IF 语句

You are viewing an old version of this article. View the current version here.

语法结构：

IF search_condition THEN statement_list
    [ELSEIF search_condition THEN statement_list] ...
    [ELSE statement_list]
END IF

解释说明

if语句实现基本的条件判断功能。如果search_condition判断为真，将执行对应的statement_list部分。如果没有条件符合，最后将执行ELSE部分。每个statement_list都由一个或者多个语句组成。

注意: IF() 函数不同于IF语句。
