String sql = "select * from foodrecord a join foodcalory b on a.foodname = b.foodname where DATE_FORMAT(date,'%Y-%m-%d') = CURDATE() and phone='"+phone+"';";什么意思

这段代码是一个 SQL 语句，它的作用是查询今天某个电话号码对应的所有食品记录及其对应的卡路里信息。具体来说，它使用了两张表 foodrecord 和 foodcalory，通过 foodname 字段进行连接（join）。然后，它使用了 MySQL 中的 DATE_FORMAT 函数，将日期格式化为 '%Y-%m-%d' 的形式，并与 CURDATE() 进行比较，以查询今天的数据。最后，它使用了一个变量 phone，用于替换 SQL 语句中的字符串，以便查询指定电话号码的数据。

这个SQL查询语句存在几个错误：

1. 在第一个子查询中，你将别名为'originalOrderType'的列用作WHERE子句中的条件，但是在WHERE子句之前，你并没有选择这个别名列。你需要在SELECT子句中选择这个别名列，并将其作为WHERE子句的条件之一。

2. 在第二个子查询中，你使用了一个不存在的列名'source_of_delivery_note'作为OR条件的一部分。你需要确保这个列名是正确的。

3. 在整个查询中，你使用了一些字符串常量，如'string'和'2023-07-07 00:00:00.0'。请确保这些字符串常量的格式正确，并且在查询中使用正确的语法。

请修复这些错误并重新运行查询。

您的SQL语句中存在一处不合法的地方，即在最外层的FROM子句之后没有指定要查询的表名或子查询。您需要将要查询的表名或子查询添加到FROM子句中，例如：

SELECT  
    create_date,
    major_biz_name,
    minor_biz_name,
    minimal_biz_name,
    call_type,
    service_line,
    finance_type,
    min_cnt,
    finance_user_cnt
FROM (
    SELECT
        '${zdt.addDay(-1).format("yyyy-MM")}' AS create_date,
        major_biz_name,
        minor_biz_name,
        minimal_biz_name,
        call_type,
        service_line,
        finance_type,
        COUNT(1) AS min_cnt
    FROM dm_pay.finance_call_in_cnt_di
    WHERE SUBSTR(CAST(day AS STRING), 1, 6) = '${zdt.addDay(-1).format("yyyyMM")}'
    GROUP BY
        major_biz_name,
        minor_biz_name,
        minimal_biz_name,
        call_type,
        service_line,
        finance_type
) a
LEFT JOIN (
    SELECT MAX(user_cnt) AS finance_user_cnt
    FROM dm_njbi.active_user_30days_finance_di
    WHERE day = ${zdt.addDay(-1).format("yyyyMMdd")}
) b ON 1=1;

请将您要查询的表名或子查询添加到相应位置后重新执行查询。
