The remove command executes the following SQL query (KVSTORE.cs:63-66):
DELETE FROM storeWHERE key = $key
The full implementation (KVSTORE.cs:60-71):
public int Remove(string key){ using var command = connection.CreateCommand(); command.CommandText = """ DELETE FROM store WHERE key = $key """; command.Parameters.AddWithValue("$key", key); command.ExecuteNonQuery(); Console.WriteLine($"Removing key: key {key} from vault"); return 0;}
Idempotent OperationThe remove command is idempotent - you can safely run it multiple times on the same key without error. The command does NOT check whether the key exists before attempting deletion.The same success message is displayed regardless of whether the key was found:
Removing key: key mykey from vault
If you need to verify whether a key existed before removal, use get first.
No ConfirmationThe remove command does not ask for confirmation before deleting. Once executed, the key-value pair is permanently removed from the vault.Make sure you want to delete the key before running this command!
