What should you do if you want to use the data from a single query in multiple places on an interface?

When you want to use data from a single query in multiple places on an interface, the best approach is to store and reference that data using a local variable. This method allows you to execute the query once and then reuse the data throughout the interface wherever needed.

By storing the results of the query in a local variable, you enhance performance since the query will only be executed one time, reducing the load on the server and speeding up the interface response. Additionally, using a local variable helps keep the code organized and maintainable, as you can easily refer to the same data without needing to repeat the query logic.

Other methods, such as creating a separate interface for each usage, would lead to unnecessary redundancy and maintenance challenges, while copying the query multiple times could lead to performance issues and data inconsistency if changes are needed later. Utilizing global variables can also share data, but it increases the complexity of data management and state handling compared to the simplicity and clarity of local variables. Thus, storing and referencing data in a local variable is the most efficient and effective way to manage data usage in your interface.
