'How to avoid updating child table when data is null or blank?
I have entity parent in which I am using @SecondoryTable. Secondary table have one info as attribute. Now when I save parent, child is saving automatically.
But I don't want to save child if child data is null. I want to save parent but not child in that case. Which annotation should I use to fixed this in entity?
Solution 1:[1]
That's not possible.
If you want to have the relation optional you must use a @OneToOne relationship instead.
Solution 2:[2]
We can achieve this by using below approach.
In your parent entity where you have defined @SecondoryTable there you have suppose child column so during parent save you need to set the null value in parent for that child attribute.
