We are pleased to announce the technical preview for SQLSRV and PDO_SQLSRV drivers that support the Azure AD access token for Windows, Linux and macOS. Both drivers have been built with PHP 7.1+ and tested on all supported platforms (Windows, Ubuntu 16.04 and 18.04, RedHat 7, Debian 8 and 9, Suse 12, and macOS 10.11, 10.12, and 10.13).

Notable items about the 5.4.0-preview release,

Added

Removed

  • Dropped support for Ubuntu 17.10
  • Dropped support for PHP 7.0 - Version 5.3 is the last to support PHP 7.0.

Fixed

  • Issue #434 - To avoid the pitfall that could result in a crash, before freeing stmt in the destructor check if its dbh driver data is NULL
  • Pull Request #836 - Modified the config files to enable Spectre Mitigations (use /Qspectre switch) for PHP 7.2
  • Pull Request #833 - Streamlined the error handling to remove a potential cause of crash

Limitations

  • No support for inout / output params when using sql_variant type
  • 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

  • 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)
  • With ColumnEncryption enabled, fetching varbinary(max), varchar(max) or nvarchar(max) may fail with ODBC Driver 17.3 CTP
