<h2>7.5. OLE DB Provider for Virtuoso</h2>
<p>OLE DB is an open data access technology developed and promoted by Microsoft.
It allows for uniform data access across diverse data sources including but not
limited to conventional RDBMSes. Based on the COM architecture it provides very
flexible and exhaustive set of interfaces any database application developer might
ever need. At the same time, OLE DB is somewhat overcomplicated and therefore
is rarely used directly. In the majority of cases people use ADO(+) instead, ADO is
another, somewhat simpler, of Microsoft's data access technologies. However,
ADO itself is based upon OLE DB, thus those who use ADO make indirect use of
OLE DB as well.</p>
<p>With the advent of ADO.NET, OLE DB is no longer as an much essential
part of the overall Microsoft data access architecture as it used to be.
However it still remains important and useful working together with the
Microsoft OLE DB .NET Data Provider.</p>
<p>The OLE DB Provider for Virtuoso (VIRTOLEDB) gives OLE DB and ADO
applications access to the Virtuoso databases. In principle, the same thing is
possible through the conjunction of the Virtuoso ODBC driver and Microsoft
OLE DB Provider for ODBC. However, VIRTOLEDB provides native OLE DB access
which is more complete and more efficient. Therefore it is preferable for
this purpose.</p>
<a name="oledbusing" />
<h3>7.5.1. Using the OLE DB Provider for Virtuoso</h3>
<p>Being a COM in-process server VIRTOLEDB has to be installed on the client computer.
When VIRTOLEDB is properly installed it can be used by a host of existing applications thanks
to the support of standard OLE DB interfaces.</p>
<a name="oledbrequirements" />
<h4>7.5.1.1. System Requirements</h4>
<p>VIRTOLEDB requires the following software:
<ul>
<li>
Windows 98, ME, NT4.0, 2000, or XP.
</li>
<li>
Virtuoso Server running on the same or remote computer.
</li>
<li>
Redistributable files provided with Microsoft Data Access Components
(MDAC) 2.5 or higher. Note that this version of MDAC comes along with
Windows 2000. It is also available (as well as other versions of MDAC)
at the Microsoft Web site: <a href="http://www.microsoft.com/data/">http://www.microsoft.com/data/</a>
</li>
</ul>
</p>
<br />
<a name="oledbinstalling" />
<h4>7.5.1.2. Installing the Provider</h4>
<p>VIRTOLEDB is installed as a part of Virtuoso installation on a Windows
platform. The following files pertain to the OLE DB Provider for Virtuoso.</p>
<table class="data">
<caption>Table: 7.5.1.2.1. OLE DB Provider for Virtuoso Files</caption>
<tr>
<th class="data">File</th>
<th class="data">Description</th>
</tr>
<tr>
<td class="data">virtoledb.dll</td>
<td class="data">DLL that implements the VIRTOLEDB provider.</td>
</tr>
<tr>
<td class="data">virtoledb.h</td>
<td class="data">Header file for development of VIRTOLEDB consumers.</td>
</tr>
</table>
<br />
<p>The installation procedure, in addition to placing VIRTOLEDB files
on a client computer, also registers VIRTOLEDB in the system to make it
known as a COM server. This also makes it available through the OLE DB
root enumerator object and the Data Links component.</p>
<br />
<a name="oledbinvoking" />
<h4>7.5.1.3. Invoking the Provider</h4>
<p>Applications that utilize OLE DB Data Links component can use VIRTOLEDB
without any specific measures. Applications that need to directly invoke
VIRTOLEDB should follow examples provided in this section.</p>
<a name="datalinks" />
<h5>7.5.1.3.1. Using Data Link User Interface</h5>
<p>Data Links is a user interface component for connecting to OLE DB
data sources and constructing ADO-style connection strings. It belongs
to OLE DB core components and is a part of MDAC. It is used my many
applications including development environments like MS Visual Studio.</p>
<p>VIRTOLEDB uses the extension mechanism of the Data Link API and
provides a customized version of the Data Link connection page.</p>

<h4>7.5.3.2. Data Type Conversions</h4>
<p>Applications can bind column and parameter values using data types
different from those described in . In such cases
VIRTOLEDB uses OLE DB Data Conversion Library. See MDAC documentation for the
list of supported data type conversions.</p>
<br />
<a name="longdata" />
<h4>7.5.3.3. Long Data Types</h4>
<p>Long data types include LONG VARCHAR, LONG NVARCHAR, and LONG VARBINARY.
A long value can only be bound to a buffer that have one of these OLE DB types:</p>
<ul>
<li>DBTYPE_IUNKNOWN</li>
<li>DBTYPE_STR</li>
<li>DBTYPE_STR | DBTYPE_BYREF</li>
<li>DBTYPE_WSTR</li>
<li>DBTYPE_WSTR | DBTYPE_BYREF</li>
<li>DBTYPE_BYTES</li>
<li>DBTYPE_BYTES | DBTYPE_BYREF</li>
</ul>
<p>Other type conversions are not supported.</p>
<p>If a long data is bound to a DBTYPE_IUNKNOWN type, this implies
the use of the ISequentialStream interface. VIRTOLEDB supports the
ISequentialStream::Read method both when getting and setting data.
The ISequentialStream::Write method is never supported.</p>
