String sql = "INSERT INTO HRDF_PATCH(PK_HRDF_PATCH,PATCH_PROVINCE,FUNC_DESCRIPTION,TS,PATCH_DEVELOPERS,QUESTIONS_USE_PATCH,PATCH_INSTRUCTION) VALUES("+patchno+","+appprov+","+describe+","+apptime+","+developer+","+questionno+","+instruction+")";
//ResultSet rs = null;
try {
conn = DBConnection.getConnection();
stmt = conn.createStatement();
//执行增加记录操作：
stmt.executeUpdate(sql);
conn.commit();
}catch(Exception e){e.printStackTrace();}
finally{
if(stmt!=null) stmt.close();
if(conn!=null) conn.close();
}
程序能运行，但就是插不进数据，也不报异常，各位大侠，这是为什么啊？小弟求教了。
在stmt.executeUpdate(sql);处设个断点，debug一下
是不是字符编码问题，或者可能是主键值冲突
