Alternatively, you can use scripts to load tsfiles into IoTDB, for more information.</p><h2 id="load-with-sql" tabindex="-1"><a class="header-anchor" href="#load-with-sql" aria-hidden="true">#</a> Load with SQL</h2><p>The user sends specified commands to the Apache IoTDB system through the Cli tool or JDBC to use the tool.</p><h3 id="load-tsfiles" tabindex="-1"><a class="header-anchor" href="#load-tsfiles" aria-hidden="true">#</a> load tsfiles</h3><p>The command to load tsfiles is <code>load &lt;path/dir&gt; [sglevel=int][verify=true/false][onSuccess=delete/none]</code>.</p><p>This command has two usages:</p><ol><li>Load a single tsfile by specifying a file path (absolute path).</li></ol><p>The first parameter indicates the path of the tsfile to be loaded. This command has three options: sglevel, verify, onSuccess.</p><p>SGLEVEL option. If the database correspond to the tsfile does not exist, the user can set the level of database through the fourth parameter. By default, it uses the database level which is set in <code>iotdb-datanode.properties</code>.</p><p>VERIFY option. If this parameter is true, All timeseries in this loading tsfile will be compared with the timeseries in IoTDB. If existing a measurement which has different datatype with the measurement in IoTDB, the loading process will be stopped and exit. If consistence can be promised, setting false for this parameter will be a better choice.</p><p>ONSUCCESS option. The default value is DELETE, which means the processing method of successfully loaded tsfiles, and DELETE means after the tsfile is successfully loaded, it will be deleted. NONE means after the tsfile is successfully loaded, it will be remained in the origin dir.</p><p>If the <code>.resource</code> file corresponding to the file exists, it will be loaded into the data directory and engine of the Apache IoTDB. Otherwise, the corresponding <code>.resource</code> file will be regenerated from the tsfile file.</p><p>Examples:</p><ul><li><code>load &#39;/Users/Desktop/data/1575028885956-101-0.tsfile&#39;</code></li><li><code>load &#39;/Users/Desktop/data/1575028885956-101-0.tsfile&#39; verify=true</code></li><li><code>load &#39;/Users/Desktop/data/1575028885956-101-0.tsfile&#39; verify=false</code></li><li><code>load &#39;/Users/Desktop/data/1575028885956-101-0.tsfile&#39; sglevel=1</code></li><li><code>load &#39;/Users/Desktop/data/1575028885956-101-0.tsfile&#39; onSuccess=delete</code></li><li><code>load &#39;/Users/Desktop/data/1575028885956-101-0.tsfile&#39; verify=true sglevel=1</code></li><li><code>load &#39;/Users/Desktop/data/1575028885956-101-0.tsfile&#39; verify=false sglevel=1</code></li><li><code>load &#39;/Users/Desktop/data/1575028885956-101-0.tsfile&#39; verify=true onSuccess=none</code></li><li><code>load &#39;/Users/Desktop/data/1575028885956-101-0.tsfile&#39; verify=false sglevel=1 onSuccess=delete</code></li></ul><ol start="2"><li>Load a batch of files by specifying a folder path (absolute path).</li></ol><p>The first parameter indicates the path of the tsfile to be loaded.
