<p>
On the contrary to data manipulation (DML) queries, data definition queries are not very well standardized (the SQL varies a
lot from one DBMS to the other), and <span class="application">Libgda</span> proposes to bypass the SQL usage and uses a different approach based on the
information required to perform a task (or operation, thus the <a class="link" href="GdaServerOperation.html" title="GdaServerOperation">GdaServerOperation</a>
object).
</p>
<p>
Here is an overview the steps involved:
</p>
<div class="itemizedlist"><ul class="itemizedlist" type="disc">
<li class="listitem"><p>Make sure the database provider (associated to the connection) supports the requested operation using the
<a class="link" href="GdaServerProvider.html#gda-server-provider-supports-operation" title="gda_server_provider_supports_operation ()">gda_server_provider_supports_operation()</a> method</p></li>
<li class="listitem">
<p>Ask the provider to create a <a class="link" href="GdaServerOperation.html" title="GdaServerOperation">GdaServerOperation</a> object
using the <a class="link" href="GdaServerProvider.html#gda-server-provider-create-operation" title="gda_server_provider_create_operation ()">gda_server_provider_create_operation()</a> method.
The resulting new object will hold all the information required (and some optional) to perform the requested
operation. For example to create a table, the required information will be the table name and the description of its
columns, and the optional information might be the schema in which to create the table for a PostgreSQL provider.</p>
<p>
Additionally some options can be passed when using that function in the form of named parameters, see <a class="link" href="ch20.html#gda-server-op-information-std" title="Standard named information">this section</a> for more information.
</p>
</li>
<li class="listitem"><p>Fill in the values (required or optional) of the <a class="link" href="GdaServerOperation.html" title="GdaServerOperation">GdaServerOperation</a>
object (see the GdaServerOperation object's <a class="link" href="GdaServerOperation.html" title="GdaServerOperation">documentation</a> for more information).
</p></li>
<li class="listitem"><p>Use that object to request the actual operation to be done using the
<a class="link" href="GdaServerProvider.html#gda-server-provider-perform-operation" title="gda_server_provider_perform_operation ()">gda_server_provider_perform_operation()</a> method.
Afterwards that object can be discarded using <a href="http://library.gnome.org/devel/gobject/unstable/gobject-The-Base-Object-Type.html#g-object-unref">g_object_unref()</a></p></li>
</ul></div>
<p>
The information stored within a <a class="link" href="GdaServerOperation.html" title="GdaServerOperation">GdaServerOperation</a> object can also be stored within
an XML structure and re-loaded later, which for example allows to create "scripts" of operations to do.
</p>
<div class="sect3">
<div class="titlepage"><div><div><h4 class="title">
<a name="id846246"></a>Organization of the required information</h4></div></div></div>
<p>
The required information to perform an operation is stored entirely in a
<a class="link" href="GdaServerOperation.html" title="GdaServerOperation">GdaServerOperation</a> object using named paths which are strings like
"/TABLE_DEF_P/TABLE_NAME" or "/TABLE_CONSTRAINTS_S/0/CONSTRAINT_STRING" (for details about the path format, refer to the
<a class="link" href="GdaServerOperation.html#gda-server-operation-set-value-at" title="gda_server_operation_set_value_at ()">gda_server_operation_set_value_at()</a> method).
Each path is similar to a Unix file path
(names separated by a '/'). Each part of the path corresponds to a node (represented as a
<a class="link" href="libgda-4.0-GdaServerOperation-individual-nodes.html#GdaServerOperationNode" title="GdaServerOperationNode">GdaServerOperationNode</a> structure) which has a type listed as
a <a class="link" href="libgda-4.0-GdaServerOperation-individual-nodes.html#GdaServerOperationNodeType" title="enum GdaServerOperationNodeType">GdaServerOperationNodeType</a>; basically the types of node are:
</p>
<div class="itemizedlist"><ul class="itemizedlist" type="disc">
<li class="listitem"><p>a node containing a <a class="link" href="GdaHolder.html" title="GdaHolder">GdaHolder</a> object which just contains one value</p></li>
<li class="listitem"><p>a node containing a <a class="link" href="GdaSet.html" title="GdaSet">GdaSet</a> object which is just a list
of named parameters (for example all the attributes of the table to create such as the table's name and
storage type for a MySQL provider)</p></li>
<li class="listitem"><p>a node containing a <a class="link" href="GdaDataModel.html" title="GdaDataModel">GdaDataModel</a> object when the needed information
is tabular (rows and columns), for example the definition of all the columns to create in a table, each column having
a name, type, CHECK constraint, etc</p></li>
<li class="listitem"><p>a node defining a sequence of items: the sequence node can have zero or more items composed of nodes.
For example when
defining the foreign keys for a new table, a sequence node can be created which can contain zero or more foreign key
definition items (each composed of the referenced table, the referenced fields, the referential integrity rules, etc)
</p></li>
<li class="listitem"><p>a node representing an 'item' in a sequence node (that is a list of nodes).</p></li>
<li class="listitem"><p>a node representing a data model's column.</p></li>
</ul></div>
<p>
</p>
<p>
Note: the list and complete structure of the information required to perform an operation is imposed by each provider and cannot
be modified. The information stored in each node can be modified (depending on the node's type):
</p>
</div>
<div class="sect3">
<div class="titlepage"><div><div><h4 class="title">
<a name="gda-server-op-information-specif"></a>Provider specific information</h4></div></div></div>
<p>
To list the possible/required parameters for each provider, use the
<a class="link" href="libgda-list-server-op.html" title="gda-list-server-op-4.0">gda-list-server-op</a> tool.
</p>
</div>
<div class="sect3">
<div class="titlepage"><div><div><h4 class="title">
<a name="gda-server-op-information-std"></a>Standard named information</h4></div></div></div>
<p>
For most of the possible operations, the required information from one provider to the other does not vary, only the
optional features correspond to optional information, so <span class="application">Libgda</span> imposes the names of the required information for
some of the most common operations, which is shown next. Some optional information which is shared by several providers
is also named but not enforced.
