How to alter column by using JPA? I would like to change column or the type of the column in a exsiting schema. In persitence page, there are only update or create.
If I mondified my entity class for example change the column name and choose update, it would just add a new column to me instead of change the column name. And if I change type of a column, nothing will be generated.
If I mondified my entity class and choose create, it will drop my table which I don't want it cause I would like to keep all my data.
Is there suggestion to achieve that? Thank you for your time.
