-<h1>Exploring the SQLMap PHP DataMapper API through the <tt>TSqlMapper</tt></h1>
-<p>The <tt>TSqlMapper</tt> instance acts as a facade to provide access the rest of
-the DataMapper framework. The DataMapper API methods are shown below.</p>
-
-<com:TTextHighlighter Language="php" CssClass="source">
-/* Query API */
-public function queryForObject($statementName, $parameter=null, $result=null);
-public function queryForList($statementName, $parameter=null, $result=null,
- $skip=-1, $max=-1);
-public function queryForPagedList($statementName, $parameter=null, $pageSize=10);
-public function queryForMap($statementName, $parameter=null,
- $keyProperty=null, $valueProperty=null);
-public function insert($statementName, $parameter=null)
-public function update($statementName, $parameter=null)
-public function delete($statementName, $parameter=null)
-
-/* Connection API */
-public function openConnection()
-public function closeConnection()
-
-/* Transaction API */
-public function beginTransaction()
-public function commitTransaction()
-public function rollBackTransaction()
-</com:TTextHighlighter>
-
-<p>Note that each of the API methods accept the name of the Mapped Statement as
-the first parameter. The <tt>statementName</tt> parameter corresponds to the
-<tt>id</tt> of the Mapped Statement in the Data Map definition.
-In each case, a <tt>parameterObject</tt> also may be
-passed. The following sections describe how the API methods work.</p>
-
-<h2>Insert, Update, Delete</h2>
-<com:TTextHighlighter Language="php" CssClass="source">
-public function insert($statementName, $parameter=null)
-public function update($statementName, $parameter=null)
-public function delete($statementName, $parameter=null)
-</com:TTextHighlighter>
-
-<p>If a Mapped Statement uses one of the <tt><insert></tt>, <tt><update></tt>, or
-<tt><delete></tt> statement-types, then it should use the corresponding API
-method. The <tt><insert></tt> element supports a nested <tt><selectKey></tt> element
-for generating primary keys. If the
-<tt><selectKey></tt> stanza is used, then <tt>insert</tt> returns the generated key;
-otherwise a null object is returned. Both the <tt>update</tt> and <tt>delete</tt>
-methods return the number of rows affected by the statement.
-</p>
-
-<h2>QueryForObject</h2>
-<com:TTextHighlighter Language="php" CssClass="source">
-public function queryForObject($statementName, $parameter=null, $result=null);
-</com:TTextHighlighter>
-
-<p>If a Mapped Statement is expected to select a single row, then call it using
-<tt>queryForObject</tt>. Since the Mapped Statement definition specifies the
-result class expected, the framework can both create and populate the result
-class for you. Alternatively, if you need to manage the result object
-yourself, say because it is being populated by more than one statement, you
-can use the alternate form and pass your <tt>$resultObject</tt> as the third
-parameter.</p>
-
-<h2>QueryForList</h2>
-
-<com:TTextHighlighter Language="php" CssClass="source">
-public function queryForList($statementName, $parameter=null, $result=null,
- $skip=-1, $max=-1);
-</com:TTextHighlighter>
-
-<p>If a Mapped Statement is expected to select multiple rows, then call it using
-<tt>queryForList</tt>. Each entry in the list will be an result object populated
-from the corresponding row of the query result. If you need to manage the
-<tt>$resultObject</tt> yourself, then it can be passed as the third parameter. If
-you need to obtain a partial result, the fourth parameter <tt>$skip</tt> and
-fifth parameter <tt>$max</tt> allow you to skip a number of records (the starting
-point) and the maximum number to return.</p>
-
-<h2>QueryForPagedList</h2>
-<com:TTextHighlighter Language="php" CssClass="source">
- public function queryForPagedList($statementName, $parameter=null, $pageSize=10);
-</com:TTextHighlighter>
-
-<p>We live in an age of information overflow. A database query often returns more
-hits than users want to see at once, and our requirements may say that we need
-to offer a long list of results a "page" at a time. If the query returns
-1000 hits, we might need to present the hits to the user in sets of fifty, and
-let them move back and forth between the sets. Since this is such a common
-requirement, the framework provides a convenience method.</p>
-
-<p>The <tt>TSqlMapPagedList</tt> interface includes methods for navigating through
-pages (<tt>nextPage()</tt>, <tt>previousPage()</tt>, <tt>gotoPage($pageIndex)</tt>) and
-also checking the status of the page (<tt>getIsFirstPage()</tt>,
-<tt>getIsMiddlePage()</tt>, <tt>getIsLastPage()</tt>, <tt>getIsNextPageAvailable()</tt>,
-<tt>getIsPreviousPageAvailable()</tt>, <tt>getCurrentPageIndex()</tt>,
-<tt>getPageSize()</tt>). The total number of records available is not accessible
-from the <tt>TSqlMapPagedList</tt> interface, unless a virtual count is defined
-using <tt>setVirtualCount($value)</tt>, this should be easily accomplished by
-simply executing a second statement that counts the expected results.</p>
-
-<div class="tip"><b class="tip">Tip:</b>
-The <tt>queryForPagedList</tt> method is convenient, but note that a larger set
-(up to 3 times the page size) will first be returned by the database provider
-and the smaller set extracted by the framework. The higher the page size, the
-larger set that will be returned and thrown away. For very large sets, you may
-want to use a stored procedure or your own query that uses <tt>$skip</tt> and
-<tt>$max</tt> as parameters in <tt>queryForList</tt>.
-</div>
-
-<h2>QueryForMap</h2>
-<com:TTextHighlighter Language="php" CssClass="source">
-public function queryForMap($statementName, $parameter=null,
- $keyProperty=null, $valueProperty=null);
-</com:TTextHighlighter>
-
-<p>The <tt>queryForList</tt> methods return the result objects within a <tt>TList</tt> or
-array instance. Alternatively, the <tt>queryForMap</tt> returns a TMap or
-associative array instance. The value of each entry is one of the result
-objects. The key to each entry is indicated by the <tt>$keyProperty</tt>
-parameter. This is the name of the one of the properties of the result object,
-the value of which is used as the key for each entry. For example, If you
-needed a set of <tt>Employee</tt> objects, you might want them returned as a
-<tt>TMap</tt> keyed by each object's <tt>EmployeeNumber</tt> property.</p>
-
-<p>If you don't need the entire result object in your result, you can add the
-<tt>$valueProperty</tt> parameter to indicate which result object property should
-be the value of an entry. For example, you might just want the
-<tt>EmployeeName</tt> keyed by <tt>EmployeeNumber</tt>.</p>
-
-<h2>Transaction</h2>
-<p>The DataMapper API includes methods to demarcate transactional boundaries. A
-transaction can be started, committed and/or rolled back. You can call the
-transaction methods from the <tt>TSqlMapper</tt> instance.</p>
-
-<com:TTextHighlighter Language="php" CssClass="source">
-// Begin a transactional session using Adodb transaction API
-public function beginTransaction()
-
-// Commit a transaction, uses Adodb transaction API
-public function commitTransaction()
-
-// RollBack a transaction, uses Adodb transaction API
-public void RollBackTransaction()
-</com:TTextHighlighter>
-
-<p>Using transactions example.</p>
