  • 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
    • Issue #1050 - With Always Encrypted enabled, insertion requires the column list for any tables with identity columns
    • Always Encrypted limitations

Known Issues

  • This release requires ODBC Driver 17.4.2 or above. Otherwise, a warning about failing to set an attribute may be suppressed when using an older ODBC driver.
  • 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


Let us know how we are doing and how you use our drivers by taking our pulse survey.



  • On Linux and macOS run the commands below:



sudo pecl install sqlsrv-5.10.0beta1
sudo pecl install pdo_sqlsrv-5.10.0beta​1
