编译错误 "cannot find symbol"

Question

我正在尝试将数据插入 MySQL，但出现错误：

cannot find symbol c

import java.sql.*;

class Insert{

    public static void main(String args[]){
        try{
            Class.forName("com.jdbc.mysql.Driver");
            Connection c = DriverManager.getConnection("jdbc:mysql://localhost:3036/db","ravi","ravi");
            //showing error in the below statement at c
            Statement stmt = c.CreateStatement();
            int result=stmt.executeUpdate("Insert into emp values(3,'david',33) ");
            System.out.println("success");
            c.close();
        } catch(Exception e) {
            System.out.println(e);
        }
    }

}

Answer 1

是 c.createStatement() 而不是 c.CreateStatement()。

您需要将方法名称中的 c 设为小写 createStatement()
