abstraction allows you to use transactions with -databases that support transaction-safe table types. In MySQL, you’ll -need to be running InnoDB or BDB table types rather than the more common -MyISAM. Most other database platforms support transactions natively.</p> -<p>If you are not familiar with transactions we recommend you find a good -online resource to learn about them for your particular database. The -information below assumes you have a basic understanding of -transactions.</p> -<div class="section" id="codeigniter-s-approach-to-transactions"> -<h2>CodeIgniter’s Approach to Transactions<a class="headerlink" href="#codeigniter-s-approach-to-transactions" title="Permalink to this headline">¶</a></h2> -<p>CodeIgniter utilizes an approach to transactions that is very similar to -the process used by the popular database class ADODB. We’ve chosen that -approach because it greatly simplifies the process of running -transactions. In most cases all that is required are two lines of code.</p> -<p>Traditionally, transactions have required a fair amount of work to -implement since they demand that you keep track of your queries and -determine whether to commit or rollback based on the success or failure -of your queries. This is particularly cumbersome with nested queries. In -contrast, we’ve implemented a smart transaction system that does all -this for you automatically (you can also manage your transactions -manually if you choose to, but there’s really no benefit).</p> -</div> -<div class="section" id="running-transactions"> -<h2>Running Transactions<a class="headerlink" href="#running-transactions" title="Permalink to this headline">¶</a></h2> -<p>To run your queries using transactions you will use the -$this->db->trans_start() and $this->db->trans_complete() functions as -follows:</p> -<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="nv">$this</span><span class="o">-></span><span class="na">db</span><span class="o">-></span><span class="na">trans_start</span><span class="p">();</span> -<span class="nv">$this</span><span class="o">-></span><span class="na">db</span><span class="o">-></span><span class="na">query</span><span class="p">(</span><span class="s1">'AN SQL QUERY...'</span><span class="p">);</span> -<span class="nv">$this</span><span class="o">-></span><span class="na">db</span><span class="o">-></span><span class="na">query</span><span class="p">(</span><span class="s1">'ANOTHER QUERY...'</span><span class="p">);</span> -<span class="nv">$this</span><span class="o">-></span><span class="na">db</span><span class="o">-></span><span class="na">query</span><span class="p">(</span><span class="s1">'AND YET ANOTHER QUERY...'</span><span class="p">);</span> -<span class="nv">$this</span><span class="o">-></span><span class="na">db</span><span class="o">-></span><span class="na">trans_complete</span><span class="p">();</span> -</pre></div> -</div> -<p>You can run as many queries as you want between the start/complete -functions and they will all be committed or rolled back based on success -or failure of any given query.</p> -</div> -<div class="section" id="strict-mode"> -<h2>Strict Mode<a class="headerlink" href="#strict-mode" title="Permalink to this headline">¶</a></h2> -<p>By default CodeIgniter runs all transactions in Strict Mode.
