Microsoft Drivers 5.2.1 Preview for PHP for SQL Server Released!


Hi all,

We are excited to announce a new technical preview for SQLSRV and PDO_SQLSRV drivers. The driver now supports basic CRUD functionalities with the Always Encrypted feature for Windows, Linux and macOS. Both drivers have been built with PHP 7.0+ and tested on all supported platforms (Windows, Ubuntu 16.04 and 17.10, RedHat 7, Debian 8 and 9, Suse 12, and macOS 10.11, 10.12, and 10.13).

Notable items about 5.2.1-preview release:

Added

  • Added support for Azure Key Vault for Always Encrypted for basic CRUD functionalities such that Always Encrypted feature is also available to Linux or macOS users
  • Added support for macOS High Sierra (requires MS ODBC Driver 17+)

Fixed

  • Issue #577 - Idle Connection Resiliency doesn't work with Column Encryption enabled connection
  • Issue #678 - Idle Connection Resiliency doesn't work with Connection Pooling bug
  • Issue #699 - Binding output parameter failed when the query in the stored procedure returned no data. The test case has been added to the test lab.
  • Issue #705 - AE - Retrieving a negative decimal value (edge case) as output parameter causes truncation
  • Issue #706 - AE - Cannot insert double with precision and scale (38, 38)
  • Issue #707 - AE - Fetching decimals / numerics as output parameters bound to PDO::PARAM_BOOL or PDO::PARAM_INT returns floats, not integers
  • Issue #735 - Extended the buffer size for PDO lastInsertId such that data types other than integers can be supported
  • Pull Request #759 - Removed the limitation of binding a binary as inout param as PDO::PARAM_STR with SQLSRV_ENCODING_BINARY
  • Pull Request #775 - Fixed the problem for output params with SQL types specified as SQLSRV_SQLTYPE_DECIMAL or SQLSRV_SQLTYPE_NUMERIC

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 connection will not work
  • Always Encrypted feature, which requires MS ODBC Driver 17+
    • only Windows Certificate Store and Azure Key Vault are supported
    • Issue #716 - With Always Encrypted feature enabled, Named Parameters in Sub Queries are not supported
    • Always Encrypted limitations

Known Issues

  • Connection pooling on Linux or macOS is not recommended with unixODBC < 2.3.6
  • When pooling is enabled on Linux or macOS
    • unixODBC <= 2.3.4 (Linux and macOS) might not return proper diagnostics 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)
