When you create the log shipping you have 2 choices. You can configure restore log operation to be done with norecovery or with standby option. If you use the norecovery option, you can not issue select statements on it. If instead of norecovery you use the standby option, you can run select queries on the database. Notice that in that case you also have to make the decision what to do when it is time to restore the log, but there are users that are using the database. You’ll have to wait with the restore or to kill the users’ processes before issuing the restore log statement. All of those options can be configured with the wizard.

as Adi pointed out you cannot query the database in the norecovery state. Bear in mind with the standy option when log file restores occur users will be kicked out without warning by the restore process. If you're needing to query the database that much then Log shipping probably isn't your best option.

If you're asking how can you bring the database back online when in the norecovery state then simply issue

RESTORE DATABASE MYDATA WITH RECOVERY

Bear in mind that the log shipping config will be broken

Acutely when you configure the log shipping with standby option, you can also select between 2 choices – kill all processes in the secondary database and perform log restore or don’t perform log restore if the database is being used. Of course if you select the second option, the restore operation might never run if someone opens a connection to the database and doesn’t close it, so it is better to use the first option.
