我写了一个程序，用单词列表填充数据库。问题是，每次我尝试运行代码时，它都会引发“线程“ main”中的异常”
java.sql.SQLException：在“ s”附近：语法错误”。我知道在此论坛上也曾提出过类似的问题，但是在我的代码中，我无法纠正该错误。

因此，我求助于您。

这是代码

import java.io.*;
import java.sql.*;
import java.util.Scanner;

public class db_populate {

    public static void main(String[] args) throws SQLException, IOException,
            ClassNotFoundException {
        Connection c = null;
        Statement stmt = null;
        Scanner in = null;
        String word;
        String wordcat;
        String j, sql;
        int i = 0;

        Class.forName("org.sqlite.JDBC");
        c = DriverManager.getConnection("jdbc:sqlite:dictionary.db");
        c.setAutoCommit(false);
        System.out.println("Opened database successfully");

        stmt = c.createStatement();

        in = new Scanner(new File("wordsEn.txt"));

        while (in.hasNext()) {
            word = in.nextLine();
            i++;
            j = Integer.toString(i);
            wordcat = word.substring(0, 2);
            sql = "INSERT INTO WORDS (ID,CAT,WORD) " + "VALUES(" + j + ",'"
                    + wordcat + "','" + word + "');";
            stmt.executeUpdate(sql);
        }

        stmt.close();
        c.commit();
        c.close();
        in.close();
        System.out.println("Records created successfully");
    }

}

这些是我跑步时遇到的错误。
