not set on the INSERT.
- OUT: Only sets the ID on the passed session and returns it. (`CreatedAt`, `AccessedAt`, are not set.)
New version:
```go
func (ds *Datastore) NewSession(ctx context.Context, userID uint, sessionKey string) (*fleet.Session, error) {
sqlStatement := `
INSERT INTO sessions (
user_id,
` + "`key`" + `
)
VALUES(?,?)
`
result, err := ds.writer.ExecContext(ctx, sqlStatement, userID, sessionKey)
if err != nil {
return nil, ctxerr.Wrap(ctx, err, "inserting session")
}
id, _ := result.LastInsertId() // cannot fail with the mysql driver
return ds.sessionByID(ctx, ds.writer, uint(id))
}
```
- IN: Define arguments that are truly used when creating a session.
- OUT: Load and return the fleet.Session struct with all values set (using the `ds.writer` to support read replicas correctly).
PS: The new `NewSession` version mimics what we already do with other entities, like policies (`Datastore.NewGlobalPolicy`).
