Question

我不知道为什么我会收到语法错误，根据this question一切都应该没问题。我找不到一种方法来执行window function（postgres查询返回多列 GROUPED BY 个人列），这就是我使用原始SQL的原因

我仍然是Postgres的新手，但我认为它可能与消毒有关，但我也不知道如何去做。任何帮助将不胜感激，这是我的代码：

module TasksTestQuery

  def self.call

    query = "SELECT user_id, username, date, SUM(user_id) AS total_work, SUM(duration) AS total_duration OVER (PARTITION BY user_id) FROM tasks"

    ActiveRecord::Base.connection.find_by_sql(query)

  end
end

我得到的确切错误是：

ActiveRecord::StatementInvalid
PG::SyntaxError: ERROR: syntax error at or near "(" LINE 1: SELECT user_id, username, date, SUM(user_id) AS total_work, SUM(duration) AS total_duration OVER (PARTITION BY user_id) FROM tasks

应该是

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<form id="myform" action="https://stackoverflow.com/users/8084795/rohit-bhati" method="POST">
</form>
<select name="tab" form="myform">
  <option value="">Select Tab</option>
  <option value="profile">profile</option>
  <option value="topactivity">activity</option>
</select>

使用原始SQL SELECT命令时出现语法错误
