<span><code>JoinRowSet</code>接口提供了将不同<code>RowSet</code>对象的相关数据<code>RowSet</code>到一个<code>JoinRowSet</code>对象中的机制，该对象表示SQL <code>JOIN</code> 。</span>
<span>换句话说， <code>JoinRowSet</code>对象充当来自<code>RowSet</code>对象的<code>RowSet</code> ，形成一个SQL <code>JOIN</code>关系。</span>
<p> <span><code>Joinable</code>接口提供了设置，检索和取消设置匹配列的方法，建立SQL <code>JOIN</code>关系的基础。</span> <span>可以通过将匹配列提供给<code>JointRowSet</code>方法<code>addRowSet</code>的适当版本来设置匹配列。</span> </p>
<h3> <span>1.0概述</span> </h3>
<span>断开<code>RowSet</code>对象（ <code>CachedRowSet</code>对象和扩展的实现<code>CachedRowSet</code>接口）没有标准的方法来建立一个SQL <code>JOIN</code>之间<code>RowSet</code>对象，而不重新连接到数据源的昂贵的操作。</span>
<span><code>JoinRowSet</code>接口专门用于满足这一需求。</span>
<p> <span>任何<code>RowSet</code>对象都可以添加到<code>JoinRowSet</code>对象中，成为SQL <code>JOIN</code>关系的一部分。</span> <span>这意味着连接和断开的<code>RowSet</code>对象可以是<code>JOIN</code>一部分。</span> <span><code>RowSet</code>在连接环境中（操作对象<code>JdbcRowSet</code>对象）鼓励使用数据库它们已经连接到SQL建立<code>JOIN</code>直接表之间的关系。</span> <span>但是，如果需要，可以将<code>JdbcRowSet</code>对象添加到<code>JoinRowSet</code>对象。</span> </p>
<p> <span>任何数量的<code>RowSet</code>对象都可以添加到<code>JoinRowSet</code>的实例中，前提是它们可以在SQL <code>JOIN</code>相关。</span> <span>根据定义，SQL <code>JOIN</code>语句用于根据公共属性组合包含在两个或多个关系数据库表中的数据。</span> <span><code>Joinable</code>接口提供了建立公共属性的方法，通过设置<i>匹配列</i>来完成。</span> <span>匹配列通常与主键一致，但不要求匹配列与主键相同。</span> <span>通过建立和实施再列匹配，一个<code>JoinRowSet</code>对象建立<code>JOIN</code>之间的关系<code>RowSet</code>没有可用的关系数据库的援助对象。</span> </p>
<p> <span>的类型的<code>JOIN</code>要建立是通过将所确定<code>JoinRowSet</code>使用该方法的常量<code>setJoinType</code> 。</span> <span>可以设置以下SQL <code>JOIN</code>类型：</span> </p>
<ul>
<li> <code>CROSS_JOIN</code> </li>
<li> <code>FULL_JOIN</code> </li>
<li> <span><code>INNER_JOIN</code> - 如果没有设置<code>JOIN</code>类型的默认值</span> </li>
<li> <code>LEFT_OUTER_JOIN</code> </li>
<li> <code>RIGHT_OUTER_JOIN</code> </li>
</ul>
<span>请注意，如果没有设置类型， <code>JOIN</code>将自动成为内部连接。</span>
<span>对<code>JoinRowSet</code>界面中的字段的<code>JoinRowSet</code>解释了这些<code>JOIN</code>类型，这是标准的SQL <code>JOIN</code>类型。</span>
<h3> <span>2.0使用<code>JoinRowSet</code>对象创建<code>JOIN</code></span> </h3>
<span>当创建<code>JoinRowSet</code>对象时，它为空。</span>
<span>要添加的第一个<code>RowSet</code>对象成为<code>JOIN</code>关系的基础。</span>
<span>应用程序必须确定要添加到<code>JoinRowSet</code>对象的每个<code>RowSet</code>对象中的哪个列应该是匹配列。</span>
<span>所有<code>RowSet</code>对象必须包含匹配列，每个匹配列中的值必须是可与其他匹配列中的值进行比较的值。</span>
<span>列不必具有相同的名称，尽管它们经常做到，并且只要可以比较数据类型，它们就不必存储完全相同的数据类型。</span>
<p> <span>匹配列可以通过两种方式设置：</span> </p>
<ul>
<li> <span>通过调用<code>Joinable</code>方法<code>setMatchColumn</code></span> <br/> <span>这是在将<code>RowSet</code>对象添加到<code>JoinRowSet</code>对象之前可以设置匹配列的唯一方法。</span> <span><code>RowSet</code>对象必须实现<code>Joinable</code>接口才能使用方法<code>setMatchColumn</code> 。</span> <span>一旦设置了匹配列值，该方法就可以随时重置匹配列。</span> </li>
<li> <span>通过调用<code>JoinRowSet</code>方法<code>addRowSet</code>一个版本，该方法采用列名或数字（或列名或数字数组）</span> <br/> <span>五个<code>addRowSet</code>方法中的四个将匹配列作为参数。</span> <span>这四种方法设置或在时间复位的匹配列<code>RowSet</code>对象被添加到一个<code>JoinRowSet</code>对象。</span> </li>
</ul>
<h3> <span>3.0示例使用</span> </h3>
