Update internal links only

I’m still wondering if this plugin will be able to help me.

I need to update all internal links only to open in the same tab. Over the years many have been set to new tab, which was a rookie mistake that needs fixing, only we don’t know exactly how many or where they are. I’m not in the mood to go through countless links in over 100 posts to check one by one.

So in other words, all internal links that have target=”blank’ need to have that removed. External links will remain opening in new tab.

If this plugin can’t help with this, what phpMyAdmin command can I run? I’ve been looking (Googling), but haven’t found anything, yet. I’m still looking….
