mysq 存储过程怎么调用自定义函数

call
或，如果在select中调用，直接写func()
~~~~~~~~~~~~~~~~~~~~~~~
mysql> delimiter $$
mysql> CREATE FUNCTION isodd(input_number int) //创建函数
-> RETURNS int
-> BEGIN
-> DECLARE v_isodd INT;
->
-> IF MOD(input_number,2)=0 THEN
-> SET v_isodd=FALSE;
-> ELSE
-> SET v_isodd=TRUE;
-> END IF;

-> RETURN(v_isodd);

-> END$$

mysql> CREATE PROCEDURE myProc(aNumber int) //创建mysql存储过程
-> Begin
-> IF (isodd(aNumber)) THEN
