<h1>JDBC Driver</h1>
<div id="preamble">
<div class="sectionbody">
<div class="paragraph">
<p>Apache Ignite is shipped with JDBC driver that allows processing of distributed data using standard SQL statements like <code>SELECT</code>, <code>INSERT</code>, <code>UPDATE</code>, or <code>DELETE</code> directly from the JDBC side.</p>
</div>
<div class="paragraph">
<p>WARNING:</p>
</div>
<div class="listingblock">
<div class="content">
<pre>This Alpha release implementation of JDBC driver does not support the following functionality:
* SSL/TLS connection;
* Multiple Endpoints;
* Partition Awareness;
* `CREATE TABLE`, `ALTER TABLE`, `WITH`, and `MERGE` commands.</pre>
</div>
</div>
</div>
</div>
<div class="sect1">
<h2 id="setting-up">Setting Up</h2>
<div class="sectionbody">
<div class="paragraph">
<p>The name of the driver’s class is <code>org.apache.ignite.jdbc.IgniteJdbcDriver</code>. For instance, this is how you can open a JDBC connection to the cluster node listening on IP address <code>192.168.0.50</code>:</p>

<p>The driver connects to one of the cluster nodes and forwards all the queries to it for final execution. The node handles the query distribution and the result’s aggregations. Then the result is sent back to the client application.</p>

<p>The JDBC connection string may be formatted with one of two patterns: <code>URL query</code> or <code>semicolon</code>:</p>
