Question

All my entities can not be deleted – only deactivated, so they don’t appear in any read methods (SELECT ... WHERE active=TRUE).

Now I have some 1:M tables on this entities on which all CRUD operations can be executed.

What is more efficient or has better performance?

My first solution: To add to all CRUD operations:

UPDATE ... JOIN entity e ... WHERE e.active=TRUE

My second solution: Before all CRUD operations check if entity is active:

if (getEntity(someId) != null) {
    //do some CRUD
}

In getEntity there’s just SELECT * FROM entity WHERE id=? AND active=TRUE.

Or any other solution, recommendation,…?

Answer 1

Second, plus an active second level cache 😉 Chance is that the object already is in memory. Chance is acutally pretty high.
