オリジナル版:http://lists.mysql.com/myodbc/11169

MySQLデータベースシステム用ODBCドライバの新バージョンである、MySQL Connector/ODBC 3.51.14がリリースされました。このリリースは、3.51シリーズの最新のリリースであり、MySQL 4.1, 5.0, 5.1を含むいかなるMySQLバージョンの使用にも適応しています。

警告

バージョン3.51.14は製品リリースですが、ビルドプロシージャが変化している事と、この長く遅れたリリースに入った多くのバグフィックスのため、アップグレードの際には注意されるようお勧めします。

バージョン3.51.14はhttp://dev.mysql.com/downloads/connector/odbc/3.51.htmlとミラーサイトのConnector/ODBCダウンロード・ページから、バイナリで現在利用可能です。

すべてのミラーサイトが現在、最新であるとは限らないことに注意してください。
あるミラーサイトでこのバージョンを見つけることができない場合は、再度確認を行うか、あるいは別のダウンロード・サイトを選択してください。

MySQL AB社のJess Balint氏らは、4月下旬に開かれるMySQL Conference & Expoにおいて、ODBCについて講演する予定です。題名は、「Primetime ODBC:ODBC構成のアプリケーションとODBC 5.0ロードマップ」です。

以下は、プラットフォーム注意事項と変更事項です。

Platform notes:
* There are no binary packages for Microsoft Windows x64 Edition --
  these will be provided in a future release.
* The RPM binary packages do not include the GUI bits.
* The Mac OS X binary packages are only provided as tarballs, there is no
  installer for this release.
* There is no binary package for Mac OS X on 64-bit PowerPC because Apple
  does not currently provide a 64-bit PowerPC version of iODBC.
* The HP-UX 11.23 IA64 binary package does not include the GUI bits because
  of problems building Qt on that platform.
* The binary packages for Sun Solaris are only provided as tarballs, not
  the PKG format, for this release.
* There are no binary packages for SCO OpenServer.

Changes since the last release:

  Functionality added or changed:
  * Added auto-reconnect option because automatic reconnect is now
    disabled by default in libmysql
  * Added auto is null option (Bug #10910)
  * Added support for SQLMoreResults
  * Checking SQL_ATTR_CONNECTION_DEAD now always calls mysql_ping() to
    check for a dead connection.
  * Remove ODBC escape syntax { and } that begin and terminate statements,
    allowing {CALL (?)} for procedures that don't require OUT or INOUT
    parameters
  * Improved regression tests
  * Added --with-separate-debug-driver ./configure option

  Bugs fixed:
  * SQL_ATTR_CONNECTION_TIMEOUT was inappropriately mapped to
    MYSQL_OPT_CONNECT_TIMEOUT. (Bug #19823)
  * Prepared statements using the embedded MySQL server would fail
    due to an unitialized variable. (Bug #16535)
  * Fix positioned update and delete on statements derived from one
    table with no primary key but including all columns (Bug #22796)
  * Only initialize the ODBC version when the old-style SQLAllocEnv()
    is called. If SQLAllocHandle() is used, the ODBC version must be
    explicitly specified using a call to SQLSetEnvAttr()
  * On 64-bit systems, some types would be incorrectly returned. (Bug #26024)
  * Using DataAdapter, Connector/ODBC may continually consume memory when
    reading the same records within a loop (Windows Server 2003 SP1/SP2 only).
    (Bug #20459)
  * Fix truncation of queries with leading spaces when SQL_ATTR_MAX_ROWS
    is set to a non-zero value (Bug #6609)
  * Fixed problem with memory allocation in Windows for BLOB and long
    queries that need re-allocation of net->buff
  * Using Connector/ODBC, with SQLBindCol and binding the length to the return
    value from SQL_LEN_DATA_AT_EXEC fails with a memory allocation error.
    (Bug #20547)
  * Fixed Windows-specific problems with the GUI for SQL_DRIVER_PROMPT
  * Fixed issues with numeric and decimal rounding
  * Fixed memory leak in SQLDriverConnect()
  * Fixed serious memory leak in SQLSpecialColumns() (up to 8KB/call)
  * Fixed handle leak in LibMain (Bug #21385, thanks to Leandro Becker)
  * Fixed field lengths reported by SQLDescribeCol() when using functions
    such as COMPRESS() in SELECT queries (Bug #20208)
  * Fixed 64-bit issues related to SQLINTEGER columns defined as int,
    but later cast to long.
  * TIME fields were incorrectly converted into date/time values. (Bug #25846,
    Bug #24867, and Bug #25432)
  * Fixed #Deleted issue in Microsoft Access by changing the default behavior
    of MyODBC driver regarding SQL_AUTO_IS_NULL variable. Added new option to
    the GUI and driver
  * Fixed memory leak in SQLSpecialColumns()
  * Corrected return size of SQLGetStmtAttr() when getting desc handles
  * Fixed SQLGetInfo() of SQL_TXN_CAPABLE to return SQL_TC_DDL_COMMIT
  * For SQL_C_TIME, handle conversion from the different time-related MySQL
    types, instead of always assuming it is just a TIME. (DATETIME, TIMESTAMP,
    and DATE were all handled incorrectly.)
  * Fix crash when default database is not set
  * Fix handling of lost connections (Bug #14639)
  * File DSNs could not be saved. (Bug #12019)
  * Nullability of auto_increment fields is incorrect. (Bug #10130)
  * Connector/ODBC may insert the wrong parameter values when using prepared
    statements under 64-bit Linux. (Bug #22446)
  * The SQLDriverConnect() ODBC method did not work with recent Connector/ODBC
    releases. (Bug #12393)
  * Some properties returned by SQLGetInfo() were set using the wrong data
    type, resulting in possible memory overruns. (Bug #20995)
  * Ending a transaction using SQLEndTran() on a environment handle was
    not supported. (Bug #21588)
