-<h1>Generating Query Results</h1>
-
-
-<p>There are several ways to generate query results:</p>
-
- <h2>result()</h2>
-
- <p>This function returns the query result as an array of <strong>objects</strong>, or <strong>FALSE</strong> on failure.
-
- Typically you'll use this in a foreach loop, like this:</p>
-
- <code>
- $query = $this->db->query("YOUR QUERY");<br />
- <br />
- foreach ($query->result() as $row)<br />
- {<br />
- echo $row->title;<br />
- echo $row->name;<br />
- echo $row->body;<br />
- }</code>
-
- <p>If you run queries that might <strong>not</strong> produce a result, you are encouraged to test the result first:</p>
-
- <code>
- $query = $this->db->query("YOUR QUERY");<br />
- <br />
- if ($query->num_rows() > 0)<br />
- {<br />
- foreach ($query->result() as $row)<br />
- {<br />
- echo $row->title;<br />
- echo $row->name;<br />
- echo $row->body;<br />
- }<br />
- }
- </code>
-
- <h2>result_array()</h2>
-
- <p>This function returns the query result as a pure array, or FALSE on failure. Typically you'll use this in a foreach loop, like this:</p>
- <code>
- $query = $this->db->query("YOUR QUERY");<br />
- <br />
- foreach ($query->result_array() as $row)<br />
- {<br />
- echo $row['title'];<br />
- echo $row['name'];<br />
- echo $row['body'];<br />
- }</code>
-
- <h2>result('array')</h2>
-
- <p>Identical to <dfn>$this->db->result_array()</dfn>.</p>
-
-
- <h2>row()</h2>
-
- <p>This function returns a single result row. If your query has more than one row, it returns only the first row.
- The result is returned as an <strong>object</strong>. Here's a usage example:</p>
- <code>
- $query = $this->db->query("YOUR QUERY");<br />
- <br />
- if ($query->num_rows() > 0)<br />
- {<br />
- $row = $query->row();
- <br /><br />
- echo $row->title;<br />
- echo $row->name;<br />
- echo $row->body;<br />
- }
- </code>
-
- <p>If you want a specific row returned you can submit the row number as a digit in the first parameter:
-
- <code>$row = $query->row(<dfn>5</dfn>);</code>
-
-
- <h2>row_array()</h2>
-
- <p>Identical to the above <var>row()</var> function, except it returns an array. Example:</p>
-
- <code>
- $query = $this->db->query("YOUR QUERY");<br />
- <br />
- if ($query->num_rows() > 0)<br />
- {<br />
- $row = $query->row_array();
- <br /><br />
- echo $row['title'];<br />
- echo $row['name'];<br />
- echo $row['body'];<br />
- }
- </code>
-
-
- <p>If you want a specific row returned you can submit the row number as a digit in the first parameter:
-
- <code>$row = $query->row_array(<dfn>5</dfn>);</code>
-
-
- <p>In addition, you can walk forward/backwards/first/last through your results using these variations:</p>
-
-<p>
- <strong>$row = $query->first_row()</strong><br />
- <strong>$row = $query->last_row()</strong><br />
- <strong>$row = $query->next_row()</strong><br />
- <strong>$row = $query->previous_row()</strong>
-</p>
-
-<p>By default they return an object unless you put the word "array" in the parameter:</p>
-
-<p>
- <strong>$row = $query->first_row('array')</strong><br />
- <strong>$row = $query->last_row('array')</strong><br />
- <strong>$row = $query->next_row('array')</strong><br />
- <strong>$row = $query->previous_row('array')</strong>
-</p>
-
-
-
-<h1><br />Result Helper Functions</h1>
-
-
-<h2>$query->num_rows()</h2>
-<p>The number of rows returned by the query. Note: In this example, <dfn>$query</dfn> is the variable that the query result object is assigned to:</p>
-
-<code>$query = $this->db->query('SELECT * FROM my_table');<br /><br />
-echo $query->num_rows();
-</code>
-
-<h2>$query->num_fields()</h2>
-<p>The number of FIELDS (columns) returned by the query. Make sure to call the function using your query result object:</p>
-
-<code>$query = $this->db->query('SELECT * FROM my_table');<br /><br />
-echo $query->num_fields();
-</code>
