Select syntax for supabase

Pplain-purple7/6/2023
how do you do multiple joins with select on useTable when using supabase? can't find anything on transforming supabase API examples to what select uses

Hi @fuddlesworth. 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 handle relational data using the useMany hook and filter <Table> by categories with the help of useSelect [^1^]. When using Supabase as your data provider, you can pass a select value in the meta object to perform relational database operations [^2^]. For example, if you have a posts -> categories relationship and you want to get the title data from the categories table and display it on the List page, you can do something like this:
const { tableProps, sorter } = useTable<IPost>({
resource: "posts",
meta: {
select: "*, categories(title)",
},
});
const { tableProps, sorter } = useTable<IPost>({
resource: "posts",
meta: {
select: "*, categories(title)",
},
});
[^2^] In this example, useList, useOne, useMany hooks are using Supabase select property internally. So you can pass parameters to the Supbase select method using meta property [^2^]. Please note that the select value in the meta object is using Supabase select property internally, which means you can use the same syntax as you would in a Supabase API call. For more complex joins or queries, you might need to adjust the select value accordingly. If you need more specific help, please provide more details about your data structure and the exact query you're trying to perform.

@kapa.ai what's an example of using count with select
Kkapa.ai7/6/2023
Let me check the knowledge base for you. One moment! :books: ---------------------- In refine, when using Supabase as your data provider, you can use the count option with select to get the exact count of rows in a table. This is useful for pagination purposes. Here's an example of how you can use it:
const query = supabaseClient
.from(resource)
.select(metaData?.select ?? "*", {
count: "exact",
});
const query = supabaseClient
.from(resource)
.select(metaData?.select ?? "*", {
count: "exact",
});
[^3^] In this example, supabaseClient.from(resource).select() is used to select data from a specific resource. The count: "exact" option is passed to the select method to get the exact count of rows. Please note that this is a part of a larger data provider function and might need to be adjusted according to your specific use case.

@kapa.ai how do i use select to select Rooms joining on project_id and from Windows joining on room_id
Kkapa.ai7/6/2023
Let me check the knowledge base for you. One moment! :books: ---------------------- In refine, when using Supabase as your data provider, you can use the select value in the meta object to perform relational database operations. However, the provided extracts do not contain a specific example of joining Rooms on project_id and Windows on room_id. Here's a general example of how you might structure your select statement:
const { tableProps, sorter } = useTable<IRoom>({
resource: "rooms",
meta: {
select: "*, projects(*), windows(*)",
},
});
const { tableProps, sorter } = useTable<IRoom>({
resource: "rooms",
meta: {
select: "*, projects(*), windows(*)",
},
});
In this example, rooms is the main resource, and we're joining on projects and windows. The (*) after each resource indicates that we want to select all fields from those resources. You would replace projects and windows with the actual names of your resources. Please note that this is a general example and might need to be adjusted according to your specific use case and data structure. For more complex joins or queries, you might need to adjust the select value accordingly. For more information, you can refer to the Supabase documentation (https://supabase.io/docs/reference/javascript/select) on how to structure select statements for joins.
