Package dev.frostlake.types

Class StructuredField

java.lang.Object

dev.frostlake.types.StructuredField

All Implemented Interfaces:

Serializable

public final class StructuredField
extends Object
implements Serializable

One declared field of a structured OBJECT(name type [NOT NULL], ...) type.

The name is kept VERBATIM — structured field names are case-sensitive and are NOT folded like ordinary SQL identifiers. Live-verified on a real account: CAST(OBJECT_CONSTRUCT('x','a') AS OBJECT(x VARCHAR)) yields {"x":"a"} (lower case preserved), CAST(<OBJECT(x VARCHAR)> AS OBJECT(X VARCHAR) RENAME FIELDS) yields {"X":"a"}, and CAST(OBJECT_CONSTRUCT('x','a') AS OBJECT(X VARCHAR)) FAILS with "Typed object schema mismatch in conversion" — the declared X does not match the key x.
