Properties

Property	Type	Description	Overrides
`data`	`undefined`	`undefined`, since the query has no data yet.	`QueryObserverBaseResult`.`data`
`dataUpdatedAt`	`number`	The timestamp for when the query most recently returned the `status` as `"success"`.	-
`error`	`null`	`null`, since the query isn't in the `error` state.	`QueryObserverBaseResult`.`error`
`errorUpdateCount`	`number`	The sum of all errors.	-
`errorUpdatedAt`	`number`	The timestamp for when the query most recently returned the `status` as `"error"`.	-
`failureCount`	`number`	The failure count for the query. - Incremented every time the query fails. - Reset to `0` when the query succeeds.	-
`failureReason`	`TError` \| `null`	The failure reason for the query retry. - Reset to `null` when the query succeeds.	-
`fetchStatus`	`"fetching"` \| `"paused"` \| `"idle"`	The fetch status of the query. - `fetching`: Is `true` whenever the queryFn is executing, which includes initial `pending` as well as background refetch. - `paused`: The query wanted to fetch, but has been `paused`. - `idle`: The query is not fetching. - See Network Mode for more information.	-
`isEnabled`	`boolean`	`true` if this observer is enabled, `false` otherwise.	-
`isError`	`false`	`false`, since the query isn't in the `error` state.	`QueryObserverBaseResult`.`isError`
`isFetched`	`boolean`	Will be `true` if the query has been fetched.	-
`isFetchedAfterMount`	`boolean`	Will be `true` if the query has been fetched after the component mounted. - This property can be used to not show any previously cached data.	-
`isFetching`	`boolean`	A derived boolean from the `fetchStatus` variable, provided for convenience. - `true` whenever the `queryFn` is executing, which includes initial `pending` as well as background refetch.	-
~~`isInitialLoading`~~	`boolean`	Deprecated `isInitialLoading` is being deprecated in favor of `isLoading` and will be removed in the next major version.	-
`isLoading`	`boolean`	Is `true` whenever the first fetch for a query is in-flight. - Is the same as `isFetching && isPending`.	-
`isLoadingError`	`false`	`false`, since the query didn't fail while fetching for the first time.	`QueryObserverBaseResult`.`isLoadingError`
`isPaused`	`boolean`	A derived boolean from the `fetchStatus` variable, provided for convenience. - The query wanted to fetch, but has been `paused`.	-
`isPending`	`true`	`true`, since there's no cached data and no query attempt has finished yet.	`QueryObserverBaseResult`.`isPending`
`isPlaceholderData`	`false`	`false`, since the data shown isn't the `placeholderData`.	`QueryObserverBaseResult`.`isPlaceholderData`
`isRefetchError`	`false`	`false`, since the query didn't fail while refetching.	`QueryObserverBaseResult`.`isRefetchError`
`isRefetching`	`boolean`	Is `true` whenever a background refetch is in-flight, which does not include initial `pending`. - Is the same as `isFetching && !isPending`.	-
`isStale`	`boolean`	Will be `true` if the data in the cache is invalidated or if the data is older than the given `staleTime`.	-
`isSuccess`	`false`	`false`, since the query isn't in the `success` state.	`QueryObserverBaseResult`.`isSuccess`
`refetch`	(`options?`: `RefetchOptions`) => `Promise`<`QueryObserverResult`<`TData`, `TError`>>	A function to manually refetch the query.	-
`status`	`"pending"`	`'pending'`, since there's no cached data and no query attempt has finished yet.	`QueryObserverBaseResult`.`status`
