The coalesce function provides one way to substitute constant values for _________________ values.
The coalesce function provides one way to substitute constant values for null values.
What is a coalesce function?Is a function that returns the first non-NULL value from a series of expressions. The expressions are evaluated in the order in which they are specified, and the result of the function is the first value that is not null. The result of the COALESCE function returns NULL only if all the arguments are null.
Data type determination of the resulting expression is different. ISNULL uses the data type of the first parameter, COALESCE follows the CASE expression rules and returns the data type of value with the highest precedence.

Geometric representation of how the computers are connected to each other is known as topology. There are five types of topology.
They are,
Bus topologyRing topologyStar topologyMesh topologyTree topology ♻Bus topologyBus topology, also known as line topology, is a type of network topology in which all devices in the network are connected by one central RJ-45 network cable or coaxial cable. The single cable, where all data is transmitted between devices, is referred to as the bus, backbone, or trunk.
♻Ring topologyRing topology is a type of network topology in which each device is connected to two other devices on either side via an RJ-45 cable or coaxial cable. This forms a circular ring of connected devices which gives it its name. Data is commonly transferred in one direction along the ring, known as a unidirectional ring.
♻Star topologyStar topology is an implementation of a spoke–hub distribution paradigm in computer networks. In a star network, every host is connected to a central hub. In its simplest form, one central hub acts as a conduit to transmit messages. The star topology is one of the most common computer network topologies.
♻Mesh topologyA mesh topology is a network setup where each computer and network device is interconnected with one another. This topology setup allows for most transmissions to be distributed even if one of the connections goes down. It is a topology commonly used for wireless networks.
♻Tree topologyA tree topology is a special type of structure where many connected elements are arranged like the branches of a tree. For example, tree topologies are frequently used to organize the computers in a corporate network, or the information in a database.

how drone technology can impact recreation and entertainment
Drones are become more advanced than ever before. Are now, they are starting to impact recreation. They are small, light, and can maneuver incredibly fast. They are being used in movies, skits, short films, and even high-end videos. Here are some ways drones are changing entertainment:
- Providing high-quality filming, even from 200 feet in the air.
- Reaching spaces where bulky helicopters cannot fit into safely
- Laser shows, where drones shine lights and lasers.
Right now, if you tried to hold your phone still to capture a video, you would not be able to do it. Upon checking the footage, you would see the camera shaking, even if it's just tiny bit. While you can lean it on a surface to fix this, it simply cannot be done in the air to capture. Not to worry, though, you've got drones. They can shoot a steady shot 200 feet in the air. The only thing that could rival drones are expensive, bulky choppers. The drones are cheaper and are mass produced.
