…T/UNSET TAG, CREATE WAREHOUSE ... WITH TAG
Route ALTER WAREHOUSE <name> { SET | UNSET } TAG through parse_alter_object_set_tags
(mirroring the ALTER SCHEMA maybe_parse form) so the tag form requires a name and
non-tag forms keep falling through to parse_alter_warehouse. Add if_exists to
Statement::SetTags (also enables ALTER DATABASE|SCHEMA IF EXISTS ... SET TAG). Add
a trailing-only WITH TAG (...) clause to CREATE WAREHOUSE via a new with_tags field.

Design
Supports warehouse tagging grammar for the snowflake-rs emulator (LAV-1595):
ALTER WAREHOUSE [IF EXISTS] <name> { SET TAG <t> = '<v>' [, ...] | UNSET TAG <t> [, ...] }— routed throughparse_alter_object_set_tagsvia amaybe_parsemirror of theALTER SCHEMAtag form. The tag form requires a name; every otherALTER WAREHOUSEform (SET<property>, UNSET, SUSPEND, RESUME, RENAME TO, ABORT ALL QUERIES) and the bare name-less form fall through toparse_alter_warehouseunchanged.Statement::SetTagsgains anif_existsfield, parsed generically inparse_alter_object_set_tags. As a side effectALTER DATABASE|SCHEMA IF EXISTS ... SET TAGnow parse.CREATE [OR REPLACE] WAREHOUSE <name> [<properties>] WITH TAG (<t> = '<v>' [, ...])— new trailing-onlywith_tagsfield onStatement::CreateWarehouse. Properties after the tag clause are a syntax error, matching Snowflake.🤖 Generated with Claude Code
