Supabase：使用连接和逻辑“或”过滤数据

Question

I'm using Supabase as a database and trying to implement a full-text search.

My example setup is quite simple, I have two tables:

items

+----+-----------+-----------------+
| id | name      | manufacturer_id |
+----+-----------+-----------------+
| 1  | Notebook  | 1               |
+----+-----------+-----------------+
| 2  | Mouse     | 2               |
+----+-----------+-----------------+

manufacturers

+----+-----------+
| id | name      |
+----+-----------+
| 1  | Apple     |
+----+-----------+
| 2  | Microsoft |
+----+-----------+

My goal: search for item names or manufacturer names and always receive the respective items . Searching for 'Apple' would return all items whose manufacturers name contain this phrase. Searching for 'Notebook' would return all items with this name.

( I simplified this example by using exact matches because this is not the problem I'm stuck with ).

My current approach is the following:

let keyword = 'Apple';

supabase
  .from('items')
  .select('*, manufacturers!inner(*)')
  .or(`name.eq.${term}`)
  .or(`name.eq.${term}`, { foreignTable: 'manufacturers' })

Although this query does not return anything.

If I remove .or('name.eq.${term}') it return the correct item. Same if I remove the second .or() and use an item name as my keyword.

I simply can't find a way to combine two OR operators. I also tried multiple filter() queries but was not successfully.

EDIT: The (working) SQL syntax would be the following:

SELECT * FROM items 
   JOIN manufacturers ON items.manufacturer_id = manufacturers.id
   WHERE items.name = 'Apple' OR manufacturers.name = 'Apple'

Does anyone have an approach on how to do that with the Supabase JavaScript SDK? Thank you in advance!

Answer 1

You can't OR combine a foreign table( manufacturers ) condition with a parent table( items ) condition directly through the JS SDK.

(More details about why here )

However you can create a function wrapping your query and use rpc to get it:
