Sql Server获取数据库字段名，并用list显示在jsp页面

Sql Server查询数据库表字段名

SELECT NAME FROM SysColumns WHERE ID = OBJECT_ID('tableName')

 查询并将结果存入list中

String columnName = "SELECT NAME FROM SysColumns WHERE ID = OBJECT_ID('tableName')";
List<Map<String,Object>> columnNameList = daoJdbc.findListBySql(columnName);
request.setAttribute("columnNameList", columnNameList);

在jsp页面遍历输出字段名

<s:iterator value="#request.columnNameList" var="nameMap">
    <s:iterator value="nameMap">
     　　<td width="${fn:length(value)*20}">${value}</td>
    </s:iterator>
</s:iterator>
