    <p>Please assist me on this one. I have two DB's, one keeps track of user and system activities and the other keeps track of only user activities. The purpose of the codes below is to first of all retreive all tables from the second DB. These tables have the following columns:</p> <p>(id |date |debit |credit |number |description |accounttype |company_id)</p> <p>The idea is to retrieve all tables and only their |debit|credit| columns. Already these fields (|debit|credit|) have some values in them. After retrieval, I should be able to update or if possible do a new insertion to any or all the tables that have been retrieved from the DB.</p> <p>Below are the codes I've written. It retrieves alright but can't do an insertion or update. Please assist me</p> <p>The same page calls itself.</p> <pre><code>//Connection and Extraction from DB //DB Connection exists //SQL Query $sql = "show tables from $companyname"; $results = mysql_query($sql) or die(mysql_error()); $count = 1; while($row = mysql_fetch_array($results)) { $results2 = mysql_query("SELECT * FROM `$row[0]` LIMIT 1") or die('Error'.mysql_error()); while($row2 = mysql_fetch_array($results2)) { $debit = $row2['debit']; $credit = $row2['credit']; echo "&lt;tr&gt;&lt;td&gt;$count. &lt;/td&gt;&lt;td width='30%'&gt;".ucwords($row[0])."&lt;/td&gt;&lt;td width='30%'&gt; &lt;input type='text' name='debit' value='$debit' align='right'&gt;&lt;/td&gt; &lt;td width='30%'&gt;&lt;input type='text' name='credit' value='$credit' align='right'&gt;&lt;/td&gt;&lt;/tr&gt;"; } $count++; } //Insertion into DB if(isset($_POST['submit'])) { //SQL Query $sql3 = "show tables from $companyname"; $results3 = mysql_query($sql3) or die(mysql_error()); $count = 1; while($row3 = mysql_fetch_array($results3)) { $results4 = mysql_query("SELECT * FROM `$row3[0]` LIMIT 1") or die('Error '.mysql_error()); $debit = $_POST['debit']; $credit = $_POST['credit']; while($row4 = mysql_fetch_array($results4)) { $query = mysql_query("UPDATE `$row3[0]` SET `debit`= '$row4[debit]' , `credit`= '$row4[credit]' WHERE `id`=`$row4[id]`"); echo "UPDATE `$row3[0]` SET `debit`= '$row4[debit]' , `credit`= '$row4[credit]' WHERE `id`=`$row4[id]` &lt;br&gt;"; echo $num; } $count++; } } </code></pre>

    2. COThank you for your quick response. The 1st schema contains a table that keeps record of a particular activity. This tables' PK is a FK in all the tables in the 2nd schema.

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.
