How It Affects Your App

This error can have a significant impact on an application as it prevents any further queries from being executed. This can lead to a disruption in the application's functionality, as it is unable to access the necessary data. Additionally, the application may become unresponsive or slow down significantly, as it is unable to process the queries. This can lead to a decrease in user satisfaction and a decrease in productivity.
