Daevid,
I have a 'users' table. And there are all kinds of related
tables like 'logs', 'preferences', etc. that all have a FK
reference back to this user ID.
I want to make a query or use some PHP to build a list of
all tables in my DB that are references.
Query to find tables with FK references to $db.$table:
SELECT c.table_schema,u.table_name,u.column_name,u.referenced_column_name
FROM information_schema.table_constraints AS c
INNER JOIN information_schema.key_column_usage AS u
USING( constraint_schema, constraint_name )
WHERE c.constraint_type = 'FOREIGN KEY' .
AND u.referenced_table_schema='$db'
AND u.referenced_table_name = '$table'
ORDER BY c.table_schema,u.table_name;
PB

Is there a way with InnoDB tables to see all related tables/columns?
Basically what I want to do is make a script that somehow will dynamically
create a "backup" of a single user record. But I don't want to have to
manually add a new table or column everytime to the script.
So for example, I have a 'users' table. And there are all kinds of related
tables like 'logs', 'preferences', etc. that all have a FK reference back to
this user ID.
I want to make a query or use some PHP to build a list of all tables in my
DB that are references.
Then I can just dump out that user ID (via this script) and it will backup
that user and all related table data across all tables.
