Limitations
- No support for inout / output params when using sql_variant type
- No support for inout / output params when formatting decimal values
- In Linux and macOS, setlocale() only takes effect if it is invoked before the first connection. Attempting to set the locale after connecting will not work
- Always Encrypted requires MS ODBC Driver 17+
- Only Windows Certificate Store and Azure Key Vault are supported. Custom Keystores are not yet supported
- Issue #716 - With Always Encrypted enabled, named parameters in subqueries are not supported
- Always Encrypted limitations
Known Issues
- Data Classification metadata retrieval is not compatible with ODBC Driver 17.4.1
- Connection pooling on Linux or macOS is not recommended with unixODBC < 2.3.7
- When pooling is enabled in Linux or macOS
- unixODBC <= 2.3.4 (Linux and macOS) might not return proper diagnostic information, such as error messages, warnings and informative messages
- due to this unixODBC bug, fetch large data (such as xml, binary) as streams as a workaround. See the examples here
- With ColumnEncryption enabled, calling stored procedures with XML parameters does not work (Issue #674)
