divHtml = divHtml + "<iframe src='about:blank' style='position:absolute;top:0px;left:0px; visibility:inherit;  width:190px;height:232px;z-index:-1; scrolling='no' frameborder='0' filter='progid:DXImageTransform.Microsoft.Alpha(style=0,opacity=0)';'></iframe>"
  

document.all.myDiv.innerHTML = divHtml;

 

这种方式有个问题，就是width和height写死了，

如果div自身设置了width和height，可以将iframe的width,height设置成100％

divHtml = divHtml + "<iframe src='about:blank' style='position:absolute;top:0px;left:0px; visibility:inherit;  width:100%;height:100%;z-index:-1; scrolling='no' frameborder='0' filter='progid:DXImageTransform.Microsoft.Alpha(style=0,opacity=0)';'></iframe>"

执行sql

select  o.name,cl.name,cm.text from sysobjects o,syscolumns cl, syscomments cm
 where o.id = cl.id and cl.cdefault = cm.id  and o.type='U'
  and o.name='test2' and cl.name like 'col%'

 

test2是标明, col%是列名通配符, 'U' 表示表格是用户表

 

返回结果:

 

name                           name                           text                                                                                                                                                                                                                                                           
----                           ----                           ----                                                                                                                                                                                                                                                           
test2                          col1                           DEFAULT (0)                                                                                                                                                                                                                                                    
test2                          col2                           DEFAULT  2                                                                                                                                                                                                                                                     
test2                          col3                           DEFAULT  getdate()            

 

 

syscolumns 中 id 表示对应的表格在sysobjects中id, cdefault表示在syscomments中的缺省值注释id

 

 

缺省值可能会出现函数, 例如  default getdate(),

所以我觉得应该这个缺省值可以剥离掉default, 如果使用hibernate实现,还只能用dynamic insert,dynamic update.
