IDEA连接数据库报错
报错代码:Data truncation: Cannot get geometry object from data you send to the GEOMETRY field给我定位到了这一行代码:
int result = statement.executeUpdate(sql);
然后源码如下,也不多:
public class Test {
public static void main(String[] args) {
//加载驱动
try {
Class.forName("com.mysql.cj.jdbc.Driver");
//获取连接
String url = "jdbc:mysql://localhost:3306/test?useSSL=false&serverTimezone=GMT%2B8";
String user = "root";
String password = "123456";
try {
Connection connection = DriverManager.getConnection(url,user,password);
String sql = "insert into student_table(username,age) values('zhangSan','7')";
Statement statement = connection.createStatement();
int result = statement.executeUpdate(sql);
System.out.println(result);
} catch (SQLException throwables) {
throwables.printStackTrace();
}
} catch (ClassNotFoundException e) {
e.printStackTrace();
}
}
}
我的数据库中test下只有一个表student_table,只有三项内容:id,username和age;username的数据类型是lineString,这样写sql语句应该没问题吧。 数据截断:无法从发送到“几何体”字段的数据中获取几何体对象
