1. Create a connection and a db:  
(def conn (d/connect client {:db-name “users”}))  
(def db (d/db conn))

2. Add a user:  
(d/transact conn {:tx-data [{:user/name “Some name”}]}))

3. Query for user:  
(d/q '[:find ?ent  
:in $ ?name  
:where [?ent :user/name ?name]]  
db, “Some name”)))

User is not found, unless I redo `(def db (d/db conn))`

Is this the expected behavior?

Yep this is expected behavior. In order to issue a query against a Datomic database, you must retrieve the current database value. A database value is the state of the database **at a given point in time.** You can issue as many queries against that database value as you want, they will always return the same results. This is part of the value add of Datomic :).

You can always get the current DB in your query by doing the following:

```auto
(d/q '[:find ?ent
:in $ ?name
:where [?ent :user/name ?name]]
(d/db conn), “Some name”)))

```

In addition to what @jaret said, it’s often advantageous to use the `:db-after` provided by `d/transact` fn return map, when a flow of logic needs to transact data and run queries on the result of that data

Thank you, it became a little clearer 🙂
