Class LikeAnyAllExpression

java.lang.Object

dev.frostlake.executor.expressions.LikeAnyAllExpression

All Implemented Interfaces:

Expression

public class LikeAnyAllExpression
extends Object
implements Expression

Snowflake multi-pattern matching: x LIKE ANY (p1, p2, …), x LIKE ALL (…) and x ILIKE ANY (…), with an optional shared ESCAPE. This is NOT the OR/AND expansion of the single-pattern predicate: Snowflake skips NULL patterns entirely (live-verified — 'a' LIKE ALL ('a', NULL) is TRUE and 'a' LIKE ANY ('b', NULL) is FALSE, where three-valued logic would say NULL), returning NULL only for a NULL subject or when every pattern is NULL.
