In MySQL, how does one write SQL statements to call stored procedures?

Call sp_add ();
Is there a problem with the process you defined, and the returned results are not pointed out?
Like me:

Create procedure sp_add (a int, B int, out c int)
Begin

Set c = a + B;

End;
Call process:
Call sp_add (1, 2, @ );
Select @;

How does mysql execute block statements without creating functions or stored procedures?

Mysql does not have the concept of blocks. Separate blocks are as follows:
BEGIN
Insert into liu_test VALUE ('A', 'bb ');
END
Such blocks cannot be executed.
The best way to execute a block separately is to create a stored procedure, and delete the stored procedure after execution.
