How should I write a select statement with optional filter parameter that may reference other table

Hi @samwalker. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave: ---------------------- In Refine, you can use the useSelect hook to write a select statement with optional filter parameters. Here's an example from the knowledge sources:

const { queryResult } = useSelect({
    resource: 'product',
    filters: [
      {
        field: 'is_deleted',
        operator: 'eq',
        value: false,
      },
    ],
});

const { queryResult } = useSelect({
    resource: 'product',
    filters: [
      {
        field: 'is_deleted',
        operator: 'eq',
        value: false,
      },
    ],
});

In this example, the useSelect hook is used to select data from the 'product' resource. The filters option is used to specify filter parameters. In this case, it's filtering for products where the 'is_deleted' field is equal to 'false'. If you want to reference another table, you would need to set up a relationship between the tables in your database. For example, in a Supabase database, you can add foreign key relationships to link tables together. Once the relationship is set up, you can reference the other table in your select statement. Here's an example of how to add a foreign key relationship in Supabase: 1. Go to a table, right click the column you wish to add a foreign key for 2. Select 'edit column' 3. Select 'Add foreign key relation' 4. Select the table and column to make a foreign key for 5. Click save After setting up the relationship, you can reference the other table in your select statement. However, the exact syntax for doing this will depend on the specifics of your database and the data provider you're using with Refine. For more detailed information, you can refer to the Refine documentation (https://refine.dev/docs) and the Supabase documentation (https://supabase.io/).
