Hi
Since recently (and this is good), when renaming a column Studio generates 2 scripts
- renaming column to column_UNUSED
- drop column_UNUSED
First, it could be useful to notify user that (s)he has to choose between the two. Especially when the drop script is generated before the rename (screenshot below, and if I understand correctly that the order of presenting is the order of execution).
But more important, if column named changed without changing type (and column is not involved in a relation which can be tricky) a simple alter table rename could be generated.
In our case, we renamed “created objects” to “processed objects”, new name reflects change of semantic but the column is of same type and not involved in a fk.
