Public Methods

Method	Description
BeginExecuteNonQuery ( ) : IAsyncResult	Initiates the asynchronous execution of the SQL statement or stored procedure that is described by this MySqlCommand.
BeginExecuteNonQuery ( AsyncCallback callback, object stateObject ) : IAsyncResult	Initiates the asynchronous execution of the SQL statement or stored procedure that is described by this MySqlCommand.
BeginExecuteReader ( ) : IAsyncResult	Initiates the asynchronous execution of the SQL statement or stored procedure that is described by this MySqlCommand, and retrieves one or more result sets from the server.
BeginExecuteReader ( CommandBehavior behavior ) : IAsyncResult	Initiates the asynchronous execution of the SQL statement or stored procedure that is described by this MySqlCommand using one of the CommandBehavior values.
Cancel ( ) : void	Attempts to cancel the execution of a currently active command Cancelling a currently active query only works with MySQL versions 5.0.0 and higher.
Clone ( ) : MySqlCommand	Creates a clone of this MySqlCommand object. CommandText, Connection, and Transaction properties are included as well as the entire parameter list.
CreateParameter ( ) : MySqlParameter	Creates a new instance of a MySqlParameter object. This method is a strongly-typed version of IDbCommand.CreateParameter.
EndExecuteNonQuery ( IAsyncResult asyncResult ) : int	Finishes asynchronous execution of a SQL statement.
EndExecuteReader ( IAsyncResult result ) : MySqlDataReader	Finishes asynchronous execution of a SQL statement, returning the requested MySqlDataReader.

AddToBatch ( MySqlCommand command ) : void
AsyncExecuteWrapper ( int type, CommandBehavior behavior ) : object
CheckState ( ) : void	Check the connection to make sure - it is open - it is not currently being used by a reader - and we have the right version of MySQL for the requested command type

EstimatedSize ( ) : long
GetCommandTextForBatching ( ) : string
HandleCommandBehaviors ( CommandBehavior behavior ) : void
ICloneable ( ) : object
Prepare ( int cursorPageSize ) : void
ResetReader ( ) : void	Reset reader to null, to avoid "There is already an open data reader" on the next ExecuteReader(). Used in error handling scenarios.
ResetSqlSelectLimit ( ) : void	Reset SQL_SELECT_LIMIT that could have been modified by CommandBehavior.
TrimSemicolons ( string sql ) : string

Method Details

BeginExecuteNonQuery() public method

Initiates the asynchronous execution of the SQL statement or stored procedure that is described by this MySqlCommand.

public BeginExecuteNonQuery ( ) : IAsyncResult
return	IAsyncResult

BeginExecuteNonQuery() public method

Initiates the asynchronous execution of the SQL statement or stored procedure that is described by this MySqlCommand.

public BeginExecuteNonQuery ( AsyncCallback callback, object stateObject ) : IAsyncResult
callback	AsyncCallback	/// An delegate that is invoked when the command's /// execution has completed. Pass a null reference (Nothing in Visual Basic) /// to indicate that no callback is required.
stateObject	object	A user-defined state object that is passed to the /// callback procedure. Retrieve this object from within the callback procedure /// using the property.
return	IAsyncResult

BeginExecuteReader() public method

Initiates the asynchronous execution of the SQL statement or stored procedure that is described by this MySqlCommand, and retrieves one or more result sets from the server.

public BeginExecuteReader ( ) : IAsyncResult
return	IAsyncResult

BeginExecuteReader() public method

Initiates the asynchronous execution of the SQL statement or stored procedure that is described by this MySqlCommand using one of the CommandBehavior values.

public BeginExecuteReader ( CommandBehavior behavior ) : IAsyncResult
