EXTRACT_STRUCT

Extracts all elements from a dynamic struct port in an Expression transformation. Use the dot operator in expressions to extract elements of a struct. For more information on using the dot operator, see the

Data Engineering Integration User Guide

When you use the EXTRACT_STRUCT function, you must specify a base port in which you set the dynamic struct field that is being used as the argument.

You cannot nest other functions within the EXTRACT_STRUCT function or nest the EXTRACT_STRUCT function in another function.

Syntax

EXTRACT_STRUCT(dynamic_struct1)

The following table describes the arguments for this command:

Argument	Required/Optional	Description
Dynamic struct	Required	Extracts all elements from a dynamic struct port in an Expression transformation.

Return Value

Dynamic type consisting of all the struct elements as generated fields.

Example

The following function extracts and flattens a dynamic struct:

EXTRACT_STRUCT(Struct_emp_info_struct_as)
