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
