MySQL Connector/ODBC 是 MySQL 数据库的官方 .NET 平台驱动程序。

MySQL Connector/Net 6.7.4 发布了,下载地址:http://dev.mysql.com/downloads/connector/net/6.7.html

这是一个稳定版,修复了如下 bug:

  • The installation of "MySQL for Visual Studio 1.0.2" was broken after installing Connector/NET 6.7.x, because the data provider was not found after uninstalling MySQL for Visual Studio. (Bug #16973456)

  • The LINQ query would return the error "An error of "Unknown column 'Distinct1.nCdSite' in 'where clause'" when using Distinct().Count(). (Bug #16950146, Bug #68513)

  • When the IIS application pool reset the worker processes at a specific time, the MySQL session state store would crash the w3wp.exe process and the request resulted in a crash error message. There are no longer ASP.NET crash yellow pages or bad exceptions. Session expiration is now handled properly. (Bug #16909237, Bug #67665)

  • When using automatic migrations in Entity Framework 5.0, the database objects were given the 'dbo' prefix. This incorrect prefix is no longer generated. (Bug #16909439)

  • An "DBUpdateException saving changes" exception was thrown while inserting data that had Identify columns. The data is now stored in the table.

    A workaround was to set global sql_mode = "ANSI";. (Bug #16494585)

  • Generated "LINQ to Entities" queries are no longer as nested. In other words, two similar queries with one nested inside the other are now flattened into a simple query. This provides better performance for large result sets. (Bug #65723, Bug #16973939)

  • An exception was thrown when populating DataTable with query fields containing aUNIQUE index or constraint NULL. There is no longer an exception thrown, and theDataTable.Fill method terminates correctly (filling the data). (Bug #65065, Bug #16952323)

  • Sometimes data was not returned when a socket connection was slow, interrupted, or delayed. The timeout is now properly reported as an error to the upper layers. (Bug #69039, Bug #16950212)

  • Using a nested projection causes a malformed query to be created, and spurious data to be returned. (Bug #67183, Bug #16872852)
