<p>
The <a href="../api_reference/C/dbget.html" class="olink">DB->get()</a> method retrieves records from the database. In
general, <a href="../api_reference/C/dbget.html" class="olink">DB->get()</a> takes a key and returns the associated data
from the database.
</p>
<p>
There are a few flags that you can set to customize
retrieval:
</p>
<div class="variablelist">
<dl>
<dt>
<span class="term">
<a href="../api_reference/C/dbget.html#get_DB_GET_BOTH" class="olink">DB_GET_BOTH</a>
</span>
</dt>
<dd>
Search for a matching key and data item, that
is, only return success if both the key and the data
items match those stored in the database.
</dd>
<dt>
<span class="term">
<a href="../api_reference/C/dbcget.html#dbcget_DB_RMW" class="olink">DB_RMW</a>
</span>
</dt>
<dd>
Read-modify-write: acquire write locks instead
of read locks during retrieval. This can enhance
performance in threaded applications by reducing the
chance of deadlock.
</dd>
<dt>
<span class="term">
<a href="../api_reference/C/dbget.html#dbget_DB_SET_RECNO" class="olink">DB_SET_RECNO</a>
</span>
</dt>
<dd>
If the underlying database is a Btree, and was
configured so that it is possible to search it by
logical record number, retrieve a specific
record.
</dd>
</dl>
</div>
<p>
If the database has been configured to support duplicate
records, <a href="../api_reference/C/dbget.html" class="olink">DB->get()</a> will always return the first data item in the
duplicate set.
</p>
