Mysql这问题还是不能解决,非连接问题!!!
源代码“
import java.sql.Connection;
import java.sql.PreparedStatement;
import java.sql.DriverManager;
import java.sql.SQLException;
import java.io.File;
import java.io.FileInputStream;
import java.io.InputStream;
public class BlobDemo1{
private static final String Driver="org.gjt.mm.mysql.Driver";
private static final String dburl="jdbc:mysql://localhost:3306/justhin";
private static final String user="root";
private static final String password="admin";
public static void main(String args[]) throws Exception{
Connection con=null;
PreparedStatement psmt=null;
// ResultSet rs=null;
String name="平南";
String sql="insert into blob1(name,movies) values(?,?)";
Class.forName(Driver);
con=DriverManager.getConnection(dburl,user,password);
psmt=con.prepareStatement(sql);
File f=new File("F:"+File.separator+"20110821482.jpg");
InputStream input=null;
input=new FileInputStream(f);
psmt.setString(1,name);
psmt.setBinaryStream(2,input,(int)f.length());
psmt.executeUpdate();
input.close();
psmt.close();
con.close();
}
}运行报错:

数据库:
mysql> desc blob1;
+--------+-------------+------+-----+---------+----------------+
| Field | Type | Null | Key | Default | Extra |
+--------+-------------+------+-----+---------+----------------+
| id | int(11) | NO | PRI | NULL | auto_increment |
| name | varchar(30) | NO | | | |
| movies | longblob | YES | | NULL | |
+--------+-------------+------+-----+---------+----------------+
----------------解决方案--------------------------------------------------------
这个问题我也看不懂
----------------解决方案--------------------------------------------------------
id是没有加。。。
----------------解决方案--------------------------------------------------------
你把表重新建下。。确定加上 auto_increment
才能省略不加id
----------------解决方案--------------------------------------------------------
这货不是代码、把能删的都删了,剩下最简单的连接数据库的四步看看行不行,如果不行就是数据库的问题了
----------------解决方案--------------------------------------------------------
Exception in thread "main" com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorExce
看清楚异常MySQLSyntaxErrorExce
mysql语法错误
