From wordpress 3.0 version wordpress launched the feature called featured image. Many new wordpress themes are compatible with new wordpress version. So using or choosing the image as featured image for post is another manual work we need to do.
Many old wordpress website holder or blogger is having issue with this functionality. What they want is when they create the post they haven’t set the featured image, but they would like the featured image to default to the image that has been included in the post.
Some wordpress always use the first image as featured image but old post was not updated with featured image. They need to do manual work to set the featured image. I also faced same issue.
After doing some R&D I found the solution. If you want to set the your posts first image as featured image then use my following code.
For using the code you need to open your mysql database command prompt or phpmysqladmin program and select your wordpress database and execute the following query in that.
insert into wp_postmeta (meta_value, meta_key, post_id) select DISTINCT(ID), post_type , post_parent from wp_psts where post_type= 'attachment' and post_parent !=0 and post_status='inherit';<br /><br />update wp_postmeta set meta_key = '_thumbnail_id' where meta_key='attachment'
Using above sql query you will be able to set the featured image to your old and new post from post content. If you are having any issues with using this sql then write to me.

When I checked my database I saw the all the my attachments are listed in post table but images are not displaying. All the places I only saw the wp-includes/images/crystal/default.png image.
I did spend one hour googled for solving the issue but I did not find any solution for this. Than again I checked my Folder permissions and images files but I found all things are perfect.
Then I checked my database and I found the issue. in wp_posts table ->post_mime_type column one entry was missing. After seeing that issue I fixed the issue.
I used the following mysql quires using myphpadmin tool.
[viral-lock message=”Solution code is Hidden! It’s Visible for Users who Liked/Shared This article on Facebook or Twitter or Google+. Like or Tweet this article to reveal the content.”]
Update wp_posts set post_mime_type='image/jpg' WHERE guid like '%jpg%'
Update wp_posts set post_mime_type='image/jepg' WHERE guid like '%jepg%'
Update wp_posts set post_mime_type='image/png' WHERE guid like '%png%'
Update wp_posts set post_mime_type='image/gif' WHERE guid like '%gif%'
[/viral-lock]
After using above query I checked the my media library. I am able to see my all images in media library.
My advise to you is first take backup of your database and then use above mysql quires. Then use the above queries.
If you are imported post from other website then use following commands also.
UPDATE wp_posts SET post_content = REPLACE(post_content, 'NEW-DOMAIN-NAME', 'files/');
UPDATE wp_posts SET post_excerpt = REPLACE(post_excerpt, 'NEW-DOMAIN-NAME', 'OLD-DOMAIN-NAME');
UPDATE wp_posts SET guid = REPLACE(guid, 'NEW-DOMAIN-NAME', 'OLD-DOMAIN-NAME');
Above quires will change the domain location of file.
