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)
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
