2、错误原因

public static void insertStudent()
{
StringBuffer sql = new StringBuffer();
int j = 0;
String str = "0";
for(int i=5;i<1000;i++)
{
++j;
if(i%2 == 0)
{
str = "0";
}
else
{
str = "1";
}
sql.append("insert into t_stu_info (").append(i).append(",").append(103+j+"").append(",")
.append("zhangsan"+(i-4)).append(",").append(str).append(",")
.append(Integer.parseInt(Math.round(Math.random()*10+20)+"")).append(",")
.append("123"+i);
}

commonMethod(sql.toString());
}

/**

* @Title:Student
* @Description:

* @return :void

*/
public static void commonMethod(String sqlStu)
{
StringBuffer sql = new StringBuffer();
sql.append(sqlStu);
Connection conn = null;
Statement stat = null;
ResultSet rs = null;
try
{
try
{
Class.forName(DRIVER_CLASS);
}
catch (ClassNotFoundException e)
{
e.printStackTrace();
}
conn = DriverManager.getConnection(URL, USER, PASSWORD);
stat = conn.createStatement();
rs = stat.executeQuery(sql.toString());
while(rs.next())
{
String stuId = rs.getString("stu_id");
String stuName = rs.getString("stu_name");
String stuSex = rs.getString("sex");
String stuAge = rs.getString("stu_age");
String stuPhone = rs.getString("stu_phone");
System.out.println("学号："+stuId+"----"+"姓名："+stuName+"----"+"性别："+stuSex+"---"+"年龄："+stuAge+"----"+"电话："+stuPhone);
}
}
catch (SQLException e)
{
e.printStackTrace();
}
finally
{
if(rs != null)
{
try
{
rs.close();
}
catch (SQLException e)
{
e.printStackTrace();
}
}
if(stat != null)
{
try
{
stat.close();
}
catch (SQLException e)
{
e.printStackTrace();
}
}
if(conn != null)
{
try
{
conn.close();
}
catch (SQLException e)
{
e.printStackTrace();
}
}
}
}

3、解决办法

由于在执行插入操作时，调用了executeQuery方法，出现错误；插入操作应该调用executeUpdate方法

int result = stat.executeUpdate(sql.toString());
