SQL command: WHERE - GCSE Computer Science Definition

The SQL command "WHERE" is used in databases to filter records and select only those that meet certain conditions. Imagine you have a big list of data, like a library with thousands of books, but you only want to see the books written by a certain author. By using the "WHERE" command, you can tell the computer to show only the records that match this specific rule. For example, if you want to find all students who scored more than 70 in their exams from a database, you would use the "WHERE" command to narrow down the list to just those students. It's like using a filter to see only the information you’re interested in from a large set of data.
