Can MySQL Triggers be Activated by SELECT Statements?

Can Triggers Be Activated by SELECT Statements in MySQL?

Question:

Can MySQL triggers be utilized to initiate an INSERT operation into table X whenever a select operation is performed on table Y?

Answer:

No, triggers in MySQL are not triggered by SELECT statements.

Alternative Solution:

Despite the absence of triggers for SELECT statements, there is a workaround:

  1. Create stored procedures that perform the desired SELECT operations on table X.
  2. Restrict user access to table X, allowing them to only execute the stored procedures.
  3. Modify the stored procedures to include a subsequent call to a stored procedure that performs the desired INSERT action (or any other desired action).
