Update (SQL)
Okay kiddo, let's say you have a toy box with lots of toys in it (imagine each toy as a piece of information in a database). Sometimes, you may want to change something about a toy, like maybe you want to give your toy car a new paint job or add some stickers.
In the same way, people who work with databases sometimes need to change or update information in the database. They use a special code language called SQL (Structured Query Language) to tell the database what they want to do.
So, updating in SQL means that someone is telling the database to change certain information that is stored in it. For example, let's say you have a database of people's ages and you accidentally entered someone's age as 35 instead of 25. You can use SQL to update that person's age from 35 to 25.
It's like giving a toy a makeover – you're changing something about it to make it better or correct a mistake. Updating in SQL can be important because it helps keep the information in a database accurate and up-to-date.
