使用已定义函数的 UPDATE 语句的排序规则错误

Question

正如您将从我的代码中看到的那样，我已经指定了我创建的 table 和函数的 return 的排序规则，但我仍然收到错误消息。这是为什么？

我在 PHPmyAdmin-MYSQL 中应用查询时收到以下错误： SQL查询： UPDATE tb SET balance = (SELECT fnaccount_getbalance(acguid COLLATE utf8_general_ci,accur COLLATE utf8_general_ci,@stdate,@endate)) 错误：

1267 - 操作 '='

的排序规则 (utf8_unicode_ci,IMPLICIT) 和 (utf8_general_ci,IMPLICIT) 的非法混合

这是我的查询：

CREATE TEMPORARY TABLE tb (id INT PRIMARY KEY AUTO_INCREMENT,
                           acguid char(38),
                           accur char(38),
                           account varchar(255),
                           debitsyp float,
                           creditsyp float,
                           balance float,
                           currency varchar(255))
CHARACTER SET utf8
COLLATE utf8_unicode_ci;
SET @stdate = '2011-01-01';
SET @endate = CURDATE();

INSERT INTO tb (acguid,accur,account,debitsyp,creditsyp,balance,currency)
SELECT ac.guid,ac.currencyguid,CONCAT(ac.code,'-',ac.name) AS account,0,0,0,my.code
FROM ac000 ac INNER JOIN my000 my ON ac.currencyguid = my.guid
WHERE ac.guid IN (SELECT accountguid FROM en000);

UPDATE tb SET debitsyp = (SELECT SUM(debit) FROM en000 WHERE accountguid = acguid);
UPDATE tb SET creditsyp = (SELECT SUM(credit) FROM en000 WHERE accountguid = acguid);

UPDATE tb SET balance  = (SELECT fnaccount_getbalance(acguid,accur,@stdate,@endate));

SELECT * FROM tb;

这是我的函数的代码 fnaccount_getbalance:

BEGIN
    DECLARE acbal float;
    SET acbal = (SELECT IFNULL(SUM((CASE
                                    WHEN currencyguid = accur THEN debit / currencyval
                                    ELSE debit / fngetcurval(accur,endate)
                                    END) - 
                                (CASE
                                    WHEN currencyguid = accur THEN credit / currencyval
                                    ELSE credit / fngetcurval(accur,endate)
                                END)),0) as balance
                FROM en000 WHERE accountguid = acguid
                AND endate BETWEEN stdate AND endate);
    
    RETURN (acbal COLLATE utf8_unicode_ci);
END

我通过将数据库排序规则更改为 utf8_unicode_ci

解决了这个问题

之前是utf8_general_ci

然后我删除并重新创建了我在新 SQL 查询中拥有的所有功能

最初我根据另一个网站的建议将数据库排序规则设置为 utf8_general_ci，将 DATABASE 排序规则设置为 unicode 而不是一般的排序规则不好吗？
