我无法让jQuery 3.1.0与jQuery UI的自动完成功能一起使用.

我所知道的唯一解决方法是将jQuery 3.1.0替换为使用jquERY UI安装程序预先打包的那个.不幸的是,这对我不起作用,因为jQuery UI的安装程序包中的版本不允许我使用我的网站所需的标签输入和其他现代功能.

<input type="email" id="tags" class="form-control" placeholder="Any Criteria" data-role="tagsinput">

<script type="text/javascript" src="external/jquery/js/jquery-3.1.0.min.js"></script>
<script type="text/javascript" src="external/jquery-ui/js/jquery-ui.min.js"></script>
  <script>
      $( function() {
        var availableTags = [
          "ActionScript",
          "AppleScript",
          "Asp",
          "BASIC",
          "C",
          "C++",
          "Clojure",
          "COBOL",
          "ColdFusion",
          "Erlang",
          "Fortran",
          "Groovy",
          "Haskell",
          "Java",
          "JavaScript",
          "Lisp",
          "Perl",
          "PHP",
          "Python",
          "Ruby",
          "Scala",
          "Scheme"
        ];
        $( "#tags" ).autocomplete({
          source: availableTags
        });
      } );

是否可以在Where子句中使用Rank.以下是我打算使用的代码

  Select 
   DebtorID
  ,Rank () over (partition by DebtorID order by BalanceDate) as RankBalanceDate
  ,BalanceDate
  ,Balance
  ,UnallocatedBalance
  ,Overdue
From Debtorbalances
Where Rank () Over (Partition by DebtorID order by BalanceDate) = 1

在python 3中，以下代码集有效，我想知道为什么在python 2.7中它给我TypeError：必须以calc实例作为第一个参数（而不是int实例）调用未绑定方法add（）？如何在Python 2.7中解决此问题？

class calc:
    def add(x,y):
        answer = x + y
        print(answer)

    def sub(x,y):
        answer = x - y
        print(answer)

    def mult(x,y):
        answer = x * y
        print(answer)

    def div(x,y):
        answer = x / y
        print(answer)

calc.add(5, 7)

我有两个表的以下设计，我无法使用 NATURAL JOIN 连接来测试参照完整性。它适用于 INNER JOIN，但不适用于 NATURAL JOIN ：

表 1. 项目

        DROP TABLE IF EXISTS Project CASCADE;
        CREATE TABLE Project (
                ProjectKey CHAR(10)
                ,ProjectName VARCHAR(255)
                ,ProjectType CHAR(20)
                ,URL VARCHAR
                ,ProjectLeadUsername VARCHAR(255) NOT NULL
                ,ProjectLeadGroupName VARCHAR(255) NOT NULL
                ,DefaultAssignee CHAR(50)
                ,ProjectCategory VARCHAR(255) NULL
                ,Description TEXT
                ,PermissionSchemeKey CHAR(10)
                ,IssueTypeSchemeKey CHAR(20)
                ,WorkflowSchemeKey CHAR(20)

            ,CONSTRAINT Project_PK PRIMARY KEY (ProjectKey)

            ,CONSTRAINT Project_FK_PermissionScheme FOREIGN KEY (PermissionSchemeKey) REFERENCES PermissionScheme
                ON DELETE RESTRICT
                ON UPDATE CASCADE

            ,CONSTRAINT Project_FK_IssueTypeScheme FOREIGN KEY (IssueTypeSchemeKey) REFERENCES IssueTypeScheme
                ON DELETE RESTRICT
                ON …
