用于检查 WooCommerce 中的product_type 的 SQL 查询

我想通过以下方式过滤 WooCommerce 中的产品简单或可变的产品通过MySQL；但我找不到 WooCommerce 如何存储数据并在数据库中区分它们。

我想要一个 MySQL 查询来列出所有简单和可变产品；我不需要任何 PHP 代码。

就像是：

SELECT * FROM wp_posts WHERE post_type = 'product' AND product_type = 'simple';

MySQL 查询列出所有简单的产品:

SELECT
    posts.ID,
    posts.post_title,
    posts.post_author,
    posts.post_date,
    posts.post_date_gmt,
    posts.post_content,
    posts.post_excerpt,
    posts.post_status,
    posts.comment_status,
    posts.ping_status,
    posts.post_password,
    posts.post_name,
    posts.to_ping,
    posts.pinged,
    posts.post_modified,
    posts.post_modified_gmt,
    posts.post_content_filtered,
    posts.post_parent,
    posts.guid,
    posts.menu_order,
    posts.post_type,
    posts.post_mime_type,
    posts.comment_count
FROM
    wp_posts AS posts
INNER JOIN wp_term_relationships AS term_relationships ON posts.ID = term_relationships.object_id
INNER JOIN wp_term_taxonomy AS term_taxonomy ON term_relationships.term_taxonomy_id = term_taxonomy.term_taxonomy_id
INNER JOIN wp_terms AS terms ON term_taxonomy.term_id = terms.term_id
WHERE
    term_taxonomy.taxonomy = 'product_type'
AND terms.slug = 'simple'
AND posts.post_type = 'product';

只需更换simple from AND terms.slug = 'simple'与variable得到所有可变产品;

我已经测试了这个 SQL 查询，它显示了正确的结果。

希望这可以帮助！
