BaseCommandInterceptor
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 20.2.5.11, “Using the Connector/Net Interceptor Classes” .
20.2.7.1.3.
BaseExceptionInterceptor
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.
