Node Modifier Functions

This section outlines the syntax of the node modifier functions in FEQL.

Node modifier functions operate on the values of value type nodes within the query graph of a FEQL statement.

NB Recall that all model elements within the model are considered a node in FEQL. I.e. If an Order entity/node has an OrderDate column/property...that corresponds to a value type node in FEQL, and a Value Type in the underlying Object-Role Model.

Viz how the MONTH and YEAR node modifier functions are used in the following FEQL query, converted from the natural language query above it.

Node modifier functions include:

Date
Month
Year
Time
ToLower
ToUpper
Sum
Average
Max
Min
