ACTION 中 单表查询语句 SQL写法

JSP页面

<tr>
<td class="STYLE1">
<div align="center">

// 单击事件 调用方法

<input type="image" id="imageField22222" name="imageField22222" src="../btn/btn_cx.gif" id="sub" onclick="queryAllEqu();"/>
</div>
</td>
</tr>

<script language="javascript">

// 用于提交 ACTION 
function queryAllEqu(){
document.form.submit();
}
</script>

// 这里写出调用的ACTION 及传送方式

<form action="QueryEquApplianceAllInfo.action" name="form" method="post">

// 这里是写出隐藏域 用来传递code的参数
<input type="hidden" name="code" value="${code }"/>
