我正在寻找没有Spring数据的解决方案。我的项目要求是不使用spring数据。通过mongo命令使用聚合函数计算总和，能够得到输出。但同样通过使用spring数据获取异常。示例mongo查询:db.getCollection('events_collection').aggregate({"$match":{"store_no":3201,"event_id":882800}},{"$group":{"_id":"$load_dt","event_id":{"$first":"$event_id"},"start_dt":{"$first":"$start_dt"},"count":
我在获取所有帐户的余额时遇到了一些问题。所有账户在存款收集中都引用了不同的存款项目。帐户收集:[{"_id":"56b1ce63315748b44f1174e1","name":"Foobar","deposits":[{"$oid":"56b1ce78315748b44f1174e2"}]}]存款收集:{"_id":{"$oid":"56b1deb84f40bfa435e22f3f"},"account":{"$oid":"56b1dea34f40bfa435e22f3e"},"amount":300,"date":{"$date":"2016-02-01T00:00:00.000Z
我正致力于在MongoDB中开发一个管道，它将每个州的公司的所有number_of_employees相加，并打印出每个州的信息。集合结构的基本原理如下所示:"name":"AdventNet","number_of_employees":600,"offices":[{"description":"Headquarters","address1":"4900HopyardRd.","address2":"Suite310","zip_code":"94588","city":"Pleasanton","state_code":"CA","country_code":"USA","la
集合中的示例文档{"_id":2,"student":"Ryan","homework":[5,6,5],"quiz":[8,8],"extraCredit":8}mongodb中的聚合查询db.scores.aggregate([{$project:{_id:"$_id",hSum:{$sum:"$homework"},qSum:{$sum:"$quiz"},}}])上述聚合查询的输出{"_id":2,"hSum":16,"qSum":16}我想将上述mongo查询转换为spring-data格式。我想在spring数据中使用projectionOperations进行聚合。proj
我想从mongodb文档中计算员工积分。我在员工积分收藏中的文件如下[{"EmployeeID":"Cust0001","Point":1,},{"EmployeeID":"Cust0002","Point":2,},{"EmployeeID":"Cust0003","Point":1,},{"EmployeeID":"Cust0001","Point":5,},{"EmployeeID":"Cust0001","Point":2,}]预期结果[{"EmployeeID":"Cust0001","Total_Points":8},{"EmployeeID":"Cust0002","To
我正在尝试总数notnull范围total我的AngularJS对象中的字段，然后我想计算百分比。例如：在我的对象中包含10个字段。两个字段有一些值（其他字段null).Completed=(notnullfields/totalfields)*100=(4/11)*100=36.36%我的控制器myApp.controller('PController',function($scope,localStorageService){$scope.user=localStorageService.get("user");console.log(Object.keys($scope.user).le
在MongoDB上我有一个这样的集合:-{org:"org",departments:[{name:"abc",employees:[{name:"number1"},{name:"number2"},{name:"number3"},]},{name:"mno",employees:[{name:"number4"},{name:"number5"}]},{name:"xyz",employees:[{name:"number6"},{name:"number7"}]}]},{org:"xyz"....}如何使用聚合查找“org”中的员工总数？期待结果{组织:“组织”，员工总数:7}
我找不到这方面的任何例子，所以我不确定这是否可行。我有以下文件db.mytest.insert([{date:newDate('2013-06-01'),account:'A',ids:[{id:'1vb',sale:50},{id:'xy2',sales:25}]},{date:newDate('2013-06-02'),account:'A',ids:[{id:'1vb',sales:10},{id:'xy2',sales:5}]}])我正在尝试获得以下结果[{account:'A':ids:[{id:'1vb',salesAmount:60,salesCount:8},{id:'

我有两张纸，叫做BW，表2称为原因。在表1中，我有列广告直到AW，必须单独添加。我在Sheep2中有表格，其中列出了AD的列名，直到AW。在第2页的第二列中，我需要AD列的总和直至AW。我尝试了下面的代码Subsum()DimBWlRowAsLong,CWlRowAsLong,iAsLongDimSformulaAsStringDimwsBWAsWorksheet,wsCWAsWorksheetSetwsBW=Sheets("BW"):SetwsCW=Sheets("Reasons")BWlRow=wsBW.Cells(wsBW.Rows.Count,"A").End(xlUp).RowCWl
