Package dev.frostlake.executor

Class ConditionalDdlOutcome

java.lang.Object

dev.frostlake.executor.ConditionalDdlOutcome

public final class ConditionalDdlOutcome
extends Object

The conditional branch the CURRENT statement's DDL handler took, reported by the handler itself: the status sentence for CREATE … IF NOT EXISTS that found its object, and for DROP … IF EXISTS that did not, depends on what the catalog held a moment BEFORE — a fact only the handler's own skip branch knows. Held in a ThreadLocal and consumed per statement, following StatementClock's pattern: one engine serves many sessions, so this must not be a process-wide setting.
