Ticket #735 (closed defect: fixed)
Altering a column does not remove UNIQUE constraint
|Reported by:||Stephan Jaensch <sj@…>||Owned by:||andrew|
Using the Oracle backend, I have a migration modifying a column that has a UNIQUE constraint. The new column definition in the alter_column() call does not specify unique=True, but the constraint is not actually dropped.
Note that the other way around works just fine, namely altering a column and adding a UNIQUE constraint to it.
