Thanks for isolating this to the JDBC `MERGE` path and for linking PR #11730. This does look like a real bug rather than a usage issue: when every column is part of the key, SeaTunnel should not emit `WHEN MATCHED THEN UPDATE SET` with an empty body. In that case the matched branch should simply be omitted so the statement remains valid and unmatched rows can still be inserted. Since you already have a focused fix in #11730, the main next step is review around dialect coverage and regression tests for all-key tables across the affected `MERGE`-based JDBC dialects. Keeping this issue open until that PR lands is the right path. -- This is an automated message from the Apache Git Service.
