mysql create stored procedure

DELIMITER $$ -- Changes delimiter to $$ so can use ; within the procedure
CREATE PROCEDURE select_employees()
BEGIN
	select * 
	from employees 
	limit 1000; -- Use the ; symbol within the procedure
END$$ 
DELIMITER ; -- Resets the delimiter

DELIMITER $$ -- Changes delimiter to $$ so can use ; within the procedure
CREATE PROCEDURE <Your-procedure-name>(<argument1><argument2>...<argumentN>)
BEGIN
	<Code-that-stored-procedure-executes>; -- Use the ; symbol within the procedure
END$$
DELIMITER ; -- Resets the delimiter

MySQL stored procedure vs function

The most general difference between procedures and functions is that they are invoked differently and for different purposes:

A procedure does not return a value. Instead, it is invoked with a CALL statement to perform an operation such as modifying a table or processing retrieved records.
A function is invoked within an expression and returns a single value directly to the caller to be used in the expression.
You cannot invoke a function with a CALL statement, nor can you invoke a procedure in an expression.
