In the MySqlDataReader class the GetSByte function returned a byte value instead of an sbyte value. (Bug#46620)

When trying to create stored procedures from a SQL script, a MySqlException was thrown when attempting to redefine the DELIMITER:

        MySql.Data.MySqlClient.MySqlException was unhandled
        Message="You have an error in your SQL syntax; check the manual that corresponds to your
        MySQL server version for the right syntax to use near 'DELIMITER' at line 1"

The MySQL Connector/NET Profile Provider, MySql.Web.Profile.MySQLProfileProvider, generated an error when running on Mono. When an attempt was made to save a string in Profile.Name the string was not saved to the my_aspnet_Profiles table. If an attempt was made to force the save with Profile.Save() the following error was generated:

        Server Error in '/mono' Application

An exception was generated when using TIMESTAMP columns with the Entity Framework. (Bug#46311)

MySQL Connector/NET sometimes hung, without generating an exception. This happened if a read from a stream failed returning a 0, causing the code in LoadPacket() to enter an infinite loop. (Bug#46308)

When using MySQL Connector/NET 6.0.4 and a MySQL Server 4.1 an exception was generated when trying to execute:

        connection.GetSchema("Columns", ...);
      

The exception generated was:

        'connection.GetSchema("Columns")' threw an exception of type
        'System.ArgumentException'System.Data.DataTable {System.ArgumentException}
        base{"Input string was not in a correct format.Couldn't store <'Select'> in
        NUMERIC_PRECISION Column.  Expected type is UInt64."}System.Exception
        {System.ArgumentException}
      

(Bug#46270)

The MySQL Connector/NET method StoredProcedure.GetParameters(string) ignored the programmer's setting of the UseProcedureBodies option. This broke any application for which the application's parameter names did not match the parameter names in the Stored Procedure, resulting in an ArgumentException with the message “Parameter 'foo' not found in the collection.” and the following stack trace:

Conversion of MySQL TINYINT(1) to boolean failed. (Bug#46205, Bug#46359, Bug#41953)

When populating a MySQL database table in Visual Studio using the Table Editor, if a VARCHAR(10) column was changed to a VARCHAR(20) column an exception was generated:

        SystemArgumentException: DataGridViewComboBoxCell value is not valid.
      To replace this default dialog please handle the DataError Event.

(Bug#46100)

The Entity Framework provider was not calling DBSortExpression correctly when the Skip and Take methods were used, such as in the following statement:

        TestModel.tblquarantine.OrderByDescending(q => q.MsgDate).Skip(100).Take(100).ToList();
      

This resulted in the data being unsorted. (Bug#45723)

The MySQL Connector/NET 6.0.4 installer failed with an error. The error message generated was:

        There is a problem with this Windows Installer package. A DLL required for this
        install to complete could not be run. Contact your support personnel or package vendor.
      

When OK was clicked to acknowledge the error the installer exited. (Bug#45474)

Calling the Entity Framework SaveChanges() method of any MySQL ORM Entity with a column type TIME, generated an error message:

Unknown PrimitiveKind Time

(Bug#45457)

Insert into two tables failed when using the Entity Framework. The exception generated was:

        The value given is not an instance of type 'Edm.Int32'
      

(Bug#45077)

Errors occurred when using the Entity Framework with cultures that used a comma as the decimal separator. This was because the formatting for SINGLE, DOUBLE and DECIMAL values was not handled correctly. (Bug#44455)

When attempting to connect to MySQL using the Compact Framework version of MySQL Connector/NET, an IndexOutOfRangeException exception was generated on trying to open the connection. (Bug#43736)

When reading data, such as with a MySqlDataAdapter on a MySqlConnection, MySQL Connector/NET could potentially enter an infinite loop in CompressedStream.ReadNextpacket() if compression was enabled. (Bug#43678)

An error occurred when building MySQL Connector/NET from source code checked out from the public SVN repository. This happened on Linux using Mono and Nant. The Mono JIT compiler version was 1.2.6.0. The Nant version was 0.85.

When an attempt was made to build (for example) the MySQL Connector/NET 5.2 branch using the command:

        $ nant -buildfile:Client.build
      

The following error occurred:

        BUILD FAILED

        Error loading buildfile.
        Encoding name 'Windows-1252' not supported.
        Parameter name: name
      

(Bug#42411)

MySQL Connector/NET CHM documentation stated that MySQL Server 3.23 was supported. (Bug#42110)

In the case of long network inactivity, especially when connection pooling was used, connections were sometimes dropped, for example, by firewalls.

Note: The bugfix introduced a new keepalive parameter, which prevents disconnects by sending an empty TCP packet after a specified timeout. (Bug#40684)

Calling a Stored Procedure with an output parameter through MySQL Connector/NET resulted in a memory leak. Calling the same Stored Procedure without an output parameter did not result in a memory leak. (Bug#36027)
