/**
* Adds a `where` clause to the query.
*
* Calling this method will delete only those rows that fulfill a specified condition.
*
* See docs: {@link https://orm.drizzle.team/docs/delete}
*
* @param where the `where` clause.
*
* @example
* You can use conditional operators and `sql function` to filter the rows to be deleted.
*
* ```ts
* // Delete all cars with green color
* db.delete(cars).where(eq(cars.color, 'green'));
* // or
* db.delete(cars).where(sql`${cars.color} = 'green'`)
* ```
*
* You can logically combine conditional operators with `and()` and `or()` operators:
*
* ```ts
* // Delete all BMW cars with a green color
* db.delete(cars).where(and(eq(cars.color, 'green'), eq(cars.brand, 'BMW')));
*
* // Delete all cars with the green or blue color
* db.delete(cars).where(or(eq(cars.color, 'green'), eq(cars.color, 'blue')));
* ```
