How It Affects Your App
MySQL 1345 ER_VIEW_NO_EXPLAIN has an impact on the application by preventing it from using the EXPLAIN statement to obtain information about the query execution plan. This can lead to inefficient query execution and poor performance. It can also lead to unexpected results due to the lack of information about the query execution plan. This can cause the application to be unreliable and difficult to debug.
