Question

00:54 Oct 28, 2024

I am trying use AggregationType.Sum for in source code schema for my web service but its not summing the the totals as i wanted to do. It only sends the first records Amount rather than finding the all the records with that condition match and total them up. Can anyone direct me to documentation of implementing this?

var esq = new EntitySchemaQuery(UserConnection.EntitySchemaManager, "UsrExample");

var totalSum = esq.AddColumn("UsrTotal");

totalSum .SummaryType = AggregationType.Sum; // Set aggregation to sum

// Added filters:

FinalAmount= sessionCollection[0].GetTypedColumnValue(totalSum.Name);

Hello Tony,

Example of adding the aggregate column to the query column collection (column must have the SUM aggregation type for all table records):

var esq = this.Ext.create(Terrasoft.EntitySchemaQuery, {
    rootSchemaName: "Activity"
});
esq.addAggregationSchemaColumn("DurationInMinutes", Terrasoft.AggregationType.SUM, "ActivitiesDuration", Terrasoft.AggregationEvalType.ALL);

You can read more in the article from the Academy.

Also I've found one more example in the Community question.

Hi Community!

How are you?

How could I put together a query similar to that with ESQ on the server side? Can I use aggregation functions?

SELECT Max(l.CreatedOn), l.SmrRecordId

FROM SmrLoggingRecord l

   JOIN [dbo].[Case] c

       ON l.SmrRecordId = c.Id

       AND c.UpriEstadoCasoId = '78346E42-83AD-4790-B901-DB750A1D157E'

WHERE l.SmrColumnCaption = 'Estado del Caso'

GROUP BY SmrRecordId

King Regards!

Hi,

There is good description here how to write such queries. When reading pay attention to "Adding columns to query" section there. You can not only use aggregation in queries but also can use aggregation in filters
