mysql - Trying to figure out how to create this procedure -

-

i can't seem figure out , i've been @ sometime great thank you.

i have prepare simple procedure accepting 1 parameter, date value, , using date addition functions in sql (mysql if possible) return parameter value minus 1 day

create procedure get_date  begin date_add(date,interval expr type) end; / exec get_date

this come far. appreciated.

that question not select statement (ie, computing minus 1 day); need sql procedure.

maybe create function

create function simplefunction (s datetime)    returns datetime deterministic    return date_sub(s, interval 1 day);  select simplefunction (anydate);
