Delegates
Delegate | Description |
---|---|
MySqlInfoMessageEventHandler | Represents the method that will handle the InfoMessage event of a MySqlConnection. |

The BaseCommandInterceptor
class has these methods that you can override:
public virtual bool ExecuteScalar(string sql, ref object returnValue);public virtual bool ExecuteNonQuery(string sql, ref int returnValue);public virtual bool ExecuteReader(string sql, CommandBehavior behavior, ref MySqlDataReader returnValue);public virtual void Init(MySqlConnection connection);
If your interceptor overrides one of the Execute...
methods, set the returnValue
output parameter and return true
if you
handled the event, or false
if you did not handle the event. The SQL command is
processed normally only when all command interceptors return false
.
The connection passed to the Init
method is the connection that is attached to
this interceptor.
For full usage and examples, see Section 22.2.5.11, "Using the Connector/Net Interceptor Classes".
You develop an exception interceptor first by creating a subclass of the BaseExceptionInterceptor
class. You must override the InterceptException()
method. You can also override
the Init()
method to do some one-time initialization.
Each exception interceptor has 2 methods:
public abstract Exception InterceptException(Exception exception, MySqlConnection connection);public virtual void Init(MySqlConnection connection);
The connection passed to Init()
is the connection that is attached to this
interceptor.
Each interceptor is required to override InterceptException
and return an
exception. It can return the exception it is given, or it can wrap it in a new exception. We currently do
not offer the ability to suppress the exception.
For full usage and examples, see Section 22.2.5.11, "Using the Connector/Net Interceptor Classes".
