SQL Question - Implement With Global Tags (?)

This post was last updated for 190 days ago, and the information may already be changed

Hey guys,
I'd like to gather some Index page contain some dynamic tables of notes with custom fields.
I don't want to use Database feature because I rather the tables will update automatically.

I tried read this article: Some useful SQL snippets
In addition I tried to look in Query Plugin however I didn't understand how to implement it for my needs.

Example:

SELECT * FROM GLOBALTAGS 
WHERE GLOBALTAGS = Tools
Fields Page_name, GLOBALTAG, ANOTHER_GLOBALTAG_NAME
Groupby ANOTHER_GLOBALTAG_NAME

It seems there is only 2 tables (?): blocks/attributes.
Is there more? where can I read more about SQL in SiYuan? If anyone could help with implement example for my query it could be great.

Thanks ahead for all your wonderful work :)

      You can refer to this, although it is in Chinese, it should be well understood using web translation software: https://docs.siyuan-note.club/zh-Hans/reference/database/table.html

      Regarding the query plugin, which specific plugin are you referring to? It seems like there are several query plugins in SiYuan.

      Hey, I watch the docs you provide and the closest SQL query I succeed to make is: `

      SELECT * FROM blocks WHERE tag LIKE'%Cyber%' LIMIT 2

      I want to implement 2 queries:

      1. show list of only the doc's names with link to them with that belong for a specific tag.

      2. table contains doc's names (lets say for the example that every doc is a tool and those tools are subdocs in doc named "Tools"). with the field of the tool type (it'll be a tag)
        example:

        doc name tool (tag)
        [[Leonardo AI]] AI , IMG
        [[Github Coo-pilot]] AI , Code

        I download this query widget but I don't understand how to use it:

      This matter involves advanced SQLite queries, which are not as straightforward as they may seem. Here is a feasible example:

      SELECT '[\[' || doc.content || '\]](siyuan://blocks/' || tag.id || ')' AS __1____pre__title, 
tag.tag AS __2____pre__tag
FROM blocks AS doc, 
    (SELECT *
    FROM blocks
    WHERE tag LIKE "%Cyber%" ) AS tag
WHERE doc.id = tag.root_id

      If you need to write similar content on your own, you must understand the functions of subqueries and join queries in SQL queries.
