Calling GetSchema() on Indexes or IndexColumns failed where index or column names were restricted.

In SchemaProvider.cs, methods GetIndexes() and GetIndexColumns() passed their restrictions directly to GetTables(). This only worked if the restrictions were no more specific than schemaName and tableName. If IndexName was given, this was passed to GetTables() where it was treated as TableType. As a result no tables were returned, unless the index name happened to be BASE TABLE or VIEW. This meant that both methods failed to return any rows. (Bug#43991)

The DATETIME format contained an erroneous space. (Bug#41021)

If connection pooling was not set explicitly in the connection string, MySQL Connector/NET added “;Pooling=False” to the end of the connection string when MySqlCommand.ExecuteReader() was called.

If connection pooling was explicitly set in the connection string, when MySqlConnection.Open() was called it converted “Pooling=True” to “pooling=True”.

If MySqlCommand.ExecuteReader() was subsequently called, it concatenated “;Pooling=False” to the end of the connection string. The resulting connection string was thus terminated with “pooling=True;Pooling=False”. This disabled connection pooling completely. (Bug#40091)

MySQL Connector/NET generated the following exception:

If, when using the MySqlTransaction transaction object, an exception was thrown, the transaction object was not disposed of and the transaction was not rolled back. (Bug#39817)

When a prepared insert query is run that contains an UNSIGNED TINYINT in the parameter list, the complete query and data that should be inserted is corrupted and no error is thrown. (Bug#37968)

Calling MySqlDataAdapter.FillSchema on a SELECT statement that referred to a table that did not exist left the connection in a bad state. After this call, all SELECT statements returned an empty result set. If the SELECT statement referred to a table that did exist then everything worked as expected. (Bug#30518)
