Qlikview aggr

Aggr returns an array of values for the expression calculated over the stated dimension or dimensions.

I have been looking at the documentation related to the aggr function recently and tried to use it on qs. But I find it difficult to understand it and I have a few questions about it. Does the dimension of this virtual table aggr need to be consistent with the dimension of the chart? My understanding is that the granularity of the dimensions in aggr needs to be smaller than that of the chart. Because the outside aggregation function needs to aggregate the virtual table twice.

Aggr returns an array of values for the expression calculated over the stated dimension or dimensions. For example, the maximum value of sales, per customer, per region. The Aggr function is used for nested aggregations, in which its first parameter the inner aggregation is calculated once per dimensional value. The dimensions are specified in the second parameter and subsequent parameters. In addition, the Aggr function should be enclosed in an outer aggregation function, using the array of results from the Aggr function as input to the aggregation in which it is nested. Return data type: dual. If sorting criteria are included, the array of values created by the Aggr function, calculated for the dimension, is sorted. This is important when the sort order affects the result of the expression the Aggr function is enclosed in. For details of how to use sorting criteria, see Adding sorting criteria to the dimension in the structured parameter. Basic aggregation functions, such as Sum , Min , and Avg , return a single numerical value whereas the Aggr function can be compared to creating a temporary staged result set a virtual table over which another aggregation can be made. Each dimension in an Aggr function must be a single field, and cannot be an expression calculated dimension. Adding sorting criteria to the dimension in the structured parameter. In its basic form, the argument StructuredParameter in the Aggr function syntax is a single dimension.

This means the dimensions within the aggr may be qlikview aggr with those from the object probably the most common case but it mustn't mandatory.

In addition, the Aggr function should be enclosed in an outer aggregation function, using the array of results from the Aggr function as input to the aggregation in which it is nested. Return data type: dual. An expression consisting of an aggregation function. By default, the aggregation function will aggregate over the set of possible records defined by the selection.

The dimension is a single field and cannot be an expression. Skip to main content Skip to complementary content Close. Hope someone can answer my question. A must-read for enthusiasts and professionals alike. SetExpression : By default, the aggregation function will aggregate over the set of possible records defined by the selection. If the expression argument is preceded by the nodistinct qualifier, each combination of dimension values may generate more than one return value, depending on underlying data structure. This example displays the aggregated values over a twelve month period for each year in chronological ascending order, hence the structured parameters Numeric, Ascending part of the Aggr expression. The StructuredParameter is the dimension on which you would like to aggregate the expression. For more information about using inline loads, see Inline loads. Fields are used to create dimensions and measures in visualizations.

For more generic nesting, you will have to use the advanced aggregation function in combination with calculated dimensions. An obvious question given this data would be: "How many customers does each sales representative have?

However, when enclosed in another aggregation function, there can be unexpected results unless sorting criteria are used. Leave your feedback here. An alternative set of records can be defined by a set analysis expression. However, when enclosed in another aggregation function, there can be unexpected results unless sorting criteria are used. This is necessary for the dimension list of the Aggr function to correspond with the dimensions of the object used in the visualization. StructuredParameter consists of a dimension and optionally, sorting criteria in the format: Dimension Sort-type, Ordering The dimension is a single field and cannot be an expression. Basic aggregation functions, such as Sum , Min , and Avg , return a single numerical value whereas the Aggr function can be compared to creating a temporary staged result set a virtual table over which another aggregation can be made. Going trough the possible answers we can see that while answer A will work for the first four partners, it will quickly run into troubles calculating the average if there are more then two orders. This means the dimensions within the aggr may be identically with those from the object probably the most common case but it mustn't mandatory. Measure A measure is a calculation base on one ore more aggregations. I don't know if my understanding is wrong. Skip to main content Skip to complementary content Close.
