UPDATE a FROM db1.table1 a, db2.tabl2 b SET ...now parses withDialect.TERADATA. Reuse the existing UPDATE source/join model and add a clause-position flag, with shared FROM parsing and rendering for the AST and deparser. Table discovery and metadata validation recognize target aliases declared in the early FROM clause.Existing dialects retain FROM-after-SET behavior. Tests cover the issue reproducer, aliases and quoted names, round-trips, custom expression deparsing, AST edits, statement boundaries, malformed input and dialect isolation. Full Gradle check and Maven verify passed; the local formatter ratchet uses upstream base
eddb1fb5because the fork's master is behind.Fixes #891.
Syntax: Teradata UPDATE, joined tables form.
