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+

Changed

  • Code structure is updated to facilitate the development; shared codes between both drivers are moved to "shared" folder to avoid code duplication issues in development. To build the driver from source:
    • if you are building the driver from source using PHP source, copy the "shared" folder as a subfolder to both the sqlsrv and pdo_sqlsrv folders.

Linux 4.0.8 - 2016-12-19

Production release of Linux drivers is available for Ubuntu 15.04, Ubuntu 16.04, and RedHat 7.2. Here is the list of updates:

  • Added SQLSRV_ATTR_FETCHES_NUMERIC_TYPE attribute support in PDO_SQLSRV driver.SQLSRV_ATTR_FETCHES_NUMERIC_TYPE connection attribute flag handles numeric fetches from columns with numeric Sql types (only bit, integer, smallint, tinyint, float and real). This flag can be turned on by setting its value in PDO::setAttribute to true, For example, $conn->setAttribute(PDO::SQLSRV_ATTR_FETCHES_NUMERIC_TYPE,true); If SQLSRV_ATTR_FETCHES_NUMERIC_TYPE is set to true the results from an integer column will be represented as an int, likewise, Sql types float and real will be represented as float. Note for exceptions:
    • When connection option flag ATTR_STRINGIFY_FETCHES is on, even when SQLSRV_ATTR_FETCHES_NUMERIC_TYPE is on, the return value will still be string.

Added

  • Ported buffered cursor to Linux.

Changed

  • Code structure is updated to facilitate the development; shared codes between both drivers are moved to "shared" folder to avoid code duplication issues in development. To build the driver from source, use "packagize" script as follows:
    • if you are using the phpize, clone or download the “source”, run the script within the “source” directory and then run phpize.
    • if you are building the driver from source using PHP source, give the path to the PHP source to the script.

Fixed

    SQLSRV_SQLTYPE_CHAR char SQL_CHAR
    SQLSRV_SQLTYPE_NCHAR nchar SQL_WCHAR

    SQLSRV_SQLTYPE_NVARCHAR nvarchar SQL_WVARCHAR
    SQLSRV_SQLTYPE_BINARY binary SQL_BINARY
    SQLSRV_SQLTYPE_VARBINARY varbinary SQL_VARBINARY

    Note: These constants should be used in type comparison operations (refer to issue #87 and #99 ), and don't replace the function like constants with similar syntax. For binding parameters you should use the function-like constants, otherwise you'll get an error.

Windows 4.1.0 - 2016-07-28

Fixed

  • SQLSRV_ATTR_FETCHES_NUMERIC_TYPE connection attribute flag is added to PDO_SQLSRV driver to handle numeric fetches from columns with numeric Sql types (only bit, integer, smallint, tinyint, float and real). This flag can be turned on by setting its value in PDO::setAttribute to true, For example, $conn->setAttribute(PDO::SQLSRV_ATTR_FETCHES_NUMERIC_TYPE,true); If SQLSRV_ATTR_FETCHES_NUMERIC_TYPE is set to true the results from an integer column will be represented as an int, likewise, Sql types float and real will be represented as float. Note for exceptions:
    • When connection option flag ATTR_STRINGIFY_FETCHES is on, even when SQLSRV_ATTR_FETCHES_NUMERIC_TYPE is on, the return value will still be string.
    • When the returned PDO type in bind column is PDO_PARAM_INT, the return value from a integer column will be int even if SQLSRV_ATTR_FETCHES_NUMERIC_TYPE is off.
  • Fixed float truncation when using buffered query.
  • Fixed handling of Unicode strings and binary when emulate prepare is on in PDOStatement::bindParam. To bind a unicode string, PDO::SQLSRV_ENCODING_UTF8 should be set using $driverOption, and to bind a string to column of Sql type binary, PDO::SQLSRV_ENCODING_BINARY should be set.
  • Fixed string truncation in bind output parameters when the size is not set and the length of initialized variable is less than the output.
  • Fixed bind string parameters as bidirectional parameters (PDO::PARAM_INPUT_OUTPUT ) in PDO_SQLSRV driver. Note for output or bidirectional parameters, PDOStatement::closeCursor should be called to get the output value.
