Research direction

Start with the coverage PR's tests/ diff and trace session.getTables() for METADATA-035, checking the empty tableTypes behavior. Then inspect the SEA metadata path for METADATA-036 and its statement-close handling. Done means the referenced xfail cases become green for both tableTypes=[] behavior and CLOSED metadata statements.

Written by the indexing model from the issue text.

Description

Summary

Surfaced by the multi-language coverage fan-out while conformance-testing these SPEC-IDs against databricks/databricks-sql-nodejs. Each finding is committed as an expected-failure (xfail) test in the coverage PR — the test asserts the CORRECT (post-fix) behavior and stays red until THIS driver (databricks/databricks-sql-nodejs) is fixed, then flips green as a tripwire.

Findings

  • METADATA-035 [thrift, sea]: session.getTables() treats an empty tableTypes array as "match none" and returns 0 rows instead of behaving like a null filter and matching ALL table types (adbc-drivers/hiveserver2#72)
    • failing test: getTables — tableTypes=[] (empty, non-null) matches ALL table types [xfail: driver bug] [thrift], getTables — tableTypes=[] (empty, non-null) matches ALL table types [xfail: driver bug] [sea] (see the coverage PR diff under tests/)
  • METADATA-036 [sea]: the SEA metadata path sends a redundant CloseStatement DELETE even when the metadata ExecuteStatement response reported status.state=CLOSED; the driver's regular-query path honors the terminal state correctly, so this is metadata-specific
    • failing test: METADATA-036 — metadata statement close honors ExecuteStatement status.state [sea] (see the coverage PR diff under tests/)
