I have a column in my database table where the default needs to be ‘int 0’ but also null can be provided due to legacy.
I have attached a picture to show what I am trying to do.
The problem I am having is that when I untick ‘Not Null’ and have a default of 0, and a null value is provided then null is added.
But if I tick the box and null is provided it does not add 0, my code throws an exception instead stating the value for this column must not be null.
I want it do that if null is provided then it defaults to 0.
Appreciate any help on this. Thanks
Note: I am using Datagrip
I am assuming something in ‘default expression’ but I am not sure what

Check Data on controller before sending it to database
You could create a BEFORE INSERT trigger:
More information on triggers can be found in the documentation.
