Question

I want to create a dynamic page in WP theme so that when I pass a letter from ‘A-Z’ it will display all the posts with the title starting from that letter.
Can you please tell me how to proceed?

If you are using themes and getting the index key via a query parameter then you can create a new custom theme file and add the following code to get the list of posts.

$thePostIdArray = null;
    $indexkey = $_GET['indexkey']; 
    if ($indexkey!=null){
        $querystr = "
            SELECT wposts.ID 
            FROM $wpdb->posts wposts
            WHERE UPPER(wposts.post_title) like '".$indexkey."%' 
            AND wposts.post_status = 'publish' 
            AND wposts.post_type = 'post' 
            ORDER BY wposts.post_title ASC
         ";
        $thePostArray = $wpdb->get_results($querystr); 
        $i = 0;
        foreach ($thePostArray as $currentPost){
            $thePostIdArray[$i] = $currentPost->ID;
            $i++;
        }

After that just just a matter of going through the post array and displaying them.
