Question

我在电子表格中有一个google脚本，可以从日历中加载约会。它计算约会的时间。但是要更新日历项需要很长时间，我经常会遇到超时错误。从日历中获取约会不是问题。在脚本下提到的电子表格的每10个选项卡中的查询是否会降低速度？

function updateUren()
{

  var cal = CalendarApp.openByName("Uren");
  var sheet = SpreadsheetApp.getActiveSpreadsheet().getSheetByName("Uren");

  //set first row
  var details=[["title", "date", "start", "end", "duration"]]; // events[i].getDescription(),
  var range=sheet.getRange(2,1,1,5);
  range.setValues(details);

  //gets the year from Boekjaar
  var year = SpreadsheetApp.getActiveSpreadsheet().getSheetByName("Boekjaar").getRange(2,1,1,1).getValue();

  var events = cal.getEvents(new Date("January 1, "+year), new Date("December 31, "+year));
  if(events.length == 0)
  {
    Browser.msgBox('No events found for year: "' + year + '"');
  }
  for (var i=0;i<events.length;i++) {
    //http://www.google.com/google-d-s/scripts/class_calendarevent.html
    var startTime = events[i].getStartTime();
    var endTime = events[i].getEndTime();
    var durationHours = (endTime - startTime) / (1000*60*60);
    var details=[[events[i].getTitle(), startTime, startTime, endTime, durationHours]]; // events[i].getDescription(),
    var row=i+3;
    range=sheet.getRange(row,1,1,5);
    range.setValues(details);
  }
  var foo = "foo";
}

我有10个选项卡正在运行我在此处显示的查询。他们过滤特定时期的约会持续时间

=QUERY (Uren!A:E, "SELECT B, SUM(E) WHERE A CONTAINS 'SomeKeyWord' AND B>=DATETIME '2012-6-18 00:00:00'
AND B<DATETIME '2012-7-16 00:00:00' GROUP BY B PIVOT A'")

在调用updateUren（）函数期间，它们是否昂贵且减慢了速度？

有人知道答案吗？

我不确定访问数据的QUERY函数是否与它有关（它可能），但我的理解是最好不要在循环中进行获取/设置，因为这会大大减慢速度。相反，首先构建您的数组，然后使用一个setValues（）调用来设置它。

function updateUren()
{

  var cal = CalendarApp.openByName("Uren");
  var sheet = SpreadsheetApp.getActiveSpreadsheet().getSheetByName("Uren");

  //create first row of 2D array
  var details=[["title", "date", "start", "end", "duration"]]; // events[i].getDescription(),

  //gets the year from Boekjaar
  var year = SpreadsheetApp.getActiveSpreadsheet().getSheetByName("Boekjaar").getRange(2,1,1,1).getValue();

  var events = cal.getEvents(new Date("January 1, "+year), new Date("December 31, "+year));
  if(events.length == 0)
  {
    Browser.msgBox('No events found for year: "' + year + '"');
  }

  for (var i=0;i<events.length;i++) {
    //http://www.google.com/google-d-s/scripts/class_calendarevent.html
    var startTime = events[i].getStartTime();
    var endTime = events[i].getEndTime();
    var durationHours = (endTime - startTime) / (1000*60*60);
    details.push([events[i].getTitle(), startTime, startTime, endTime, durationHours]); // events[i].getDescription(),
  }
  sheet.getRange(2, 1, details.length, 5).setValues(details);
  //var foo = "foo";
}

编辑：虽然您仍然在循环内调用Calendar服务。我应该补充说这是未经测试的，但有兴趣听听它是否有所作为。
