Java JDBC插入错误

我正试图用jdbc将一些数据插入我的数据库。我使用的是正确的表、数据库名称和参数。一切都检查过了

代码

public static void main(String[] args) throws IOException/*, ClassNotFoundException, SQLException*/ {
    DataInputStream d = new DataInputStream(System.in);
    System.out.println("Enter employee ID : ");

    @SuppressWarnings("deprecation")
    int empid = Integer.parseInt(d.readLine());

    System.out.println("Enter employee name : ");

    @SuppressWarnings("deprecation")
    String empname = d.readLine();

    System.out.println("Enter employee ID : ");
    @SuppressWarnings("deprecation")
    double empsalary = Double.parseDouble(d.readLine());

    try {
        Class.forName("com.mysql.jdbc.Driver");

    } catch (ClassNotFoundException e) {
        e.printStackTrace();
    }

    Connection con;
    try {
        con = DriverManager.getConnection("jdbc:mysql://localhost:3306/testDB","root","");
        PreparedStatement  pst = con.prepareStatement("insert into `employee` values(?,?,?");
        pst.setInt(1, empid);
        pst.setString(2, empname);
        pst.setDouble(3, empsalary);
        int rowcount = pst.executeUpdate();
        System.out.println(rowcount + " row has been instered");
    } catch (SQLException e) {

        e.printStackTrace();
    }

下面是当我尝试运行它时它给我的错误：

com.mysql.jdbc.exceptions.MySQLSyntaxErrorException: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '' at line 1

values子句中缺少右括号

PreparedStatement  pst = con.prepareStatement("insert into employee values(?,?,?)");

---

此行中出现语法错误：

PreparedStatement  pst = con.prepareStatement("insert into `employee` values(?,?,?");

---

您缺少values子句的右括号。

我从mysql论坛上读到了这一点，没有引号，我也有相同的内容problems@Seekerakos还有缺少的右括号。@Seekerakos主要问题是缺少右括号，但是您通常也指定要插入的列。如果添加了列或表中列的顺序发生变化，您当前的插入将中断。是的，我解决了。Gmartines说同样的话，感谢大家抽出时间！！

PreparedStatement  pst = con.prepareStatement("insert into employee values(?,?,?)");
