difference is concurrency. With MyISAM, a DML statement would obtain an exclusive lock on the table, and while that lock are held, no other session can Perform a SELECT or a DML operation on the table.Another big difference is concurrency. Using the MYISAM,DML statement will obtain an exclusive lock on the table, and no other session can perform a select or DML operation on the table when the lock is persisted.）Those specific engines you asked about (InnoDB and MyISAM) has different design goal

The CLR environment gives us built-in several commonly used delegate Action, actionFirst, ActionThe action encapsulates a method that has no parameters and no return value, and the declaration prototype is:1 public delegate void Action ();Use the following:1 public void Alert () 2 {3 Console.WriteLine ("This is a Warning"); 4 }5 6 Action T = new action (Alert); instantiate an action delegate of 7 T ();If the statement in the delegate's method is short, you can also use the LAMBD expre
