How to do pagination in wordpress page that contain mysql query? - php

Question

I have one wordpress page in that I want to add pagination code. Because of mysql query the data in page is dynamic so I searched on google this but as I'm new in wordpress don't know what is WP-PageNavi plugin and how to use it. Please suggest me how to use it or any simpler way to do this.
My code is:
<table id="myTable" class="table table-striped" style="width:200% !important" name="myTab">
<thead>
<tr>
<th>Sr.No</th>
<th>Name</th>
<th>College Name </th>
<th>Passout Year</th>
<th>Branch</th>
<th>Email ID </th>
<th> Phone No.</th>
</tr>
</thead>
<tbody>
[hi_php]
mysql_connect("localhost","root","");
mysql_select_db("wp");
$query = mysql_query("select id,value from wp_crf_entries where value like '%Alumini%' ")or die(mysql_error());
while ($row=mysql_fetch_array($query))
{
$users = maybe_unserialize($row['value']);
echo "<tr><td>";
echo $row['id'];
echo "</td><td>";
echo $users['firstname_1'];
echo " ".$users['lastname_2'] ."</br>";
echo "</td><td>";
echo $users['collegename_4'] ;
echo "</td><td>";
echo $users['passoutyear_7'] ;
echo "</td><td>";
echo $users['branch_8'] ;
echo "</td><td>";
echo $users['user_email'] ;
echo "</td><td>";
echo $users['contactno_10'] ;
echo "</td></tr>";
echo "<tr><td>";
}
[/hi_php]
</tbody>
