Question

发生异常时，我有问题要引起注意。可以说我的查询有两个inserts语句。

      do $$       
      begin
        insert into ...
        insert into ...
      exception when others then 
        raise notice '% %', SQLERRM, SQLSTATE;
      end; $$ 
      language 'plpgsql';

我想返回错误消息和代码。目前没有任何反应。如果删除了'notice'％％'，SQLERRM，SQLSTATE;' 然后引发错误，但我需要抓住它。似乎“通知”无效。这就是我的回应

{"command":"BEGIN","rowCount":null,"oid":null,"rows":[],"fields":[],"_parsers":[],"RowCtor":null,"rowAsArray":true}
{"command":"LOCK","rowCount":null,"oid":null,"rows":[],"fields":[],"_parsers":[],"RowCtor":null,"rowAsArray":true}
{"command":"DO","rowCount":null,"oid":null,"rows":[],"fields":[],"_parsers":[],"RowCtor":null,"rowAsArray":true}
{"command":"COMMIT","rowCount":null,"oid":null,"rows":[],"fields":[],"_parsers":[],"RowCtor":null,"rowAsArray":true}

Postgres 9.4

引发通知'％％'，SQLERRM，SQLSTATE不起作用
