Temporary Hash Table

The Temporary Hash Table icon indicates that a temporary hash table was created in order to perform hash processing. A hash table is a data structure where the table data is collated based upon the value of a column or columns referred to as the hash key. The hash table can then be used to perform probe operation using the hash key to quickly retrieve all of the table data that matches a particular hash value.

Note: A hash table is an internal data structure and can only be created by the system.
