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