Hi @edgy maple. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave:
Astro DB allows you to store a list of items in a column using the column.json() type. This type allows you to store arbitrary JSON blobs, which can be an array of items. Here's an example of how you can define a column to store a list of items:
import { defineTable, column } from 'astro:db';
const Comment = defineTable({
columns: {
// Other columns...
items: column.json(),
}
});
In this example, the items column can store a JSON array of items. When you insert data into this table, you can provide a JSON array for the items column.
Please note that the data stored in a column.json() type is parsed as stringified JSON for data storage. This means that you'll need to parse the JSON when you retrieve the data from the database.
For more details, you can refer to the Astro DB documentation (https://docs.astro.build/en/guides/integrations-guide/db/#table-configuration-reference).
Note: you can ask me a follow up question by @ mentioning me again :speech_balloon:

@modern peak Is it possible to query based on the values in said json?

Let me check the knowledge base for you. One moment! :books:
Yes, it is possible to query based on the values in the JSON column using the like() operator provided by Astro DB. Here's an example of how you can do this:
import { db, Comment, like } from 'astro:db';
const comments = await db.select().from(Comment).where(like(Comment.items, '%value%'));
In this example, the like() operator is used to check if a value is present within the items JSON column. The %value% is a placeholder for the value you're searching for.
Please note that the like() operator checks if a string is present within the column. This means that it may not work as expected if you're searching for complex JSON structures.
