The example returns 6. The formula is calculated from left to right as: 1 + 2 equals 3, giving the result to date when CURRENT() is encountered; CURRENT() therefore yields 3, which is added to the original 3 to give 6.
该示例返回 6。公式从左到右计算：1 + 2 等于 3，这是遇到 CURRENT() 时得到的结果；因此 CURRENT() 为 3，加上最初的 3 后得到 6。
