Re: SHOW VARIABLES: which table holds my.cnf startup varibles?
This is still a mystery to me
Looks like mysql has 'hidden' internal tables? true/false?
Is there a way for me to access this tables? or where is the startup variables valued stored? in the memory? or where?
I found the vairables table in information_schema - but I can not select from it
is there a way to do that?
mysql (information_schema)>>desc variables;
+---------------+--------------+------+-----+---------+-------+
| Field | Type | Null | Key | Default | Extra |
+---------------+--------------+------+-----+---------+-------+
| Variable_name | varchar(80) | NO | | | |
| Value | varchar(512) | NO | | | |
+---------------+--------------+------+-----+---------+-------+
2 rows in set (0.00 sec)
mysql (information_schema)>>select value from variables;
ERROR 1109 (42S02): Unknown table 'variables' in information_schema
mysql (mysql)>>select value from variables;
ERROR 1146 (42S02): Table 'mysql.variables' doesn't exist
