<p>Answer:</p>

<p>Answer:</p>
<p>Note that, in Oracle&rsquo;s metadata, the tableName and columnName is default UPPERCASE, while double-quoted such as <code>CREATE TABLE &quot;TableName&quot;(&quot;Id&quot; number)</code> the tableName and columnName is the actual content double-quoted, refer to the following SQL for the reality in metadata:</p>
<div class="highlight"><pre style="color:#f8f8f2;background-color:#272822;-moz-tab-size:4;-o-tab-size:4;tab-size:4"><code class="language-sql" data-lang="sql"><span style="color:#66d9ef">SELECT</span> <span style="color:#66d9ef">OWNER</span>, <span style="color:#66d9ef">TABLE_NAME</span>, <span style="color:#66d9ef">COLUMN_NAME</span>, DATA_TYPE <span style="color:#66d9ef">FROM</span> ALL_TAB_COLUMNS <span style="color:#66d9ef">WHERE</span> <span style="color:#66d9ef">TABLE_NAME</span> <span style="color:#66d9ef">IN</span> (<span style="color:#e6db74">&#39;TableName&#39;</span>)

<p>Answer:</p>
<p>Incompatibility between multiple MySQL drivers. Because the MySQL5 version of the driver class under the class path is loaded first, when trying to call the <code>unwrap</code> method in the MySQL8 driver, the type conversion exception occurs.</p>
<p>The solutions:
Check whether there are both MySQL5 and MySQL8 drivers in the class path, and only keep one driver package of the corresponding version.</p>
<p>The exception stack is as follows:</p>

<p>Answer:</p>
<p><code>${...}</code> or <code>$-&gt;{...}</code> can be used in inline expression identifiers, but the former one clashes with place holders in Spring property files, so <code>$-&gt;{...}</code> is recommended to be used in Spring as inline expression identifiers.</p>

<p>Answer:</p>
<p>You must make sure the field in the database table is consistent with that in the sharding algorithms. For example, the field type in database is int(11) and the sharding type corresponds to genetic type is Integer. If you want to configure Long type, please make sure the field type in the database is bigint.</p>

<p>Answer:</p>
<p>When implementing the <code>doSharding</code> method, it is not recommended to specify the specific type of <code>Comparable</code> in the method declaration, but to convert the type in the implementation of the <code>doSharding</code> method. You can refer to the <code>ModShardingAlgorithm#doSharding</code> method.</p>
<h3 id="sharding-why-is-the-default-distributed-auto-augment-key-strategy-provided-by-shardingsphere-not-continuous-and-most-of-them-end-with-even-numbers">[Sharding] Why is the default distributed auto-augment key strategy provided by ShardingSphere not continuous and most of them end with even numbers?</h3>
<p>Answer:</p>
<p>ShardingSphere uses snowflake algorithms as the default distributed auto-augment key strategy to make sure unrepeated and decentralized auto-augment sequence is generated under the distributed situations. Therefore, auto-augment keys can be incremental but not continuous.
But the last four numbers of snowflake algorithm are incremental value within one millisecond. Thus, if concurrency degree in one millisecond is not high, the last four numbers are likely to be zero, which explains why the rate of even end number is higher.
In 3.1.0 version, the problem of ending with even numbers has been totally solved, please refer to: <a href="https://github.com/apache/shardingsphere/issues/1617">https://github.com/apache/shardingsphere/issues/1617</a></p>

<p>Answer:</p>
<p><a href="https://docs.oracle.com/javase/tutorial/sound/SPI-intro.html">Service Provider Interface (SPI)</a> is a kind of API for the third party to implement or expand. Except implementing interface, you also need to create a corresponding file in <code>META-INF/services</code> to make the JVM load these SPI implementations.
More detail for SPI usage, please search by yourself.

<h3 id="sharding-in-addition-to-internal-distributed-primary-key-does-shardingsphere-support-other-native-auto-increment-keys">[Sharding] In addition to internal distributed primary key, does ShardingSphere support other native auto-increment keys?</h3>
<p>Answer:</p>
<p>Yes. But there is restriction to the use of native auto-increment keys, which means they cannot be used as sharding keys at the same time.
Since ShardingSphere does not have the database table structure and native auto-increment key is not included in original SQL, it cannot parse that field to the sharding field. If the auto-increment key is not sharding key, it can be returned normally and is needless to be cared. But if the auto-increment key is also used as sharding key, ShardingSphere cannot parse its sharding value, which will make SQL routed to multiple tables and influence the rightness of the application.
The premise for returning native auto-increment key is that INSERT SQL is eventually routed to one table. Therefore, auto-increment key will return zero when INSERT SQL returns multiple tables.</p>

<p>Answer:</p>
<p>To ensure the readability of source code,the ShardingSphere Coding Specification requires that the naming of classes,methods and variables be literal and avoid abbreviations,which may result in some source files have long names.
Since the Git version of Windows is compiled using msys,it uses the old version of Windows Api,limiting the file name to no more than 260 characters.
The solutions are as follows:
Open cmd.exe (you need to add git to environment variables) and execute the following command to allow git supporting log paths:</p>
<pre><code>git config --global core.longpaths true
</code></pre><p>If we use windows 10, also need enable win32 log paths in registry editor or group strategy(need reboot):</p>
<blockquote>
<p>Create the registry key <code>HKLM\SYSTEM\CurrentControlSet\Control\FileSystem LongPathsEnabled</code> (Type: REG_DWORD) in registry editor, and be set to 1.
Or click &ldquo;setting&rdquo; button in system menu, print &ldquo;Group Policy&rdquo; to open a new window &ldquo;Edit Group Policy&rdquo;, and then click &lsquo;Computer Configuration&rsquo; &gt; &lsquo;Administrative Templates&rsquo; &gt; &lsquo;System&rsquo; &gt; &lsquo;Filesystem&rsquo;, and then turn on &lsquo;Enable Win32 long paths&rsquo; option.

<p>Answer:</p>
<p>In Apache ShardingSphere, many functionality implementation are uploaded through <a href="https://shardingsphere.apache.org/document/current/en/concepts/pluggable/">SPI</a>, such as Distributed Primary Key. These functions load SPI implementation by configuring the <code>type</code>, so the <code>type</code> must be specified in the configuration file.</p>

<h3 id="other-why-is-the-database-sharding-result-not-correct-when-using-proxool">[Other] Why is the database sharding result not correct when using <code>Proxool</code>?</h3>
<p>Answer:</p>
<p>When using <code>Proxool</code> to configure multiple data sources, each one of them should be configured with alias. It is because <code>Proxool</code> would check whether existing alias is included in the connection pool or not when acquiring connections, so without alias, each connection will be acquired from the same data source.
The followings are core codes from ProxoolDataSource getConnection method in <code>Proxool</code>:</p>
