获取错误，Mysql2 ::错误：你的SQL语法在rails中有错误？

Question

以下查询需要改变什么？我希望所有那些date_of_leaving为空或date_of_leaving在过去60天之间或date_of_leaving大于或等于Date.today或当前日期的员工。

employees = @company.employees.where('date_of_leaving BETWEEN ? AND ? OR date_of_leaving IS NULL OR date_of_leaving IS >= Date.today', Date.today - 60, Date.today) 

我以另一种方式尝试，如下图所示。

employees = Company.find(4).employees.where('date_of_leaving BETWEEN ? AND ? OR date_of_leaving IS NULL OR date_of_leaving IS >= ?', Date.today - 60, Date.today,Date.today) 

Answer 1

我觉得你的问题是短语IS >=。

您不应该使用is与比较运算符。只是运营商。拿出来，否则它看起来不错。
