<a name="id-1.9.7.12"></a>Methods - data representation</h2></div></div></div>
<p>
This group of virtual methods is related to converting some data between the three representations which are the
SQL representation (to be directly included in a SQL statement), the human readable representation, and the
<a href="/usr/share/gtk-doc/html/gobject/gobject-Generic-values.html#GValue">GValue</a> representation. For each type of data (identified as a
<a href="/usr/share/gtk-doc/html/gobject/gobject-Type-Information.html#GType">GType</a> type) which the provider can handle, a <a class="link" href="libgda-5.0-Default-Data-handlers.html#GdaDataHandler">GdaDataHandler</a>
object is responsible of the conversions.
</p>
<div class="sect2">
<div class="titlepage"><div><div><h3 class="title">
<a name="id-1.9.7.12.3"></a>get_data_handler()</h3></div></div></div>
<p>
This method returns a <a class="link" href="libgda-5.0-Default-Data-handlers.html#GdaDataHandler">GdaDataHandler</a> for the requested data type. It should
only instantiate each <a class="link" href="libgda-5.0-Default-Data-handlers.html#GdaDataHandler">GdaDataHandler</a> once and reuse it if the same request happens
(the returned object will not be modified).
</p>
<p>
This method is called by both
<a class="link" href="GdaServerProvider.html#gda-server-provider-get-data-handler-g-type" title="gda_server_provider_get_data_handler_g_type ()">gda_server_provider_get_data_handler_g_type()</a> and
<a class="link" href="GdaServerProvider.html#gda-server-provider-get-data-handler-dbms" title="gda_server_provider_get_data_handler_dbms ()">gda_server_provider_get_data_handler_dbms()</a> methods.

<div class="titlepage"><div><div><h3 class="title">
<a name="id-1.9.7.12.4"></a>get_def_dbms_type()</h3></div></div></div>
<p>
This method returns the name of the most common (database specific) data type which has the requested type.
</p>
</div>
<div class="sect2">
<div class="titlepage"><div><div><h3 class="title">
<a name="id-1.9.7.12.5"></a>escape_string()</h3></div></div></div>
<p>
This method adds escape characters to a string, to be able to safely add it into an SQL statement.
</p>
</div>
<div class="sect2">
<div class="titlepage"><div><div><h3 class="title">
<a name="id-1.9.7.12.6"></a>unescape_string()</h3></div></div></div>
<p>
This method does the reverse of the escape_string() method.
