我有一个这样的全文查询，它得到了我期望的结果

SELECT  id,'', 'blogs' as mytable,title, content, 
    MATCH(title) AGAINST('keywords*' IN BOOLEAN MODE) * 8 +
    MATCH(content) AGAINST('keywords*' IN BOOLEAN MODE) * 4
        as score FROM blogs WHERE archived = 'N' AND MATCH(title, content) 
            AGAINST('keywords*' IN BOOLEAN MODE)
             ORDER BY score DESC, id DESC

如果我搜索一个特定的关键字，我会得到一个 ID 为 4 的结果。问题是我需要一个额外的列，以便我可以搜索该 ID 以获取该 ID 的行位置。

如果我自己运行此查询，我会得到正确的结果，即 8

SELECT position FROM
(
   SELECT
   id, @rownum:=@rownum+1 position, archived
   FROM blogs, (SELECT @rownum:=0) r WHERE archived ='N'
   ORDER BY id DESC
)
AS position
WHERE id = 4

我想要做的是将这些查询合并到一个查询中，以便将第一个查询的 ID 传递到第二个查询的 WHERE 中，这样我的名为“位置”的附加列的值为 8

我试图结合查询，但这绝对是不对的

4

像这样的东西？

SELECT position FROM
(
   SELECT
   id, @rownum:=@rownum+1 position, archived
   FROM blogs, (SELECT @rownum:=0) r WHERE archived ='N'
   ORDER BY id DESC
)
AS position
WHERE id IN (SELECT id FROM(SELECT  id,'', 'blogs' as mytable,title, content, 
    MATCH(title) AGAINST('keywords*' IN BOOLEAN MODE) * 8 +
    MATCH(content) AGAINST('keywords*' IN BOOLEAN MODE) * 4
        as score FROM blogs WHERE archived = 'N' AND MATCH(title, content) 
            AGAINST('keywords*' IN BOOLEAN MODE)
             ORDER BY score DESC, id DESC)x)
