• Fixed issue output parameters bound to empty string (issue #182).
• Fixed a memory leak in closing connection resources.
• Fixed load ordering issue in MacOS (issue #417)
• Added a workaround for a bug in unixODBC 2.3.4 when connection pooling is enabled.
• Fixed the issue with driver loading order in macOS
• Fixed null returned when an empty string is set to an output parameter (issue #308).

  • Fixed sqlsrv client buffer size to only allow positive integers (issue #228).
  • Fixed sqlsrv_num_rows() when the client buffered result is null (issue #330).
  • Fixed issues with sqlsrv_has_rows() to prevent it from moving statement cursor (issue #37).
  • Fixed conversion warnings because of some const chars (issue #332).
  • Fixed debug abort error when building the driver in debug mode with PHP 7.1.
  • Fixed string truncation when binding varchar(max), nvarchar(max), varbinary(max), and xml types (issue #231).

  • Fixed fatal error when calling sqlsrv_fetch() with an out of bound offset for SQLSRV_SCROLL_ABSOLUTE (issue #223).

• Fixed in PDO_SQLSRV

  • Improved performance by implementing a cache to store column SQL types and display sizes (issue #189).
  • Fixed segmentation fault with PDOStatement::getColumnMeta() when the supplied column index is out of range (issue #224).
  • Fixed issue with the unsupported attribute PDO::ATTR_PERSISTENT in connection (issue #65).
  • Fixed the issue with executing DELETE operation on a non-existent value (issue #336).
  • Fixed incorrectly binding of unicode parameter when emulate prepare is on and the encoding is set at the statement level (issue #92).
  • Fixed binary column binding when emulate prepare is on (issue #140).
  • Fixed wrong value returned when fetching varbinary value on Linux (issue #270).
  • Fixed binary data not returned when the column is bound by name (issue #35).
  • Fixed exception thrown on closeCursor() when the statement has not been executed (issue #267).

Limitation

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

Known Issues

• When pooling is enabled in Linux or MAC
  • unixODBC <= 2.3.4 (Linux and MAC) 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
