/*

Delimiters other than the default ; are typically used when defining functions, stored procedures, and triggers wherein you must define multiple statements. You define a different delimiter like $$ which is used to define the end of the entire procedure, but inside it, individual statements are each terminated by ;. That way, when the code is run in the mysql client, the client can tell where the entire procedure ends and execute it as a unit rather than executing the individual statements inside.

Note that the DELIMITER keyword is a function of the command line mysql client (and some other clients) only and not a regular MySQL language feature. It won't work if you tried to pass it through a programming language API to MySQL. Some other clients like PHPMyAdmin have other methods to specify a non-default delimiter.

/* Example:*/

DELIMITER $$
/* This is a complete statement, not part of the procedure, so use the custom delimiter $$ */
DROP PROCEDURE my_procedure$$

/* Now start the procedure code */
CREATE PROCEDURE my_procedure ()
BEGIN    
  /* Inside the procedure, individual statements terminate with ; */
  CREATE TABLE tablea (
     col1 INT,
     col2 INT
  );

  INSERT INTO tablea
    SELECT * FROM table1;

  CREATE TABLE tableb (
     col1 INT,
     col2 INT
  );
  INSERT INTO tableb
    SELECT * FROM table2;
  
/* whole procedure ends with the custom delimiter */
END$$

/* Finally, reset the delimiter to the default ; */
DELIMITER ;
