用于聚合一个表的MySQL触发器'；将行移动到另一个表

我有两张MySQL表， 将使用需要聚合的新行进行更新的行（表1）。 还有一个应该使用mysql触发器自动填充聚合数据（表2）

给定表架构：

表1的示例： 要聚合的表

唯一键

uniqueid

（

uniqueid

，

ci

，

ai

，

状态

）

表2的示例： 聚合表

唯一键

IX\u UNIQUE\u daily

（

ai

，

ci

，

day

）

SQL触发器应该类似于：

创造 触发器

yii_botclient2

st_unqiue_触发器插入后
在
yii_botclient2
st_unique
每行开始

SET @myDay := DATE(NEW.date);
SET @today = DATE();
SET isDaily := SELECT COUNT(id) FROM `yii_botclient2`.`st_daily` WHERE `ai` = NEW.ai AND st_daily.ci = NEW.ci AND st_daily.day = @myDay;
SET myDaily = IFNULL(isDaily, 'No');

IF (myDaily = 'No') THEN
    IF NEW.status = 0
        INSERT INTO st_daily (`day`, `ai`,`ci`,`impressions`,`updated`) VALUES (@today,NEW.ai,NEW.ci,1,NOW());
    ELSEIF NEW.status = 1 
        INSERT INTO st_daily (`day`, `ai`,`ci`,`clicks`,`updated`) VALUES (@today,NEW.ai,NEW.ci,1,NOW());
    ELSEIF NEW.status = 2
        INSERT INTO st_daily (`day`, `ai`,`ci`,`leads`,`updated`) VALUES (@today,NEW.ai,NEW.ci,1,NOW());
    ELSEIF NEW.status = 3 
        INSERT INTO st_daily (`day`, `ai`,`ci`,`ftds`,`updated`) VALUES (@today,NEW.ai,NEW.ci,1,NOW());
    END IF;
ELSE
    IF NEW.status = 0
        UPDATE st_daily SET `impressions` = `impressions` + 1 WHERE st_daily.ci = NEW.ci AND st_daily.ai = NEW.ai AND st_daily.day = @myDay;
    ELSEIF NEW.status = 1 
        UPDATE st_daily SET `clicks` = `clicks` + 1 WHERE st_daily.ci = NEW.ci AND st_daily.ai = NEW.ai AND st_daily.day = @myDay;
    ELSEIF NEW.status = 2
        UPDATE st_daily SET `leads` = `leads` + 1 WHERE st_daily.ci = NEW.ci AND st_daily.ai = NEW.ai AND st_daily.day = @myDay;
    ELSEIF NEW.status = 3 
        UPDATE st_daily SET `ftds` = `ftds` + 1 WHERE st_daily.ci = NEW.ci AND st_daily.ai = NEW.ai AND st_daily.day = @myDay;
    END IF;
END IF;
