Question: I have a table like below

```
Order_Id (PK), Customer_ID, Order_Amount
  A01             AA01         100
  A01             AA01         100 (duplicate)
  A02             AA01         200
  A03             AA02         300

```

I want to remove the duplicate and retain the remaining one

I'm able to select the duplicate using below

```
select *
from 
(
select order_id, customer_id, order_amount, row_number () over (partition by order_id order by order_Id) as rnk
from mytable
) where rnk > 1

```

But what's the next step to delete this record from mytable? Do I need to create a interim table?

Thanks!

Answer: 
You can specify the `--source-map=false` attribute for Angular to load only the stuff that it needs, and will recompile only those parts of your application, that have been modified.

```
ng serve --source-map=false

```

In my case (Angular v.11), `ng serve` takes about 1 minute to serve the app, but the `ng-serve --source-map=false` takes somewhere from 10 to 30 seconds. Moreover, changes are applied much more faster.
Use the --verbose option to see what's going wrong behind the scenes:

```
ng serve --verbose

```
