Sequelize抱怨＆＃34;滥用聚合：SUM（）＆＃34;在原始查询中使用双引号和单引号时

标签： sql node.js sqlite sequelize.js

当我在DB Browser for SQLite中运行此查询时：

SELECT week
, SUM (CASE when activityType = 'rockclimbing' then elapsedTime else 0 END) AS rockclimbing
, SUM (CASE when activityType = 'hike' then elapsedTime else 0 END) AS hike
, SUM (CASE when activityType = 'run' then elapsedTime else 0 END) AS run
FROM activity
WHERE year=2016
AND activityType IN ('rockclimbing', 'hike', 'run')
GROUP BY week
ORDER BY week;

它返回我要查找的数据：

week rockclimbing hike run

"1" "0" "0" "2.09"

"2" "0" "0" "4.63"

"3" "0" "0" "7.22"

"4" "0" "0" "2.94"

"5" "0" "0" "5.59"

（忽略＆＃34;引号＆＃34;。随后复制/粘贴包含它们的数据。）

然而，当我使用.query（）将此查询传递给Sequelize时，我收到错误：misuse of aggregate: SUM()

这是我的Sequelize代码：

sequelize.query('SELECT week, SUM (CASE when activityType = "rockclimbing" then elapsedTime else 0 END) AS rockclimbing, SUM (CASE when activityType = "hike" then elapsedTime else 0 END) AS hike, SUM (CASE when activityType = "run" then elapsedTime else 0 END) AS run FROM activity WHERE year=2016 AND activityType IN ("rockclimbing", "hike", "run") GROUP BY week ORDER BY week;', { model: Activity }).then(...etc..).catch(...etc...);

以下是Sequelize生成的查询并在我的控制台中输出：

Executing (default): SELECT week, SUM (CASE when activityType = "rockclimbing" then elapsedTime else 0 END) AS rockclimbing, SUM (CASE when activityType = "hike" then elapsedTime else 0 END) AS hike, SUM (CASE when activityType = "run" then elapsedTime else 0 END) AS run FROM activity WHERE year=2016 AND activityType IN ("rockclimbing", "hike", "run") GROUP BY week ORDER BY week;

我的JavaScript .catch()错误并将其记录到控制台：

.catch(function(err) {
  console.log('Error! ', err);
});

所以我看到这个错误对象已经注销到我的控制台：

这是什么问题？为什么此查询在数据库浏览器中有效但在我的应用程序中无效？

我在发布此问题之前搜索了Internet和Stackoverflow。虽然some questions did touch on my issue当我尝试时没有任何建议/解决方案帮助我/工作。

这里有一些细微差别，其中一个很重要：我在javascript中转换了'和"个字符。

> Executing (default): SELECT * FROM `activity`
[ { activityType: 'rockclimbing',
    year: 2017,
    week: 1,
    elapsedTime: 1.2345 },
  { activityType: 'rockclimbing',
    year: 2017,
    week: 2,
    elapsedTime: 1.2345 },
  { activityType: 'rockclimbing',
    year: 2017,
    week: 3,
    elapsedTime: 66.45 },
  { activityType: 'hike', year: 2017, week: 1, elapsedTime: 1.2345 },
  { activityType: 'hike',
    year: 2017,
    week: 2,
    elapsedTime: 3.141592 },
  { activityType: 'hike', year: 2017, week: 3, elapsedTime: -1 },
  { activityType: 'hike', year: 2017, week: 4, elapsedTime: 10000 },
  { activityType: 'run', year: 2017, week: 4, elapsedTime: 10 },
  { activityType: 'run', year: 2017, week: 5, elapsedTime: 100 },
  { activityType: 'run', year: 2017, week: 6, elapsedTime: 1000 } ]

> sequelize.query("SELECT week, SUM (CASE when activityType = 'rockclimbing' then elapsedTime else 0 END) AS rockclimbing, SUM (CASE when activityType = 'hike' then elapsedTime else 0 END) AS hike, SUM (CASE when activityType = 'run' then elapsedTime else 0 END) AS run FROM activity     WHERE year=2017 AND activityType IN ('rockclimbing', 'hike', 'run') GROUP BY week ORDER BY week", { type: sequelize.QueryTypes.SELECT}).then(function(activities) {console.log(activities)})
Promise {
  _bitField: 0,
  _fulfillmentHandler0: undefined,

结果：

[ { week: 1, rockclimbing: 1.2345, hike: 1.2345, run: 0 },
  { week: 2, rockclimbing: 1.2345, hike: 3.141592, run: 0 },
  { week: 3, rockclimbing: 66.45, hike: -1, run: 0 },
  { week: 4, rockclimbing: 0, hike: 10000, run: 10 },
  { week: 5, rockclimbing: 0, hike: 0, run: 100 },
  { week: 6, rockclimbing: 0, hike: 0, run: 1000 } ]

DDL＆amp; DML：

sqlite> create table activity ( activityType varchar(20), year int, week int, elapsedTime float);
sqlite> insert into activity values ('rockclimbing',2017,1,1.2345);
sqlite> insert into activity values ('rockclimbing',2017,2,1.2345);
sqlite> insert into activity values ('rockclimbing',2017,3,66.45);
sqlite> insert into activity values ('hike',2017,1,1.2345);
sqlite> insert into activity values ('hike',2017,2,3.141592);
sqlite> insert into activity values ('hike',2017,3,-1);
sqlite> insert into activity values ('hike',2017,4,10000);
sqlite> insert into activity values ('run',2017,4,10);
sqlite> insert into activity values ('run',2017,5,100);
sqlite> insert into activity values ('run',2017,6,1000);

SQLite期待单引号，并且似乎抛出了错误的错误。
