In Redis, the ZINTER command returns the intersection of the specified sorted sets. In other words, it returns only those members that are present in all sorted sets.
In Redis, the ZDIFFSTORE command computes the difference between the first and all successive input sorted sets and stores the result in the specified key.
ZDIFFSTORE works in the same way as the ZDIFF command, except that it stores the result instead of returning it (ZDIFF returns the result instead of storing it in a new key).
In Redis, the ZDIFF command returns the difference between the first and all successive input sorted sets.
In Redis, the ZCOUNT command returns the number of elements in a sorted set with a score between two given values.
In Redis, the ZRANDMEMBER command enables us to get one or more random elements from a sorted set.
We can specify whether or not to return only distinct elements or to allow duplicates. We can also specify whether or not to include the scores of each element in the result.
In SQL Server we can query the sys.parameters system catalog view to return all parameters that belong to user-defined objects.
For system objects, we can query the sys.system_parameters view. We can alternatively query the sys.all_parameters system catalog view to return all parameters that belong to either user-defined or system objects.
