You can get idea from this example: Suppose you want to add user wise seven days data It should have unique value for userid and day like <pre><code>UNIQUE KEY `seven_day` (`userid`,`day`) </code></pre> Here is the table <pre><code>CREATE TABLE `table_name` ( `userid` char(4) NOT NULL, `day` char(3) NOT NULL, `open` char(5) NOT NULL, `close` char(5) NOT NULL, UNIQUE KEY `seven_day` (`userid`,`day`) ); </code></pre> And your query will be <pre><code>INSERT INTO table_name (userid,day,open,close) VALUES ('val1', 'val2','val3','val4') ON DUPLICATE KEY UPDATE open='val3', close='val4'; </code></pre> Example: <pre><code><?php //If your data is $data= array( 'sat'=>array("userid"=>"1001", "open"=>"01.01", "close"=>"11.01"), 'sun'=>array("userid"=>"1001", "open"=>"02.01", "close"=>"22.01"), 'sat'=>array("userid"=>"1001", "open"=>"03.01", "close"=>"33.01"), 'mon'=>array("userid"=>"1002", "open"=>"08.01", "close"=>"08.01"), 'mon'=>array("userid"=>"1002", "open"=>"07.01", "close"=>"07.01") ); //If you query this in a loop //$conn = mysql_connect("localhost","root",""); //mysql_select_db("test", $conn); foreach($data as $day=>$info) { $sql = "INSERT INTO table_name (userid,day,open,close) VALUES ('$info[userid]', '$day','$info[open]','$info[close]') ON DUPLICATE KEY UPDATE open='$info[open]', close='$info[close]'"; mysql_query($sql); } ?> </code></pre> Your data will be in table: <pre><code>+--------+-----+-------+-------+ | userid | day | open | close | +--------+-----+-------+-------+ | 1001 | sat | 03.01 | 33.01 | | 1001 | sun | 02.01 | 22.01 | | 1002 | mon | 07.01 | 07.01 | +--------+-----+-------+-------+ </code></pre>

Guidance

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.
