<% group # Abstract accessors %> <% order # 20 %> <p class="j">The following example demonstrates how to create and use an abstract data accessor class. All abstract methods of the class are generated at run-time depending on each method declaration. Every part of the method declaration is important. Method's return value specifies one of the Execute methods in the following way: <table class='data'> <tr><th>Return Type</th><th>Execute Method</th></tr> <tr><td><i>IDataReader</i> interface</td><td>ExecuteReader</td></tr> <tr><td>Subclass of <i>DataSet</i></td><td>ExecuteDataSet</td></tr> <tr><td>Subclass of <i>DataTable</i></td><td>ExecuteDataTable</td></tr> <tr><td>Class implementing the <i>IList</i> interface</td><td><a href="ExecuteList.htm">ExecuteList</a> or <a href="ExecuteList.htm">ExecuteScalarList</a></td></tr> <tr><td>Class implementing the <i>IDictionary</i> interface</td><td><a href="ExecuteDictionary.htm">ExecuteDictionary</a> or <a href="ExecuteDictionary.htm">ExecuteScalarDictionary</a></td></tr> <tr><td><i>void</i></td><td>ExecuteNonQuery</td></tr> <tr><td><i>string</i>, <i>byte[]</i> or value type</td><td><a href="ExecuteScalar.htm">ExecuteScalar</a></td></tr> <tr><td>In any other case</td><td><a href="ExecuteObject.htm">ExecuteObject</a></td></tr> </table> Method name explicitly defines action name which is converted to stored procedure name.<br/> Type, sequential order, and name of the method parameters is mapped to the command parameters. Exceptions from this rule are: <br> <div style="margin:-10px 0px -10px -10px"><ul compact="compact"> <li>a parameter of <a href="../Data/index.htm"><i>DbManager</i></a> type. In this case generator uses provided <a href="../Data/index.htm"><i>DbManager</i></a> to call the command.</li> <li>parameters decorated with attribute <i>FormatAttribute</i>.</li> </ul></div> </p> AbstractAccessor.cs <% ..\..\..\HowTo\DataAccess\AbstractAccessor.cs %> <a name='Person'></a> Person.cs <% ..\..\..\HowTo\DataAccess\Person.cs %> Gender.cs <% ..\..\..\HowTo\DataAccess\Gender.cs %> App.config <% Doc\Data\App.config %> <a href="../Data/CreateSql.htm">Create.sql script</a>
