MySQL Connector/Net 5.0.1ベータがリリースされました。


MySQL Connector/Net 5.0.1ベータがリリースされました。MySQL Connector/Netは、MySQL用の全てが管理されたADO.Netプロバイダーです。このリリースは、MySQLのどのバージョンにも対応していますが、このリリースを他のいかなる製品のデータにも使用しないことを強くお勧めします。このリリースは、System.TransactionsのDTCサポートを除く機能を完備しています。



* Support for ADO.Net 2.0 interfaces and subclasses

  (this release now includes foreign key support)


* Re-architected to improve speed and flexibility


The internals of the provider have been improved to allow column values to
be retrieved without boxing in many cases.  Also, the internal changes have
enabled the future inclusion of embedded and client library support.


* Implemented Usage Advisor


The Usage Advisor first appeared in Connector/J.  We have now implemented
that feature in Connector/Net.  Enabling it causes the provider to check
both your queries and how you read the results and report to you if it
thinks you are using the provider in an  inefficient manner.  It checks such
things as using a query without an index, not reading all the columns or
rows from a resultset, etc.


* Implemented asynchronous query methods


The MySqlCommand object now supports asynchronous queries.  This is
implemented using the BeginExecuteNonQuery and EndExecuteNonQuery methods.
BeginExecuteReader and EndExecuteReader are now included.


* Implemented stored procedure metadata caching


We now cache the metadata that is retrieved during stored procedure and
stored function execution.  This cache data is used for subsequent
executions of that stored routine.


* Added PerfMon hooks


This release includes PerfMon hooks to monitor stored procedure cache hits
and misses.  We are looking at adding additional hooks in the first beta


* Removed use of SharpZipLib library


We have replaced use of the SharpZipLib library with the deflate support
available with .NET 2.0.



Support for embedded server and client library has been removed


For those of you that have seen my presentations on 5.0, we decided to
remove these features to help get 5.0 out the door more quickly.  These
features will reappear in a later version of the product.
