 <h3 id="jdbc-oracle-表名字段名配置大小写在加载-metadata-元数据时结果不正确">[JDBC] Oracle 表名、字段名配置大小写在加载 <code>metadata</code> 元数据时结果不正确？</h3>
 <p>回答：
 需要注意，Oracle 表名和字段名，默认元数据都是大写，除非建表语句中带双引号，如 <code>CREATE TABLE &quot;TableName&quot;(&quot;Id&quot; number)</code> 元数据为双引号中内容，可参考以下SQL查看元数据的具体情况：</p>

 <p>回答：</p>
 <ol>
 <li>ShardingSphere-Proxy 可以看做是一个 database server，所以首选支持 SQL 命令连接和操作。</li>
 <li>如果使用其他第三方数据库工具，可能由于不同工具的特定实现导致出现异常。</li>
 <li>目前已测试的第三方数据库工具如下：
 <ul>
 <li>DataGrip：2020.1、2021.1（使用 IDEA/DataGrip 时打开 <code>introspect using JDBC metadata</code> 选项）。</li>
 <li>MySQLWorkBench：8.0.25。</li>

 <p>回答：</p>

 <li>第三方数据库工具在连接 ShardingSphere-Proxy 时会发送一些 SQL 查询元数据，当 ShardingSphere-Proxy 没有创建 <code>database</code> 或者没有注册 <code>storage unit</code> 时，ShardingSphere-Proxy 无法执行 SQL。</li>
 <li>推荐先创建 <code>database</code> 并注册 <code>storage unit</code> 之后再使用第三方数据库工具连接。</li>
 <li>有关 <code>storage unit</code> 的详情请参考。<a href="https://shardingsphere.apache.org/document/current/cn/user-manual/shardingsphere-proxy/distsql/syntax/rdl/storage-unit-definition/">相关介绍</a></li>

 <h3 id="分片--shardingsphere-提供的默认分布式自增主键策略为什么是不连续的且尾数大多为偶数">[分片]  ShardingSphere 提供的默认分布式自增主键策略为什么是不连续的，且尾数大多为偶数？</h3>
 <p>回答：</p>
 <p>ShardingSphere 采用 snowflake 算法作为默认的分布式自增主键策略，用于保证分布式的情况下可以无中心化的生成不重复的自增序列。因此自增主键可以保证递增，但无法保证连续。
 而 snowflake 算法的最后 4 位是在同一毫秒内的访问递增值。因此，如果毫秒内并发度不高，最后 4 位为零的几率则很大。因此并发度不高的应用生成偶数主键的几率会更高。
 在 3.1.0 版本中，尾数大多为偶数的问题已彻底解决，参见：https://github.com/apache/shardingsphere/issues/1617</p>

 <p>回答：</p>
 <p><a href="https://docs.oracle.com/javase/tutorial/sound/SPI-intro.html">Service Provider Interface (SPI)</a> 是一种为了被第三方实现或扩展的 API，除了实现接口外，还需要在 META-INF/services 中创建对应文件来指定 SPI 的实现类，JVM 才会加载这些服务。
 具体的 SPI 使用方式，请大家自行搜索。

 <h3 id="分片-shardingsphere-除了支持自带的分布式自增主键之外还能否支持原生的自增主键">[分片] ShardingSphere 除了支持自带的分布式自增主键之外，还能否支持原生的自增主键？</h3>
 <p>回答：</p>
 <p>是的，可以支持。但原生自增主键有使用限制，即不能将原生自增主键同时作为分片键使用。
 由于 ShardingSphere 并不知晓数据库的表结构，而原生自增主键是不包含在原始 SQL 中内的，因此 ShardingSphere 无法将该字段解析为分片字段。如自增主键非分片键，则无需关注，可正常返回；若自增主键同时作为分片键使用，ShardingSphere 无法解析其分片值，导致 SQL 路由至多张表，从而影响应用的正确性。
 而原生自增主键返回的前提条件是 INSERT SQL 必须最终路由至一张表，因此，面对返回多表的 INSERT SQL，自增主键则会返回零。</p>

 <p>回答：</p>
 <p>为保证源码的可读性，ShardingSphere 编码规范要求类、方法和变量的命名要做到顾名思义，避免使用缩写，因此可能导致部分源码文件命名较长。由于 Windows 版本的 Git 是使用 msys 编译的，它使用了旧版本的 Windows Api，限制文件名不能超过 260 个字符。
 解决方案如下：
 打开 cmd.exe（你需要将 git 添加到环境变量中）并执行下面的命令，可以让 git 支持长文件名：</p>
 <pre><code>git config --global core.longpaths true
 </code></pre><p>如果是 Windows 10，还需要通过注册表或组策略，解除操作系统的文件名长度限制（需要重启）：</p>
 <blockquote>
 <p>在注册表编辑器中创建 <code>HKLM\SYSTEM\CurrentControlSet\Control\FileSystem LongPathsEnabled</code>， 类型为 <code>REG_DWORD</code>，并设置为1。
 或者从系统菜单点击设置图标，输入“编辑组策略”， 然后在打开的窗口依次进入“计算机管理” &gt; “管理模板” &gt; “系统” &gt; “文件系统”，在右侧双击“启用 win32 长路径”。

 <p>回答：</p>
 <p>ShardingSphere 中很多功能实现类的加载方式是通过 <a href="https://shardingsphere.apache.org/document/current/cn/concepts/pluggable/">SPI</a> 注入的方式完成的，如分布式主键，注册中心等；这些功能通过配置中 type 类型来寻找对应的 SPI 实现，因此必须在配置文件中指定类型。</p>

 <h3 id="其他-使用-proxool-时分库结果不正确">[其他] 使用 <code>Proxool</code> 时分库结果不正确？</h3>
 <p>回答：</p>
 <p>使用 Proxool 配置多个数据源时，应该为每个数据源设置 alias，因为 Proxool 在获取连接时会判断连接池中是否包含已存在的 alias，不配置 alias 会造成每次都只从一个数据源中获取连接。
 以下是 Proxool 源码中 ProxoolDataSource 类 getConnection 方法的关键代码：</p>
