  /**
   * 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
   * db.update(cars).set({ color: 'red' })
   *   .where(eq(cars.color, 'green'));
   * // or
   * 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
   * 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
   * db.update(cars).set({ color: 'red' })
   *   .where(or(eq(cars.color, 'green'), eq(cars.color, 'blue')));
   * ```
