sorting a hash by key value

[Me]

I have a hash (of a hashes) that has data like this
table1->table_name
->table_size
table2->table_name
->table_size

I need to sort the hash by table_size (numeric). How can I do this.

You don't. Hashes by their very nature don't have an order or sequence.
Therefore the term "sorting a hash" is about as meaningful as trying to sort
the lenght() function. You have to use a different data structure.

Having said that you Question is also Asked Frequently, please see
"perldoc -q sort" for several suggestion about what to do instead.

Do you mean to say you have an array of hash references? that they
themselves have hash references?
