Question

我有一个带列的模型：

from: { type: Sequelize.DATE }
to: { type: Sequelize.DATE }

并希望查询from或to落在日期范围之间的所有记录：[startDate, endDate]

我尝试过类似的事情：

＆＃13;

const where = {
      $or: [{
        from: {
          $lte: startDate,
          $gte: endDate,
        },
        to: {
          $lte: startDate,
          $gte: endDate,
        },
      }],
    };

＆＃13;

像： SELECT *来自MyTable WHERE（startDate＆lt; = from＆lt; = endDate）OR（startDate＆lt; = to＆lt; = endDate

Answer 1

对我有用的解决方案是： -

# here startDate and endDate are Javascript Date object
const where = {
    from: {
        $between: [startDate, endDate]
    }
};

注意：在 MYSQL between比较运算符包含，这意味着它等同于表达式(startDate <= from AND from <= endDate)。

Answer 2

尝试这种情况，我想你会问的。

用于Sequelize的新版本：

      -a     Each name is an indexed array variable (see Arrays above).
      -A     Each name is an **associative** array variable (see Arrays above).

或作为您的代码结构：

const where = {
    [Op.or]: [{
        from: {
            [Op.between]: [startDate, endDate]
        }
    }, {
        to: {
            [Op.between]: [startDate, endDate]
        }
    }]
};
