CAST

Renames the elements and changes the data type of each element for the given struct value based on the data type in the specified complex data type definition.

Syntax

CAST (:Type.type_definition_library.type_definition, struct_value)

The following table describes the arguments for this command:

Argument	Required/Optional	Description
:Type.type_definition_library.type_definition	Required	The complex data type definition that represents the schema of the struct data. Use the reference qualifier :Type to reference the type definition library that contains the complex data type definition.
struct_value	Required	The struct value for which you want to change the data type of the struct elements. You can enter any valid transformation expression that evaluates to a struct.

The data type of the struct value and the data type in the complex data type definition must be compatible.

Return Value

Struct.

Examples

The following expression changes the data types of the elements in the struct port h2_sales based on the data types in the complex data type definition h1_sales_def.

CAST (:Type.type_definition_library.h1_sales_def, h2_sales)

h1_sales_def	h2_sales	RETURN VALUE
{ q1_total : bigint q2_total : double }	{ q3_total : int q4_total : int }	{ q1_total : bigint q2_total : double }
