    <p>I tried this as a test purpose. And I don't know why is this happening. That's I need help from the experts. Thanks.</p> <p>Lets assume that we have a database and we have established connection with the database. Let's assume there is a table named <code>table</code>. Inside the table there are two columns- id and name. there are 5 rows of data in the table. Table structure is</p> <pre><code>| id | name | --------------- | 1 | name1 | | 2 | name2 | | 3 | name3 | | 4 | name4 | | 5 | name5 | </code></pre> <p>Now my code goes here-</p> <pre><code> &lt;?php mysql_connect("localhost","root","") or die(mysql_error()); mysql_select_db("test") or die(mysql_error()); $result = mysql_query("SELECT * FROM `table`"); /* let's store this value in two different variables. */ $result1 = $result; $result2 = $result; /* let's perform mysql_fetch_array() and mysql_fetch_row() functions */ $result22 = mysql_fetch_row($result); var_dump($result22); $result11 = mysql_fetch_array($result); var_dump($result11); ?&gt; </code></pre> <p>it results :</p> <pre><code>array 0 =&gt; string '1' (length=1) 1 =&gt; string 'name1' (length=5) array 0 =&gt; string '2' (length=1) 'id' =&gt; string '2' (length=1) 1 =&gt; string 'name2' (length=5) 'name' =&gt; string 'name2' (length=5) </code></pre> <p>If i alter the order of the functions it results :</p> <pre><code>array 0 =&gt; string '1' (length=1) 'id' =&gt; string '1' (length=1) 1 =&gt; string 'name1' (length=5) 'name' =&gt; string 'name1' (length=5) array 0 =&gt; string '2' (length=1) 1 =&gt; string 'name2' (length=5) </code></pre> <p>It seems that when I perform a function upon the result of mysql_query, that function simply removes the first row from the result even if it is stored in other variable before calling the function. </p> <p>If i add a condition WHERE <code>id</code> = 1 then the second function returns false, like:</p> <pre><code>array 0 =&gt; string '1' (length=1) 'id' =&gt; string '1' (length=1) 1 =&gt; string 'name1' (length=5) 'name' =&gt; string 'name1' (length=5) boolean false </code></pre> <p>Why is this happening? Thanks in advance.</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
