Using the database to inspect EAV-based entity types can be a real pain in the ass, so here are a bunch of queries that let you inspect some popular EAV entity types easily. This practice can be applied to any EAV entity type, however as there are about 25 of them, I decided to just list the popular ones, enjoy.
Output example (shortened):
|----------------------------------+----------+----------+---------------------|
| attribute_code | type | store_id | value |
|----------------------------------+----------+----------+---------------------|
| meta_title | varchar | 0 | Sofas and Armchairs |
| name | varchar | 0 | Sofas & Armchairs |
| page_layout | varchar | 0 | NULL |
| sitemap_include | int | 0 | 1 |
| url_key | varchar | 0 | sofas-and-armchairs |
|----------------------------------+----------+----------+---------------------|

Note - these queries may not work in some graphical query tools such as MySQL Query Browser due to having two queries (one to set the variable, and another to run the query). If you want to use the queries in these tools, remove the SET statement and replace all occurrences of @entity_id with the entity_id you wish to fetch.
