Changes in MySQL Connector/Net 6.3.4 (2010-09-01, General Availability)

First GA release. This release fixes bugs since 6.3.3.

Bugs Fixed

  • The calculation of lockAge in the Session Provider sometimes generated a System.Data.SqlTypes.SqlNullValueException. (Bug #55701)

  • Attempting to read Double.MinValue from a DOUBLE column in MySQL table generated the following exception:

    System.OverflowException : Value was either too large or too small for a Double.
    at System.Number.ParseDouble(String value, NumberStyles options, NumberFormatInfo
    at MySql.Data.Types.MySqlDouble.MySql.Data.Types.IMySqlValue.ReadValue(MySqlPacket
    packet, Int64 length, Boolean nullVal)
    at MySql.Data.MySqlClient.NativeDriver.ReadColumnValue(Int32 index, MySqlField field,
    IMySqlValue valObject)
    at MySql.Data.MySqlClient.ResultSet.ReadColumnData(Boolean outputParms)
    at MySql.Data.MySqlClient.ResultSet.NextRow(CommandBehavior behavior)
    at MySql.Data.MySqlClient.MySqlDataReader.Read()

    (Bug #55644)

  • Calling MySqlDataAdapter.Update(DataTable) resulted in an unacceptable performance hit when updating large amounts of data. (Bug #55609)

  • If using MySQL Server 5.0.x it was not possible to alter stored routines in Visual Studio. If the stored routine was clicked, and the context sensitive menu option, Alter Routine, selected, the following error was generated:

    Unable to load object with error: Object reference not
    set to an instance of an object

    (Bug #55170)

  • EventLog was not disposed in the SessionState provider. (Bug #52550)

  • When attempting to carry out an operation such as:

    from p in db.Products where p.PostedDate>=DateTime.Now select p;

    Where p.PostedDate is a DateTimeOffset, and the underlying column type is a TIMESTAMP, the following exception was generated:

    MySqlException occurred
    Unable to serialize date/time value

    MySQL Connector/Net has now been changed so that all TIMESTAMP columns will be surfaced as DateTime. (Bug #52550)

  • Stored procedure enumeration code generated an error if a procedure was used in a dataset that did not return any resultsets. (Bug #50671)

  • The INSERT command was significantly slower with MySQL Connector/Net 6.x compared to 5.x, when compression was enabled. (Bug #48243)

  • Opening a connection in the Visual Studio Server Explorer and choosing to alter an existing routine required another authentication at the server. (Bug #44715)
