Question

将数据放在同一行时遇到问题。

这是我的界面显示：

数据库：

我想创建一个如果用户同时分配腿部和手臂运动的地方，数据库将在一行中显示腿部和手臂运动。但是现在当我将它们都插入在一起时，数据库中的数据将位于两个不同的行中。

.js代码

    String[] id = request.getParameterValues("assignchkbox");
    String armID = request.getParameter("ArmID");
    String armnumber    = request.getParameter("Armnumber");
    int count=0;
    Connection conn = null;
    try {
        Class.forName("com.mysql.jdbc.Driver");
        // Step 2: Define Connection URL
        String connURL = "jdbc:mysql://localhost/medicloud?user=root&password=root";
        // Step 3: Establish connection to URL
        conn = DriverManager.getConnection(connURL);

        if (id != null)
        {
