Parameterized queries

This post was last updated for 206 days ago, and the information may already be changed

Hello,

I would like to be able to use an attribute of the parent block when writing an SQL query in an embed block. For the sake of example, consider I am in the document Trip to the Moon​ and I want to make a query that collects links to it. I would write

select b.* from blocks as b where b.content like "%trip to the moon%" order by updated desc

But I am already in Trip to the Moon​ (a document or a parent block with that name), so ideally I would like to grab the current document's title/name. I would like to replace the literal string "%trip to the moon%"​ with something like :parent.title​. How can I achieve this?

      In addition, the embedding blocks of the ontology support JS.You can use plugins to enhance embedded block queries.

      Hi again,

      I am wondering if using Javascript in the embed block could help here. Because I only get a partial translation and I don't know JS, I don't follow much of what is discussed in the feature request with issue number 9648, proposed by @frostime

      @frostime -- wout be possible to dynamically acquire metadata from the environment (current notebook/doc, preceding block, enclosing superblock) for use in a query by using the new //!js embed functionality?
