Nested aggregate functions

Functions can contain functions, so it’s possible to pass the result of one aggregate function to another aggregate function for compound operations. For example, with regards to a sale amount, first weigh the amount and then converted to a specific currency using: CurrencyConvert(Weighted(amount;probPercent);currencyId))

Scenario 1

To demonstrate the concept, construct a query that displays the top sales representatives this month. Do this by specifying a restriction where the userGroup equals the sales group, the saleStatus is sold, and the sale date is within the past month. Sort the results by the sum of the sale amount, descending. Then add the following aggregate functions to display the results in a footer - one for each distinct group:

using Sum and ConvertCurrency, convert all sale amounts to one currency and then sum the amounts.
use GroupBy to divide the results by full name, personId, and title.

// get a currencyId to convert sale amount to.
var currency = SuperOffice.CRM.Rows.Util.CurrencyConversionHelper.BaseCurrencyId;

// set the formatted function for use in multiple places below
var formattedSum = string.Format("Sum(CurrencyConvert(amount;{0})):HideDetail", currency);

// use selection provider to get all my completed activities this month
var provider = ArchiveProviderFactory.Create("saledynamicselection");
provider.SetDesiredEntities("sale");
provider.SetPagingInfo(100, 0);

// specify the sort order
provider.SetOrderBy( new ArchiveOrderByInfo( formattedSum, SuperOffice.Data.OrderBySortType.DESC));

// Set the aggregate functions to get how many of each, grouped by type
provider.SetDesiredColumns(
  formattedSum,
  "GroupBy(associate/fullName):Footer,HideDetail", //default level 1, no nesting
  "GroupBy(associate/personId):Footer,HideDetail", //default level 1, no nesting
  "GroupBy(associate/title):Footer,HideDetail"     //default level 1, no nesting
  );

// specify the restrictions
provider.SetRestriction(
  new ArchiveRestrictionInfo("userGroup", "oneOf", SuperOffice.SoContext.CurrentPrincipal.GroupId),
  new ArchiveRestrictionInfo("saleStatus", "oneOf", "2"),
  new ArchiveRestrictionInfo("date", ">", CultureDataFormatter.EncodeDate(DateTime.Now.AddMonths(-1))),
  new ArchiveRestrictionInfo("selectionId", "=", "-1")
  );

foreach (var row in provider.GetRows(AggregationProvider2.GrandTotalOption + "=True"))
{
  if(row.RowType.StartsWith("footer"))
  {
    var fullName = row.ColumnData["GroupBy(associate/fullName):Footer,HideDetail"].DisplayValue;
    var personId = row.ColumnData["GroupBy(associate/personId):Footer,HideDetail"].DisplayValue;
    var perTitle = row.ColumnData["GroupBy(associate/title):Footer,HideDetail"].DisplayValue;
    var persoSum = row.ColumnData[formattedSum].DisplayValue;
    Console.WriteLine("Fullname: {0}, PersonId: {1}, Title: {2}, Sum: {3}",
      fullName, personId, perTitle, CultureDataFormatter.LocalizeEncoded(persoSum));
  }
  else if(row.RowType.StartsWith("grandtotal"))
  {
    var grandTotalSum = row.ColumnData[formattedSum].DisplayValue;
    Console.WriteLine("Grand Total: {0}", CultureDataFormatter.LocalizeEncoded(grandTotalSum));
  }
}

The CultureDataFormatter method is used to format the summed amount into local currency in both the footer and grandtotal rows.

Query results

Rowno	Row type	GroupBy (associate/fullName): Footer,HideDetail	GroupBy (associate/personId): Footer,HideDetail	GroupBy (associate/title): Footer,HideDetail	Sum (CurrencyConvert (amount;36)): HideDetail
0 (1)	[footer:1]	Rebecca Franklin	9	Sales Representative	1 480 110,00
1 (2)	[footer:1]	Sean Baker	8	Tech and Sales	152 495,00
2 (1)	[grandtotal]				1 632 605,00

Scenario 2

Another common scenario to demonstrate nested functions is to group sales based on a DatePart. Combined with a GroupBy, the use of DatePart makes it easy to aggregate sales by week, month, or quarter. Use the previous example as a template and modify the restriction sale date to show just this year. Modify the Sort to use the GroupBy DatePart, ascending. Then change the desired columns to just include the Sum of sale amounts and a GroupBy to divide the results by months.

var currency = SuperOffice.CRM.Rows.Util.CurrencyConversionHelper.BaseCurrencyId;

// set the formatted function for use in multiple places below
var formattedSum = string.Format("Sum(CurrencyConvert(amount;{0})):HideDetail", currency);

// use selection provider to get all my completed activities this month
var provider = ArchiveProviderFactory.Create("saledynamicselection");

// Set the aggregate functions to get how many sales, grouped by Month
provider.SetDesiredColumns(formattedSum, "GroupBy(DatePart(date):Month):Footer,HideDetail");
provider.SetDesiredEntities("sale");
provider.SetPagingInfo(100, 0);

// specify the restrictions
provider.SetRestriction(
  new ArchiveRestrictionInfo("userGroup", "oneOf", SuperOffice.SoContext.CurrentPrincipal.GroupId),
  new ArchiveRestrictionInfo("saleStatus", "oneOf", "2"),
  new ArchiveRestrictionInfo("date", "thisYear"),
  new ArchiveRestrictionInfo("selectionId", "=", "-1")
  );

// set the sort by to the month ascending
provider.SetOrderBy(
  new ArchiveOrderByInfo("GroupBy(DatePart(date):Month):Footer,HideDetail",
  SuperOffice.Data.OrderBySortType.ASC)
);

using (ArchiveRowDumper d = new ArchiveRowDumper(provider))
{
  foreach (var row in provider.GetRows(AggregationProvider2.GrandTotalOption + "=True"))
  {
    if (row.RowType.StartsWith("footer"))
    {
      // get the month and sale sum data
      var monthInt = (int)row.ColumnData["GroupBy(DatePart(date):Month):Footer,HideDetail"].RawValue;
      var foSum = row.ColumnData[formattedSum].DisplayValue;

      // convert the integer representation of month to month name
      var monthName = System.Globalization.CultureInfo.CurrentCulture.DateTimeFormat.GetMonthName(monthInt);
      Debug.WriteLine("Month: {0}, Sum: {1}", monthName, foSum);
    }
    else if (row.RowType.StartsWith("grandtotal"))
    {
      // get out the total sum value
      var grandTotalSum = row.ColumnData[formattedSum].DisplayValue;
      Debug.WriteLine("Grand Total: {0}", CultureDataFormatter.LocalizeEncoded((grandTotalSum)));
    }
    d.DumpRow(row);
  }
}
