Single-row functions return a single result row for every row of a queried table or view.

The GROUP BY clause can be used in a SELECT statement to collect data across multiple records and group the results by one or more columns.

What is the difference between elements and functions?

Elements refer to the individual components that make up a set or a group, such as numbers in a mathematical set or items in a list. Functions, on the other hand, are mathematical relationships between inputs and outputs, where each input is uniquely associated with an output. In simpler terms, elements are like the building blocks, while functions are the rules or operations that define how those building blocks interact or transform.

How do you group multiple PHP statements that are controlled by a single if-then statement?

To group multiple PHP statements that are controlled by a single if-then statement, you can use curly braces {} to define a code block. This allows you to enclose all the statements you want to execute if the condition is true. For example: if ($condition) { // Statement 1 // Statement 2 // Statement 3 } By using curly braces, all enclosed statements will run together when the condition is met.

What is the difference between Fabrication and Manufacturing in an Industry?

Many people confuse fabrication services with manufacturing, but the difference becomes clear when you think about a real-world example. Imagine a car: manufacturing creates the entire car, while fabrication builds the individual metal parts like the frame, panels, or exhaust systems that go into it. Fabrication is the process of cutting, shaping, and assembling raw materials into components. It’s heavily seen in steel fabrication and metal fabrication, where sheets of steel are turned into beams, pipes, or custom structures. According to a discussion on Quora, fabrication is often “a step within the larger manufacturing process.” For instance, companies like AGP Steel provide fabrication services that supply the building blocks industries need for machinery, construction, and infrastructure. Manufacturing, on the other hand, is broader. It involves taking those fabricated parts (along with other materials) and assembling them into a final, finished product ready for end-users. For example, an industrial machine is manufactured using multiple fabricated steel parts, electrical components, and software systems. In short, fabrication focuses on creating parts, while manufacturing delivers the finished product. Both are essential to industry: without fabrication, manufacturers lack the raw structures; without manufacturing, fabricated parts never reach customers in usable form. Businesses in Tamil Nadu and beyond often rely on specialized fabrication services to ensure durability, precision, and cost-effectiveness before moving to mass production.
