Hi, when `with` is executed for a DB that is gotten from the original DB by calling `as-of` function then the execution of `with` returns a map where the database available by key `:db-after` still points to the original DB. I mean when I use `after db` to get an updated entity I still see old data
The script to reproduce the issue:
```auto
(require '[datomic.api :as d])
(d/create-database "datomic:dev://localhost:4334/test?password=datomic")
(def conn (d/connect "datomic:dev://localhost:4334/test?password=datomic"))
(def user-schema [
{
:db/ident :User/name
:db/valueType :db.type/string
:db/cardinality :db.cardinality/one
:db/unique :db.unique/identity
}
{
:db/ident :User/value
:db/valueType :db.type/string
:db/cardinality :db.cardinality/one
}
])
(d/transact conn user-schema)
(def user-name "User_name")
(def user-value "User_value")
(def user-data [
{
:db/id user-name
:User/name user-name
:User/value user-value
}
])
(d/transact conn user-data)
(def user-updated-value "User_value_updated")
(def user-updated-data [
{
:User/name user-name
:User/value user-updated-value
}
])
(def db (d/db conn))
(def asOfDbByBasisT (d/as-of db (d/basis-t db)))
(def txResult (d/with asOfDbByBasisT user-updated-data))
(def snapshotDbAfter (get txResult :db-after))
(def entity (d/entity snapshotDbAfter [:User/name user-name]))
(get entity :User/value)
```
**“User\_value”** is returned instead of expected **“User\_value\_updated”**

Maybe it is related Q, what should be basis-t of DB gotten by the function [as-of](https://docs.datomic.com/on-prem/clojure/index.html#datomic.api/as-of).
I see the basis-t of **as-of DB** is the same as DB used to get as-of db, is expected behavior?
```auto
(require '[datomic.api :as d])
(d/create-database "datomic:dev://localhost:4334/test-basis-t4?password=datomic")
(def conn (d/connect "datomic:dev://localhost:4334/test-basis-t4?password=datomic"))
(def user-schema [
{
:db/ident :User/name
:db/valueType :db.type/string
:db/cardinality :db.cardinality/one
:db/unique :db.unique/identity
}
{
:db/ident :User/value
:db/valueType :db.type/string
:db/cardinality :db.cardinality/one
}
])
(d/transact conn user-schema)
(def user-name "User_name")
(def user-value "User_value")
(def user-data [
{
:db/id user-name
:User/name user-name
:User/value user-value
}
])
(d/transact conn user-data)
(def db (d/db conn))
(def firstBasisT (d/basis-t db))
(def user-updated-value "User_value_updated")
(def user-updated-data [
{
:User/name user-name
:User/value user-updated-value
}
])
(d/transact conn user-updated-data)
(def db (d/db conn))
(def latestBasisT (d/basis-t db))
(def asOfDb (d/as-of db firstBasisT))
(def basisTFromAsOfDb (d/basis-t asOfDb))
(== latestBasisT basisTFromAsOfDb)
```
It is not clear to me why **basisTFromAsOfDb** is equal to **latestBasisT**
The doc says:
**basis-t** : Returns the t of the most recent transaction reachable via this db value.
But **asOfDb** can’t contain a transaction related to **latestBasisT** so why **basis-t** of **asOfDb** is **latestBasisT**
UPD. Maybe I got: if **basis-t** \> than **as-of-t** of some db then it means it is possible to switch to the newer version of this db. Maybe would be good to point this moment somehow in the docs 🙂
