MySQL Connector/NET Release Notes
Fixes bugs since 6.0.6.
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. --OverflowException at System.Number.ParseDouble(String value, NumberStyles options, NumberFormatInfo numfmt) 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)
MySqlDataAdapter.Update()
generated
concurrency violations for custom stored procedure driven update
commands that used
UpdateRowSource.FirstReturnedRecord
.
(Bug #54895)
Several calls to DataAdapter.Update()
with
intervening changes to DataTable
resulted in
ConcurrencyException
exceptions being
generated.
(Bug #54863)
The MySqlHelper
object did not have an
overloaded version of the ExecuteReader
method that accepted a MySqlConnection
object.
(Bug #54570)
If MySqlDataAdapter
was used with an
INSERT
command where the
VALUES
clause contained an expression with
parentheses in it, and set the
adapter.UpdateBatchSize
parameter to be
greater than one, then the call to
adapter.Update
either generated an exception
or failed to batch the commands, executing each insert
individually.
(Bug #54386)
The method
MySql.Data.Common.QueryNormalizer.CollapseValueList
generated an ArgumentOutOfRangeException
.
(Bug #54152, Bug #53865)
Garbage Collector disposal of a
MySqlConnection
object caused the following
exception:
System.IO.EndOfStreamException: Attempted to read past the end of the stream. MySql.Data.MySqlClient.MySqlStream.ReadFully(Stream stream, Byte[] buffer, Int32 offset, Int32 count) MySql.Data.MySqlClient.MySqlStream.LoadPacket() Outer Exception Reading from the stream has failed. ...
(Bug #53457)
After a timeout exception, if an attempt was made to reuse a connection returned to the connection pool the following exception was generated:
[MySqlException (0x80004005): There is already an open DataReader associated with this Connection which must be closed first.] MySql.Data.MySqlClient.MySqlCommand.CheckState() +278 MySql.Data.MySqlClient.MySqlCommand.ExecuteReader(CommandBehavior behavior) +43 MySql.Data.MySqlClient.MySqlCommand.ExecuteReader() +6 Controls.SimpleCommand.ExecuteReader(String SQL) in ...:323 Albums.GetImagesByAlbum(SimpleCommand Cmd, Int32 iAlbum, String Order, String Limit) in ...:13 Forecast.Page_Load(Object sender, EventArgs e) in ...:70 System.Web.UI.Control.OnLoad(EventArgs e) +99 System.Web.UI.Control.LoadRecursive() +50 System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint) +627
(Bug #53357)
Membership schema creation failed if the default schema collation was not Latin1. (Bug #53174)
EventLog was not disposed in the SessionState provider. (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)
When an application was subjected to increased concurrent load, MySQL Connector/NET generated the following error when calling stored procedures:
A DataTable named \'Procedure Parameters\' already belongs to this DataSet.
(Bug #49118)
In the ADO.NET Entity Data Model Wizard, the time to update a model scaled abnormally as the number of entities increased. (Bug #48791, Bug #12596237)
The INSERT
command was significantly slower
with MySQL Connector/NET 6.x compared to 5.x, when compression was enabled.
(Bug #48243)
When the connection string option “Connection Reset = True” was used, a connection reset used the previously used encoding for the subsequent authentication operation. This failed, for example, if UCS2 was used to read the last column before the reset. (Bug #47153)
Opening a connection in the Visual Studio Server Explorer and choosing to alter an existing routine required another authentication at the server. (Bug #44715)
When batching was used in MySqlDataAdapter
, a
connection was not opened automatically in
MySqlDataAdapter.Update()
. This resulted in
an InvalidOperationException
exception being
generated, with the message text “connection must be valid
and open”.
MySQL Connector/NET has been changed to behave more like SQL Server: if the connection is closed, it is opened for the duration of update operation. (Bug #38411)
Database name was emitted into typed datasets. This prevented users using the configured default database. (Bug #33870)
