How It Affects Your App
MySQL 1615 ER_NEED_REPREPARE has a significant impact on an application. It indicates that the query needs to be re-prepared before it can be executed. This can cause delays in the application as the query needs to be re-prepared and re-executed. It can also lead to unexpected results if the query is not re-prepared correctly. This can lead to data integrity issues and incorrect results. Therefore, it is important to ensure that the query is re-prepared correctly and that the application is able to handle the delay caused by the re-preparation.
