What application are you using to view your MySQL DB? Many people use phpMyAdmin. What ever application you are using, make sure that you have first determined how many rows your wp_sitemeta table contains.

In my version of phpMyAdmin, it defaults to showing only 30 records at a time. So, if there are more than 30 rows in a given table, and you are not aware of that fact, it can be easy to assume that all available records are being displayed–even when there are buttons to advance to the next set or records. Of course, there are a few ways to change the default value so that more (or all) records are showed.
