from tmp_tab_view A ,INS_USER F,INS_OFF_INS_USER T ,tmp_cust_info_tab_view v where A.USER_ID = F.USER_ID and F.USER_ID = T.USER_ID and A.USER_ID = v.user_id怎么转换成连彪

可以将上述 SQL 转换为以下联接查询：

SELECT *
FROM tmp_tab_view A
INNER JOIN INS_USER F ON A.USER_ID = F.USER_ID
INNER JOIN INS_OFF_INS_USER T ON F.USER_ID = T.USER_ID
INNER JOIN tmp_cust_info_tab_view v ON A.USER_ID = v.user_id;

这样可以更加简洁和易于理解。注意，这里使用了 INNER JOIN 进行联接，如果需要左联接或右联接，可以相应地进行修改。

select * from tmp_tab_view A inner join INS_USER F ON A.USER_ID = F.USER_ID inner join INS_OFF_INS_USER T ON F.USER_ID = T.USER_ID inner join tmp_cust_info_tab_view v ON A.USER_ID = v.user_id;可以优化一下嘛

这个查询语句可以进行以下优化：

1. 可以使用具体的字段代替 `SELECT *`，这样可以减少查询的数据量，提高查询效率。

2. 可以使用 WHERE 子句过滤数据，避免全表扫描。

3. 可以使用 EXISTS 或者 IN 子查询代替 JOIN 子句，因为 JOIN 子句在处理大数据量时会比较慢。

4. 可以创建索引来加快查询速度。

基于以上优化建议，可以尝试改写为以下语句：

SELECT A.col1, A.col2, F.col1, F.col2, T.col1, T.col2, v.col1, v.col2
FROM tmp_tab_view A, INS_USER F, INS_OFF_INS_USER T, tmp_cust_info_tab_view v
WHERE A.USER_ID = F.USER_ID 
AND F.USER_ID = T.USER_ID 
AND A.USER_ID = v.user_id 
AND v.col1 = 'some_value'

请将这个存储过程修改为触发器，当其余四个表插入新数据时，t_pcm_prod_own能够修改更新数据 CREATE DEFINER=root@% PROCEDURE test03() BEGIN -- 是否持有活期 IF EXISTS(SELECT CUST_ID FROM T_PCM_PROD_OWN WHERE CUST_ID IN (SELECT CUST_ID FROM T_PCM_DEP_CURR)) THEN UPDATE T_PCM_PROD_OWN SET IS_DEP = '1' WHERE CUST_ID IN (SELECT CUST_ID FROM T_PCM_DEP_CURR); ELSE UPDATE T_PCM_PROD_OWN SET IS_DEP = '0' WHERE CUST_ID IN (SELECT CUST_ID FROM T_PCM_DEP_CURR); END IF; -- 是否持有定期 IF EXISTS(SELECT CUST_ID FROM T_PCM_PROD_OWN WHERE CUST_ID IN (SELECT CUST_ID FROM T_PCM_DEP_FIXED)) THEN UPDATE T_PCM_PROD_OWN SET IS_FIXED_DEP = '1' WHERE CUST_ID IN (SELECT CUST_ID FROM T_PCM_DEP_FIXED); ELSE UPDATE T_PCM_PROD_OWN SET IS_FIXED_DEP = '0' WHERE CUST_ID IN (SELECT CUST_ID FROM T_PCM_DEP_FIXED); END IF; -- 是否持有贷款 IF EXISTS(SELECT CUST_ID FROM T_PCM_PROD_OWN WHERE CUST_ID IN (SELECT CUST_ID FROM T_PCM_LOAN)) THEN UPDATE T_PCM_PROD_OWN SET IS_LOAN = '1' WHERE CUST_ID IN (SELECT CUST_ID FROM T_PCM_LOAN); ELSE UPDATE T_PCM_PROD_OWN SET IS_LOAN = '0' WHERE CUST_ID IN (SELECT CUST_ID FROM T_PCM_LOAN); END IF; -- 是否持有理财 IF EXISTS(SELECT CUST_ID FROM T_PCM_PROD_OWN WHERE CUST_ID IN (SELECT CUST_ID FROM T_PCM_WEALTH)) THEN UPDATE T_PCM_PROD_OWN SET IS_WEALTH = '1' WHERE CUST_ID IN (SELECT CUST_ID FROM T_PCM_WEALTH); ELSE UPDATE T_PCM_PROD_OWN SET IS_WEALTH = '0' WHERE CUST_ID IN (SELECT CUST_ID FROM T_PCM_WEALTH); END IF; INSERT INTO T_PCM_PROD_OWN SELECT REPLACE(UUID(),'-','') ,T_PCM_CUST.CUST_ID ,T_PCM_CUST.LAW_ORG_ID ,T_PCM_CUST.ECIF_CUST_ID ,T_PCM_PROD_OWN.IS_DEP ,T_PCM_PROD_OWN.IS_FIXED_DEP ,T_PCM_PROD_OWN.IS_LOAN ,T_PCM_PROD_OWN.IS_WEALTH ,T_PCM_DEP_CURR.CURRENT_BAL ,T_PCM_DEP_FIXED.BAL ,T_PCM_LOAN.LOAN_MON ,T_PCM_WEALTH.CURRENT_BAL FROM T_PCM_CUST LEFT JOIN T_PCM_DEP_CURR ON T_PCM_CUST.CUST_ID = T_PCM_DEP_CURR.CUST_ID LEFT JOIN T_PCM_DEP_FIXED ON T_PCM_CUST.CUST_ID = T_PCM_DEP_FIXED.CUST_ID LEFT JOIN T_PCM_LOAN ON T_PCM_CUST.CUST_ID = T_PCM_LOAN.CUST_ID LEFT JOIN T_PCM_WEALTH ON T_PCM_CUST.CUST_ID = T_PCM_WEALTH.CUST_ID LEFT JOIN T_PCM_PROD_OWN ON T_PCM_CUST.CUST_ID = T_PCM_PROD_OWN.CUST_ID; END

