I have table A in Oracle that has a primary key (id). I need to insert data into this table.
How do I prevent duplicate rows?
If the id column is marked as the PK you will not be able to insert a duplicate key, the server will throw an exception.
If you will insert duplicate data with different key – that’s a logic that you need to deal with (like putting a unique constraint on the actual data) or do a check before you insert.
