Question

This is my php code

<?php
if(isset($_GET['name']))
    {
        $var = $_GET['name'];
        $newvar =str_replace (" ", "", $var);
        $sql = "SELECT varpin, ABS( varpin - '".$newvar."' ) AS pin FROM tbladstore ORDER BY pin LIMIT 5";

    }
?>

Here name have value 682 031.In table varpin is stored as xxx xxx.Here i want to remove the space of varpin value when selecting using query.

That is after this step

 `$newvar =str_replace (" ", "", $var);`

the $newvar have the format xxxxxx.so i also need varpin is in this format for finding nearest values of a given pin number.How can i do this?

In db the varpin is in varchar type.I also need this field as only varachar not changed to other type.

You could use REPLACE(varpin, ' ', '') to get rid of all spaces in varpin column.

And then use CONVERT(value, DECIMAL) to make it into a numeric type.

CONVERT(REPLACE(varpin,' ',''), DECIMAL)
