| 4 <p class="j">The following example demonstrates how to create and use an abstract data accessor class. | |
| 5 All abstract methods of the class are generated at run-time depending on each method declaration. | |
| 6 Every part of the method declaration is important. | |
| 7 Method's return value specifies one of the Execute methods in the following way: | |
| 8 <table class='data'> | |
| 9 <tr><th>Return Type</th><th>Execute Method</th></tr> | |
| 10 <tr><td><i>IDataReader</i> interface</td><td>ExecuteReader</td></tr> | |
| 11 <tr><td>Subclass of <i>DataSet</i></td><td>ExecuteDataSet</td></tr> | |
| 12 <tr><td>Subclass of <i>DataTable</i></td><td>ExecuteDataTable</td></tr> | |
| 13 <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> | |
| 14 <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> | |
| 15 <tr><td><i>void</i></td><td>ExecuteNonQuery</td></tr> | |
| 16 <tr><td><i>string</i>, <i>byte[]</i> or value type</td><td><a href="ExecuteScalar.htm">ExecuteScalar</a></td></tr> | |
| 17 <tr><td>In any other case</td><td><a href="ExecuteObject.htm">ExecuteObject</a></td></tr> | |
| 18 </table> | |
| 19 Method name explicitly defines action name which is converted to stored procedure name.<br/> | |
| 20 Type, sequential order, and name of the method parameters is mapped to the command parameters. | |
| 21 Exceptions from this rule are: | |
| 22 <br> | |
| 23 <div style="margin:-10px 0px -10px -10px"><ul compact="compact"> | |
| 24 <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> | |
| 25 <li>parameters decorated with attribute <i>FormatAttribute</i>.</li> | |
| 26 </ul></div> | |
