Question

我想在属性中运行一个函数，并使startDate和endDate之间有所不同。但是当我执行代码时，出现以下错误：

列“ Signals.id”必须出现在GROUP BY子句中或用于聚合函数

const lastData = await psql.Signals.findAll({
    attributes: [
     "id",
     "strategy",
     "type",
     "symbol",
     "name",
     "timeframe",
     "status",
     "startDate",
     "endDate",
     [
      Sequelize.literal('EXTRACT(DAY FROM MAX("startDate")-MIN("endDate"))'),
      "DateDifference"
     ],
     "positionsData"
    ],
    where: {
     isMain: true,
     strategy: {
      [Op.in]: ["21", "22"]
     }
    },
    order: [["id", "DESC"]],
    limit: 50,
    raw: true
   })

Sequelizejs预期的SQL代码是：

SELECT "id", "strategy", "type", "symbol", "name", "timeframe", "status", "startDate", "endDate", EXTRACT(DAY FROM MAX("startDate")-MIN("endDate")) AS "DateDifference", "positionsData" FROM "signals" AS "Signals" WHERE "Signals"."isMain" = true AND "Signals"."strategy" IN ('21', '22') ORDER BY "Signals"."id" DESC LIMIT 50;

有人可以帮助我吗？怎么了？！

摘要函数（MIN，MAX，SUM等）通常需要GROUP BY子句。 MIN和MAX日期字段应应用于什么数据集？每个ID是否会有多个日期？

在列上运行函数的Sequelizejs错误-in中的check_ungrouped_columns_walker
