
ORA-02290: check constraint (.) violated
ORA-00001: unique constraint (.) violated

可能的解决方法是在异常处理程序中重新执行失败的语句。

表格默认:

create table t ( x number(1) primary key);

代码:

declare
   dml_errors EXCEPTION;
   PRAGMA EXCEPTION_INIT(dml_errors, -24381);
   TYPE t_nums is table of NUMBER;
   l_nums t_nums := t_nums(1,1,10);
begin
   forall i in 1..l_nums.count save exceptions
      execute immediate 'insert into t values (:x)' using l_nums(i);
exception
   when dml_errors then
      for j in 1..sql%bulk_exceptions.count
      loop
         if sql%bulk_exceptions(j).error_code = 1
         then
            begin
               execute immediate 'insert into t values (:x)'
                  using l_nums(sql%bulk_exceptions(j).error_index);
            exception
               when dup_val_on_index then
                  dbms_output.put_line(sqlerrm);
            end;
         else
            dbms_output.put_line(sqlerrm(-sql%bulk_exceptions(j).error_code));
         end if;
      end loop;
end;

哪个输出:

ORA-01438: value larger than specified precision allowed for this column
ORA-00001: unique constraint (XXXXXXXX.SYS_C00264470) violated
ORA-24381: error(s) in array DML
