We have released Microsoft Drivers for PHP for SQL Server, version 5.9.0. This production release of the SQLSRV and PDO_SQLSRV drivers has been built with PHP 7.3, 7.4, and 8.0 and tested on all supported platforms.
Notable items about this release since the previous production release include:
Added
Removed
- Dropped support for PHP 7.2
- Dropped support for macOS High Sierra, Ubuntu 19.10 and Debian 8
Fixed
- Pull Request #1127 - removed TSRMLS macros in preparation for PHP 8 by remicollet
- Pull Request #1136 - improved performance when handling decimal numbers as inputs or outputs and removed unnecessary conversions for numeric values
- Pull Request #1143 - if an exception occurs when executing a query, it will not change the output parameters
- Pull Request #1144 - use the correct C types when binding output parameters with integer values
- Pull Request #1146 - improved performance when fetching numbers using client buffers
- Pull Request #1165 - set query timeout without using LOCK TIMEOUT, which saves an extra trip to the server
- Issue #1170 - when fetching large data types such as ntext, check more than only the display size - pull request #1172
- Pull Request #1205 - minimized compilation warnings on Linux and macOS
- Pull Request #1209 - fixed a bug when fetching varbinary max fields as char or wide chars
- Issue #1210 - switched from preview to beta terminology to enable Pickle support
- Issue #1213 - the MACOSX_DEPLOYMENT_TARGET in config files caused linker errors in macOS Big Sur - Pull Request #1215
- Pull Request #1226 - replaced the problematic strlen function
- Pull Request #1227 - addressed static code analyis issues
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
- 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.
