Question

如何定义更新触发器函数以更新主表中已定义分区的记录。我有一个在其上定义了分区的表和插入触发器函数的代码，只要主表中有插入，它就会在子表中插入数据。代码I＆＃39;如下：

    --Master table
        CREATE TABLE "SMS_RECEIPT"
        (
          "ID" integer NOT NULL,
          "ACCOUNT_INFO" character varying(255),
          "CHARGE" character varying(255),
          "DELIVERY_INFO" character varying(255),
          "DESTINATION" character varying(255),
          "MESSAGE_ID" character varying(255),
          "RECEIPT_TYPE" integer,
          "SMS_CENTRE" character varying(255),
          "SMS_ID" character varying(255),
          "SOURCE" character varying(255),
          "STATUS" character varying(255),
          timedate date,
          "FLAG" character varying(255),
          "STID" character varying(255),
          CONSTRAINT "SMS_RECEIPT_pkey" PRIMARY KEY ("ID")
        );

          INSERT INTO SMS_RECEIPT_y2015m010 VALUES (NEW.*);
            ELSE
                RAISE EXCEPTION 'Date out of range.  Fix the measurement_insert_trigger() function!';
            END IF;
            RETURN NEW;
        END;
        $$
        LANGUAGE plpgsql;


        CREATE TRIGGER trigger_SMS_RECEIPT_insert
            BEFORE INSERT ON "SMS_RECEIPT"
            FOR EACH ROW EXECUTE PROCEDURE SMS_RECEIPT_func_insert_trigger();

现在我必须编写更新触发器函数，以便每当主表中有更新时，记录应相应地在分区中移动。

目前，当我在master表上编写update语句时，它会抛出错误：

ERROR:  new row for relation "sms_receipt_y2015m03" violates check constraint "sms_receipt_y2015m03_timedate_check"
DETAIL:  Failing row contains (2, asdf, asdf, asdf, asdf, asdf, 1234, asdfasd, asdfasdf, adsfad, adsfasd, 2015-04-22, adsf, were).
********** Error **********

ERROR: new row for relation "sms_receipt_y2015m03" violates check constraint "sms_receipt_y2015m03_timedate_check"
SQL state: 23514
Detail: Failing row contains (2, asdf, asdf, asdf, asdf, asdf, 1234, asdfasd, asdfasdf, adsfad, adsfasd, 2015-04-22, adsf, were).

所以，我在更新之前写了一个触发函数，如下所示：

Create or replace function sms_receipt_func_update_trigger()
returns trigger as $$
declare total integer;
begin
        IF exists( select 1 from SMS_RECEIPT_y2015m01 where "ID"=OLD."ID" and timedate = OLD.timedate ) THEN
                delete from SMS_RECEIPT_y2015m01 where "ID"=OLD."ID";

        ELSIF exists( select 1 from SMS_RECEIPT_y2015m02 where "ID"=OLD."ID" and timedate = OLD.timedate ) THEN
                delete from SMS_RECEIPT_y2015m02 where "ID"=OLD."ID";

    ELSIF exists( select 1 from SMS_RECEIPT_y2015m03 where "ID"=OLD."ID" and timedate = OLD.timedate ) THEN
                delete from SMS_RECEIPT_y2015m03 where "ID"=OLD."ID";
        ELSIF exists( select 1 from SMS_RECEIPT_y2015m04 where "ID"=OLD."ID" and timedate = OLD.timedate ) THEN
                delete from SMS_RECEIPT_y2015m04 where "ID"=OLD."ID";

    ELSIF exists( select 1 from SMS_RECEIPT_y2015m05 where "ID"=OLD."ID" and timedate = OLD.timedate ) THEN

        ELSIF exists( select 1 from SMS_RECEIPT_y2015m07 where "ID"=OLD."ID" and timedate = OLD.timedate ) THEN

    ELSIF exists( select 1 from SMS_RECEIPT_y2015m08 where "ID"=OLD."ID" and timedate = OLD.timedate ) THEN
                delete from SMS_RECEIPT_y2015m01 where "ID"=OLD."ID";

            ELSE
        RAISE EXCEPTION 'Date out of range.  Fix the measurement_insert_trigger() function!';
    END IF;
    RETURN NEW;
END;
$$
LANGUAGE plpgsql;


create trigger trigger_sms_receipt_update 
before update on "SMS_RECEIPT"
for each row execute procedure
sms_receipt_func_update_trigger();

但是，我仍然无法解决这个问题。有人可以告诉我如何修改更新触发器，以使这项工作。提前谢谢。

修改了这个，所以要使用视图而不是触发器。现在，它适用于插入方法。但是，如何处理Update事件？

Answer 1

问题是，使用触发器，您需要返回旧记录或新记录。

您需要而不是触发器。但它仅适用于视图。所以你需要：

创建一个视图（在主表上可以）
创建一个触发器＆＃34;而不是＆＃34;在视图上
更新并仅在视图上插入

请参阅此处的表格：http://www.postgresql.org/docs/9.4/static/sql-createtrigger.html

我测试了代码并发现了一些需要修复的东西。开始了。
首先，我插入一张记录进行测试：

INSERT INTO sms_receipt_view(
        "ID", "ACCOUNT_INFO", "CHARGE", "DELIVERY_INFO", "DESTINATION", 
        "MESSAGE_ID", "RECEIPT_TYPE", "SMS_CENTRE", "SMS_ID", "SOURCE", 
        "STATUS", timedate, "FLAG", "STID")
VALUES (1, 'acc_info', 'charge', 'delivery info', 'my dest', 
        'ssss id mess', 4, 'vodafone center', 'dff33', '3333 3 33333', 
        'ok', '20150601 15:25', 'myflag', 'stid');

其次，必须在插入时触发插入触发器，因此我运行代码：

DROP TRIGGER trigger_sms_receipt_insert ON sms_receipt_view;

CREATE TRIGGER trigger_sms_receipt_insert
  INSTEAD OF INSERT
  ON sms_receipt_view
  FOR EACH ROW
  EXECUTE PROCEDURE sms_receipt_func_insert_trigger();

然后我重写了更新触发器：

CREATE OR REPLACE FUNCTION sms_receipt_func_update_trigger()
  RETURNS trigger AS
$BODY$
begin
    --update "sms_receipt_view" set timedate = new.timedate where "ID"=new."ID";
    --check if I need to move record
    IF date_part('year', OLD.timedate) <> date_part('year', NEW.timedate) OR date_part('month', OLD.timedate) <> date_part('month', NEW.timedate) THEN
    DELETE FROM "SMS_RECEIPT" WHERE "ID" = NEW."ID";

    INSERT INTO sms_receipt_view ("ID", "ACCOUNT_INFO", "CHARGE", "DELIVERY_INFO", "DESTINATION", "MESSAGE_ID", "RECEIPT_TYPE",

首先，我检查一下是否真的需要移动记录。如果没有，我只需通过主表更新。如果我需要移动我删除旧记录并在视图中插入新记录（所以我触发插入视图）。
警告：在我的模拟中，我认为钥匙永远不会改变。如果您需要更新ID，则需要调整一些代码。

然后我测试了2个案例。在我的场景中，id为：1

UPDATE sms_receipt_view
SET "SMS_CENTRE" = 'tim center'
--timedate = '20150501'
WHERE "ID" = 1;

UPDATE sms_receipt_view
SET "SMS_CENTRE" = 'tim center',
timedate = '20150501'
WHERE "ID" = 1;

进行一些测试，但应该有效。

PostgreSQL：在主表上更新记录并在子分区中移动记录
