Edit in phpMyAdmin?

Hey,
I’m savvy but not amazing and new to phpMyAdmin and SQL.
My goal is to classify a number (all, actually) of my posts as private.
When in the wp_posts table, the relevant field is post_status. I can do a search and sort by this field, but what I want to do is change the values of the rows to set them to have a specific value (‘private’ from ‘publish’).

Anyone know how? I’m sure it’s simple but I’m green…
