SQL 2025 Gotcha

SQL 2025 is GA and SQL 2016 is on it’s end of life on Jul 14, 2026. Some changes in SQL 2025 might break things working before. SQL 2025 uses MSOLEDBSQL 19, and its defaults are different from what we have been using, like with old SQL Native Client (SQLNCLI). In SQL 2025, encrypt is on by default, trust server certification is off by default, and it enforces strick certificate chain validation.
