Hello, my friends!
I have a table called Animals, where I have record cattle information. When cow calved, I have added a new row with information new bord calve.
Every cow row has a column called mother. So, when I record newborn calve I have just added mother ID to the mother column.
Now, I want to see all the calves of cow in a detailed view.
How can I select calves from the Animals table in virtual column ?
