如何在我的结果集中获取数字

Question

我有一个模型设置，并且正在执行带有一些分组和不同计数的SQL查询。然而，sequelize将这些计数作为字符串返回。如何将其作为数字返回，或者我将不得不手动转换结果集？

 report_table.findAll({
        attributes: [
            [report_table.sequelize.fn("concat", report_table.sequelize.col("application"), report_table.sequelize.col("document_title")), "_id"],
            "application", "document_title",  [report_table.sequelize.fn('count', report_table.sequelize.col('view_id')), "view count"],
            [report_table.sequelize.fn('count', report_table.sequelize.fn('DISTINCT', report_table.sequelize.col('client_id'))), "user count"],
            [report_table.sequelize.fn('max', report_table.sequelize.col('date')), "last view"]
        ],
        where: {
            tag_type: "event",
            application: {
                $in: applications
            }
        },
        group: ["application", "document_title"],
        order: [
            [report_table.sequelize.fn('count', report_table.sequelize.col('view_id')), "DESC"]
        ]
    }).then(callback);
