What is the primary use of the "Where" function in queries?

The primary use of the "Where" function in queries is to filter entries based on a condition, allowing users to narrow down results according to specified criteria. When you implement the "Where" function, it evaluates each entry in the dataset and returns only those that meet the stated conditions. This is essential in database querying, as it enables more precise and efficient data retrieval, ensuring that users can focus on relevant information without wading through unnecessary data.

For example, if a database contains customer records and you want to find all customers located in a specific city, the "Where" function can be used to filter out the entries to only display those that meet this geographical condition. This filtering capability is vital for analyzing datasets effectively and is a fundamental aspect of data querying in systems like Guidewire.