<p> <span>以下代码段将两个<code>CachedRowSet</code>对象添加到<code>JoinRowSet</code>对象。</span> <span>请注意，在此示例中，没有设置SQL <code>JOIN</code>类型，因此默认的<code>JOIN</code>类型（即<i>INNER_JOIN</i> ）已建立。</span> </p>
<p> <span>在以下代码片段中，将匹配列设置为第一列（ <code>EMP_ID</code> ）的表<code>EMPLOYEES</code>添加到<code>JoinRowSet</code>对象<i>jrs</i> 。</span> <span>然后添加表<code>ESSP_BONUS_PLAN</code> ，其匹配列同样为<code>EMP_ID</code>列。</span> <span>当该第二表被添加到<i>JRS，</i>只有在排<code>ESSP_BONUS_PLAN</code>其<code>EMP_ID</code>值相匹配的<code>EMP_ID</code>在值<code>EMPLOYEES</code>加入表中。</span> <span>在这种情况下，奖金计划中的每个人都是员工，所以表<code>ESSP_BONUS_PLAN</code>中的所有行都添加到<code>JoinRowSet</code>对象中。</span> <span>在此示例中，正在添加的<code>CachedRowSet</code>对象已实现<code>Joinable</code>接口，因此可以调用<code>Joinable</code>方法<code>setMatchColumn</code> 。</span> </p>
<pre>  <span>JoinRowSet jrs = new JoinRowSetImpl();

     ResultSet rs1 = stmt.executeQuery("SELECT * FROM EMPLOYEES");
     CachedRowSet empl = new CachedRowSetImpl();
     empl.populate(rs1);
     empl.setMatchColumn(1);
     jrs.addRowSet(empl);

     ResultSet rs2 = stmt.executeQuery("SELECT * FROM ESSP_BONUS_PLAN");
     CachedRowSet bonus = new CachedRowSetImpl();
     bonus.populate(rs2);
     bonus.setMatchColumn(1); // EMP_ID is the first column
     jrs.addRowSet(bonus);</span> </pre>
<p> <span>在这一点上， <i>jrs</i>是基于他们的<code>EMP_ID</code>列的两个<code>RowSet</code>对象的内部JOIN。</span> <span>该应用程序现在可以浏览组合的数据，就像浏览一个单一的<code>RowSet</code>对象一样。</span> <span>因为<i>jrs</i>本身是一个<code>RowSet</code>对象，应用程序可以使用<code>RowSet</code>方法导航或修改它。</span> </p>
<pre>  <span>jrs.first();
     int employeeID = jrs.getInt(1);
     String employeeName = jrs.getString(2);</span> </pre>
<p> <span>请注意，由于SQL <code>JOIN</code>当应用程序增加了第二个或后续必须执行<code>RowSet</code>对象而，有可能是在性能初始降解<code>JOIN</code>正在执行的。</span> </p>
<p> <span>以下代码片段添加了一个附加的<code>CachedRowSet</code>对象。</span> <span>在这种情况下，当<code>CachedRowSet</code>对象被添加到<code>JoinRowSet</code>对象时，匹配列（ <code>EMP_ID</code> ）被设置。</span> </p>
<pre>  <span>ResultSet rs3 = stmt.executeQuery("SELECT * FROM 401K_CONTRIB");
     CachedRowSet fourO1k = new CachedRowSetImpl();
     four01k.populate(rs3);
     jrs.addRowSet(four01k, 1);</span> </pre>
<p> <span><code>JoinRowSet</code>对象<i>jrs</i>现在包含来自所有三个表的值。</span> <span>其中用于所述值在<i>four01k</i>每一行中的数据<code>EMP_ID</code>柱为相匹配的值<code>EMP_ID</code>在<i>JRS</i>列已被添加到<i>JRS。</i></span> </p>
<h3> <span>4.0 <code>JoinRowSet</code>方法</span> </h3>
<span><code>JoinRowSet</code>接口提供了几种添加<code>RowSet</code>对象的方法，并提供有关<code>JoinRowSet</code>对象的信息。</span>
<ul>
<li> <span>添加一个或多个<code>RowSet</code>对象的方法</span> <br/> <span>这些方法允许应用程序一次添加一个<code>RowSet</code>对象，或者一次添加多个<code>RowSet</code>对象。</span> <span>在这两种情况下，方法可以为要添加的每个<code>RowSet</code>对象指定匹配列。</span> </li>
<li> <span>获取信息的方法</span> <br/> <span>一种方法检索<code>RowSet</code>对象中的<code>JoinRowSet</code>对象，另一种方法检索<code>RowSet</code>名称。</span> <span>第三种方法检索幕后使用的SQL <code>WHERE</code>子句以形成<code>JOIN</code>或<code>WHERE</code>子句的文本描述。</span> </li>
<li> <span>方法与<code>JOIN</code>类型有关</span> <br/> <span>一种方法设置<code>JOIN</code>类型，五种方法查找<code>JoinRowSet</code>对象是否支持给定类型。</span> </li>
<li> <span>制作<code>JoinRowSet</code>对象的单独副本的方法</span> <br/> <span>此方法创建可以持久保存到数据源的副本。</span> </li>
