Why i use useSelector cannot get data?

[tytom2003]

i used useSelector, but it can't get data.
My program part:

const ordermgmtAdapter = createEntityAdapter()

const initialState = ordermgmtAdapter.getInitialState()

export const {
useGetOrdersQuery,
useUpdateOrderMutation,
} = OrderMgmtApiSlice

export const selectOrderResult = OrderMgmtApiSlice.endpoints.getOrders.select();

const selectOrdersData = createSelector(
selectOrderResult,
orderResult => orderResult.data
)

export const {
selectAll: selectAllOrders,
} = ordermgmtAdapter.getSelectors(state => selectOrdersData(state) ?? initialState)

in other compoent, i used const Orders = useSelector(selectAllOrders); to get data. It cannot get data,
but i used below. orderdata can get data.

const {
data: orderdata,
isSuccess,
isLoading,
isError,
error,
refetch
} = useGetOrderQuery()

my progam using package:
"@reduxjs/toolkit": "^2.2.8",
"react-redux": "^9.1.2",
"redux-persist": "^6.0.0",
nodejs: 20.11.1

useSelector only selects state already in store, it won't kick off any fetching processes. you should continue to use the useQuery hook for that.

if i want to use useUpdateOrderMutation to update data, it can't view new update data at once?
Thank you very much.

Your choices for making sure the query updates after a mutation are automated refetching using tags, or manual cache updates.

i solve auto update data.
