A MySQL database is using a stored function avg_sales in some SQL
queries. I am having a hard time finding the code for this function,
in order to track down a bug that I suspect is in the function. Here
is what I get when I try to query MySQL for the function code:
mysql> SELECT * FROM information_schema.ROUTINES\G
*************************** 1. row ***************************
SPECIFIC_NAME: avg_sales
ROUTINE_CATALOG: NULL
ROUTINE_SCHEMA: ********
ROUTINE_NAME: avg_sales
ROUTINE_TYPE: FUNCTION
DTD_IDENTIFIER: int(11)
ROUTINE_BODY: SQL
ROUTINE_DEFINITION: NULL
EXTERNAL_NAME: NULL
EXTERNAL_LANGUAGE: NULL
PARAMETER_STYLE: SQL
IS_DETERMINISTIC: NO
SQL_DATA_ACCESS: CONTAINS SQL
SQL_PATH: NULL
SECURITY_TYPE: DEFINER

CHARACTER_SET_CLIENT: latin1
COLLATION_CONNECTION: latin1_swedish_ci
DATABASE_COLLATION: utf8_general_ci
2 rows in set (0.00 sec)
mysql> SHOW CREATE FUNCTION avg_sales;

mysql> SELECT param_list,returns,body FROM mysql.proc;
ERROR 1142 (42000): SELECT command denied to user
'********'@'localhost' for table 'proc'

What else should I try to get the code? This is on MySQL 5.1.61
running on CentOS. Thanks.
