We are ready to deploy our instance to production and I'm currently cleaning all the demo data made during the process.

I usually follow this steps to clean major sample data:

*SSH into server*

```
su postgres
psql abc_db_name

delete from stock_pack_operation;
delete from stock_picking;
delete from stock_move;
delete from account_invoice;
delete from account_partial_reconcile;
delete from account_move;
delete from sale_order;
delete from account_payment;

```

**The main problem I'm facing now is set all the product quantities to 0 without deleting the products.** What's the query I need to run to set this to reset them and start the inventory from scratch?
