Delete command syntax in Google Bigquery

Use the DELETE statement when you want to delete rows from a table

To delete all rows from a table (i.e to truncate a table)

DELETE FROM dataset.DetailedInventory WHERE true;

DELETE with WHERE clause

DELETE FROM dataset.Inventory WHERE quantity = 0;

Alternately, you can use DELETE with the EXISTS clause:

DELETE FROM dataset.Inventory
WHERE NOT EXISTS
(SELECT * from dataset.NewArrivals
WHERE Inventory.product = NewArrivals.product);
