HASHROW is particularly useful for identifying the statistical properties of the current primary index, or to evaluate these properties for other columns to determine their suitability as a future primary index. You can also use these statistics to help minimize hash synonyms and enhance the uniformity of data distribution.
There are a maximum of 4,294,967,295 hash codes available in the system, ranging from '00000000'XB to 'FFFFFFFF'XB.
You can embed a HASHROW call within a HASHBUCKET call.