您好！根据您的要求，将存储过程修改为触发器，当其余四个表插入新数据时，t_pcm_prod_own将能够修改更新数据。以下是修改后的触发器代码：

CREATE DEFINER=root@% TRIGGER trg_test03
AFTER INSERT ON T_PCM_DEP_CURR
FOR EACH ROW
BEGIN
  -- 是否持有活期
  IF EXISTS(SELECT CUST_ID FROM T_PCM_PROD_OWN WHERE CUST_ID = NEW.CUST_ID) THEN
    UPDATE T_PCM_PROD_OWN
    SET IS_DEP = '1'
    WHERE CUST_ID = NEW.CUST_ID;
  ELSE 
    UPDATE T_PCM_PROD_OWN
    SET IS_DEP = '0'
    WHERE CUST_ID = NEW.CUST_ID;
  END IF;
END;

CREATE DEFINER=root@% TRIGGER trg_test03_2
AFTER INSERT ON T_PCM_DEP_FIXED
FOR EACH ROW
BEGIN
  -- 是否持有定期
  IF EXISTS(SELECT CUST_ID FROM T_PCM_PROD_OWN WHERE CUST_ID = NEW.CUST_ID) THEN
    UPDATE T_PCM_PROD_OWN
    SET IS_FIXED_DEP = '1'
    WHERE CUST_ID = NEW.CUST_ID;
  ELSE 
    UPDATE T_PCM_PROD_OWN
    SET IS_FIXED_DEP = '0'
    WHERE CUST_ID = NEW.CUST_ID;
  END IF;
END;

CREATE DEFINER=root@% TRIGGER trg_test03_3
AFTER INSERT ON T_PCM_LOAN
FOR EACH ROW
BEGIN
  -- 是否持有贷款
  IF EXISTS(SELECT CUST_ID FROM T_PCM_PROD_OWN WHERE CUST_ID = NEW.CUST_ID) THEN
    UPDATE T_PCM_PROD_OWN
    SET IS_LOAN = '1'
    WHERE CUST_ID = NEW.CUST_ID;
  ELSE 
    UPDATE T_PCM_PROD_OWN
    SET IS_LOAN = '0'
    WHERE CUST_ID = NEW.CUST_ID;
  END IF;
END;

CREATE DEFINER=root@% TRIGGER trg_test03_4
AFTER INSERT ON T_PCM_WEALTH
FOR EACH ROW
BEGIN
  -- 是否持有理财
  IF EXISTS(SELECT CUST_ID FROM T_PCM_PROD_OWN WHERE CUST_ID = NEW.CUST_ID) THEN
    UPDATE T_PCM_PROD_OWN
    SET IS_WEALTH = '1'
    WHERE CUST_ID = NEW.CUST_ID;
  ELSE 
    UPDATE T_PCM_PROD_OWN
    SET IS_WEALTH = '0'
    WHERE CUST_ID = NEW.CUST_ID;
  END IF;
END;

请注意，每个表都有一个单独的触发器，以确保在插入新数据时更新相应的列。触发器将根据新插入的数据的CUST_ID值来更新t_pcm_prod_own表中的相关列。
