For example, you have a table named table1 which has the structure like this:

mysql> DESCRIBE `table1`;
+-------------+-------------+------+-----+---------+-------+
| Field       | Type        | Null | Key | Default | Extra |
+-------------+-------------+------+-----+---------+-------+
| code        | char(2)     | YES  |     |         |       |
| description | varchar(50) | YES  |     | NULL    |       |
+-------------+-------------+------+-----+---------+-------+

and it has the duplicate records as following:

mysql> select * from table1;
+------+-------------+
| code | description |
+------+-------------+
| 1    | One         |
| 1    | One         |
| 2    | Two         |
| 2    | Two         |
| 3    | Three       |
| 3    | Three       |
| 3    | Three       |
| 4    | Four        |
| 4    | Four        |
| 4    | Four        |
| 4    | Four        |
| 5    | Five        |
| 5    | Five        |
| 5    | Five        |
| 5    | Five        |
| 5    | Five        |
+------+-------------+

Let’s say, you want to delete and leave only one record from each the duplicate records. So the results become like this:

+------+-------------+
| code | description |
+------+-------------+
| 1    | One         |
| 2    | Two         |
| 3    | Three       |
| 4    | Four        |
| 5    | Five        |
+------+-------------+

So, in order to get that results, copy only the table structure of table1 to (for example) table1_copy using the following SQL statement:

mysql> CREATE TABLE `table1_copy` LIKE `table1`;

Afterwards, copy or insert only one record of the duplicate records from table1 into the table1_copy using the following SQL statement:

INSERT INTO table1_copy
SELECT DISTINCT * FROM table1;

Voila… here is the result:

mysql> SELECT * FROM table1_copy;
+------+-------------+
| code | description |
+------+-------------+
| 1    | One         |
| 2    | Two         |
| 3    | Three       |
| 4    | Four        |
| 5    | Five        |
+------+-------------+

Ups, don’t forget to remove the table1 table (assuming all the steps above goes smoothly):

DROP TABLE IF EXISTS `table1`;

and then rename the destination table to the original one:

RENAME TABLE `table1_copy` TO `table1`;

It’s very easy, isn’t?

Suppose we have a table named mytable which has these following records inside:

+----+-------+
| id | name  |
+----+-------+
|  1 | One   |
|  2 | One   |
|  3 | Two   |
|  4 | Two   |
|  5 | Two   |
|  6 | Three |
|  7 | Three |
|  8 | Three |
|  9 | Three |
| 10 | Four  |
| 11 | Five  |
+----+-------+
11 rows in set (0.00 sec)

and you want to display which one has the duplicate content in the name filed become like this:

+-------+---------+
| name  | howmany |
+-------+---------+
| Three |       4 |
| Two   |       3 |
| One   |       2 |
+-------+---------+
3 rows in set (0.00 sec)

In the other words, we will display the value in name field which have more than one records, whereas, the records which do not the duplicate content, will be avoided (in this case the record which have the value in field name-nya: Four and Five).

Well, here is the SQL script to do make it came true:

SELECT name, COUNT(name) AS howmany 
FROM `my_table`
GROUP BY name 
HAVING howmany > 1
ORDER BY howmany DESC;

1. Open your \include\client\tickets.inc.php file, and find this code:

   75	<div style="margin: 10px 0 60px 0;">

   after the last line of that code above, please insert this following code:

   76 77 78 79 80 81 82 83

   <script language="JavaScript"> function submitForm() { param=document.form.limit.options[document.form.limit.selectedIndex].value; url="?limit="+param+""; location.href=url; } </script> <form name="form">

   Find again this code:

   86	<td width="60%" class="msg"><?=$showing?>&nbsp;&nbsp;<?=$results_type?>

   after that line, please insert this following code:

   87 88 89 90 91 92 93 94 95

   &nbsp;Limit: <select name='limit' onChange="submitForm(this.form)"> <?php for ($x = 5; $x <= 50; $x += 5) { ?> <option value="<?=$x?>" <?=($pagelimit==$x )?'selected':''?>><?=$x?></option> <?php } ?> </select> &nbsp;&nbsp;

   Find again this code:

   104

   </table>

   after that line, please insert this following code:

   105

   </form>

That’s all. Now client can choose the page limit when displaying the ticket list from My Ticket page.

In this example below, I used state data type that currently exists in wp_pod_tbl_state table.

I hope this is helpful.
