安装后找不到Common_schema函数get_option

Question

所以我已经将common_schema安装到我的mysql服务器上，并尝试使用get_option函数执行操作。

我的SQL：

SELECT *, ((get_option("program_invested_details", "received") * 100) / get_option("program_invested_details", "invested")) AS PERCENT_TOTAL FROM hp_programs_list WHERE program_add_status = 4 AND program_status = 1 ORDER BY PERCENT_TOTAL DESC

但似乎get_option函数不起作用，因为我收到了这个错误：

  

功能hyips_database.get_option不存在

我的数据库结构：
