Can You Trigger MySQL Actions on SELECT Statements?

Triggering MySQL Actions on SELECT Statements

Can you trigger a MySQL action, such as an INSERT statement, when a SELECT query is executed on a specific table? The answer is typically no, as MySQL triggers are predominantly associated with INSERT, UPDATE, or DELETE operations.

Alternative Solution

However, there is a potential workaround for this unique scenario:

1. Create Stored Procedures for SELECTs:

   • Define stored procedures that encapsulate the SELECT statements you intend to execute on table X.

2. Restrict Direct SELECT Access:

   • Limit user privileges to prevent direct SELECT queries on table X. Instead, enforce the use of the aforementioned stored procedures.

3. Modify Stored Procedures:

   • Alter the stored procedures to integrate a call to an additional stored procedure that carries out the desired action (e.g., INSERT).

By employing this approach, you can essentially simulate the behavior of a trigger that responds to SELECT statements. However, it's important to note that this solution involves modifying the query execution flow and may require careful considerations and cautious implementation.
