HI @makoto_matsumot,
First thing, Magento 2 use EAV models for Product data.
Product data are saved in multiple tables.
catalog_product_entity
catalog_product_entity_int
catalog_product_entity_varchar
catalog_product_entity_text
catalog_product_entity_decimal
catalog_product_entity_datetime
It is not straight forward to write mysql to get product data.
I always recommend to use Magento models or Magento API to get data.
BTW you can get data using below mysql query.
SELECT e.entity_id AS 'id',
v1.value AS 'name',
e.sku,
d1.value AS 'price',
t1.value AS 'short_description',
t2.value AS 'description',
v2.value AS 'image',
v3.value AS 'thumbnail',
mg.value AS 'media_gallery',
cids.category_ids AS 'category_ids',
cids.category_names AS 'category_names'
FROM catalog_product_entity e
LEFT JOIN catalog_product_entity_varchar v1 ON e.entity_id = v1.entity_id
AND v1.store_id = 0
AND v1.attribute_id =
(SELECT attribute_id
FROM eav_attribute
WHERE attribute_code = 'name'
AND entity_type_id =
(SELECT entity_type_id

LEFT JOIN catalog_product_entity_text t1 ON e.entity_id = t1.entity_id
AND t1.store_id = 0

I hope it will help you!
