In SQL, which keyword is used to give an alias to a computed column, such as labeling the result as product_ID?

Labeling a computed column in SQL requires giving a name to the result of an expression so you can reference it in the rest of the query or in the output. The keyword AS provides that alias in the canonical syntax, as in SELECT price * quantity AS product_ID FROM products. The other options don’t fit: FROM specifies the source table; ASNAME isn’t a SQL keyword; ALIAS isn’t used as the standard keyword for aliasing.
