    <p>First of all, <code>mysql_query</code> is deprecated as I know.</p> <p>Try learning <a href="http://www.phpro.org/tutorials/Introduction-to-PHP-PDO.html" rel="nofollow">PDO</a>. It is safer, and other advantages I guess.</p> <p>Moreover, what your example is doing is, write <strong>into</strong> the mysql query, which is probably wrong. In the end, you will have a mysql query like :</p> <pre><code>insert into tablename set Reg_no = 'something' while(fieldcount&lt;=10) { echo something else } </code></pre> <p>etc. , which does not make sense in MySQL. MySQL will not understand what <code>echo</code> is.</p> <p>MySQL expects a query like <code>"INSERT INTO tablename(fieldname) VALUES ('the_value')"</code>;</p> <p>So I guess what you are trying to do is run a mysql query, and echo something in the screen, like this:</p> <pre><code>$pdo-&gt;query("insert into tablename (field1,field2) values ('value1' , 'value2')"); while(fieldcount&lt;=10) { echo "something"; } </code></pre> <p>and please note that above example is also not safe, if you are concerned about mysql injection.</p> <p>So, my advice is, also learn about <a href="http://pressedweb.com/tutorials/pdo-baby-steps-prepared-statements/" rel="nofollow">prepared statements</a>.</p> <h2>Edit:</h2> <p>If you want to run mysql queries in a loop, you can do something like this:</p> <pre><code>&lt;?php for($i=0 ; $i &lt; 10 ; $i++) { $thefield = "field".$i; // construct your field name $thevalue=$i; // construct your value. I guess this is where your $_REQUEST variables go. $pdo-&gt;query("insert into tablename($thefield) VALUES('$thevalue')"); // then run the necessary mysql query. echo "i inserted $thevalue for the field $thefield"; } // and of course, for this case, you may not need a loop. You can insert multiple values at once, like this: $pdo-&gt;query("insert into tablename (field1,field2,and_any_other_field) values ('value1' , 'value2' , 'value_for_other_field')"); // etc. ?&gt; </code></pre> <p>for example.</p>

    1. COYes you are right that MYSQL does not understand what is echo and what is while but I want to know how can I use it within mysql query. I want each and every field value to be inserted by use of while loop.

Querying!

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.
