Pdo\Dblib::ATTR_CONNECTION_TIMEOUT
Pdo\Dblib::ATTR_QUERY_TIMEOUT
Pdo\Dblib::ATTR_STRINGIFY_UNIQUEIDENTIFIER
Pdo\Dblib::ATTR_VERSION
Pdo\Dblib::ATTR_TDS_VERSION
Pdo\Dblib::ATTR_SKIP_EMPTY_ROWSETS
Pdo\Dblib::ATTR_DATETIME_CONVERT: This connection attribute controls the format of strings for datetime types. When this is false, PDO_DBLIB will return a datetime type as a string in the format that SQL Server returns it in (i.e. "2017-10-27 10:22:44"). When true, PDO_DBLIB will convert the datetime type into a string using a user-defined or locale format, as specified in the FreeTDS locales.conf file. By default, this attribute is false.
