How can we see the list, along with complete information, of stored functions in a particular MySQL database?
We can mysql.proc to see the list, along with complete information, of stored functions in a particular MySQL database by the following query −
mysql> Select * from mysql.proc where db = 'query' AND type = 'FUNCTION' \G
*************************** 1. row ***************************
db: query
name: factorial
type: FUNCTION
specific_name: factorial
language: SQL
sql_data_access: CONTAINS_SQL
is_deterministic: YES
security_type: DEFINER
param_list: n DECIMAL(3,0)
returns: decimal(20,0)
body: BEGIN
DECLARE factorial DECIMAL(20,0) DEFAULT 1;
DECLARE counter DECIMAL(3,0);
SET counter = n;
factorial_loop: REPEAT
SET factorial = factorial * counter;
SET counter = counter - 1;
UNTIL counter = 1
END REPEAT;
RETURN factorial;
