我认为一个简单的版本可能是这样的：

SELECT 
    t.user_id,
    CURRENT_TIMESTAMP AS granted_at,
    p.id AS post_id
FROM topics t
  JOIN posts p ON p.topic_id = t.id AND p.post_number = 1
WHERE t.posts_count >= 100
  AND t.archetype = 'regular'
  AND t.deleted_at ISNULL
  AND t.user_id > 0

使用 t.post_counts 目前还将包括小的操作帖子（已关闭、未列出等），因此这取决于您希望它有多准确。

您可以通过在查询中计算“符合条件”的帖子来使其更具体。例如：

SELECT 
    t.user_id,
    CURRENT_TIMESTAMP AS granted_at,
    p.id AS post_id
FROM topics t
  JOIN posts p ON p.topic_id = t.id AND p.post_number = 1
WHERE t.id IN ( 
    SELECT 
        p.topic_id
    FROM posts p
      JOIN topics t ON t.id = p.topic_id
    WHERE t.archetype = 'regular'
      AND t.deleted_at IS NULL
      AND p.deleted_at IS NULL
      AND p.post_number <> 1
      AND p.post_type = 1
      AND p.hidden IS FALSE
     GROUP BY 1
     HAVING COUNT(*) >= 100
     )
