The Summary function group provides functions for creating summary fields such as:Copy Sum({Orders.Order Amount}, {Orders.Ship Via}) Summary fields are normally created using the Insert Summary or Insert Grand Total dialogs. Alternatively, you can create a summary field exclusively for use by ...

To build an expression, you combine identifiers by using functions, operators, constants, and values. Any valid expression must contain at least one function or at least one identifier, and can also contain constants or operators. You can also use an expression as part of another expression — ...
A function can have a parameter namedthisas the first parameter, and this parameter (and its type) is ignored by the runtime. It has no effect on thelengthproperty of the function, and does not impact values likearguments. functionsum(this:SomeType,x:number,y:number){// ...} ...

The categories of built-in functions are: Types of Functions Expand table Function CategoryDescription Aggregate Functions Operate on a collection of values but return a single, summarizing value. Analytic Functions Return a value based on defined constraints. Array Functions Ret...
Some of the most common functions include Aggregate function Meaning SUM Calculates the total sum of values in a field COUNTD Counts the number of distinct (unique) values in a field, ignoring duplicates MAX Finds the maximum value in a field MIN Finds the minimum value in a field AVG ...
By contrast, window operations do not collapse groups of query rows to a single output row. Instead, they produce a result for each row. Like the preceding queries, the following query usesSUM(), but this time as a window function: ...
(Ramstead et al.,2018). Free-energy is an information-theoretic quantity and is a function of sensory data and brain states: in brief, it is the upper bound on the ‘surprise’—or surprisal (Tribus,1961)—of sensory data, given predictions that are based on an internal model of how ...
) Function call operator, which indicates the end of the function call. * Multiply. The asterisk (*) is also used in X++ SQL. One use is to signify all fields from the tables on a select statement. Another use is as a wildcard with the like operator, to signify 0 to many character...
