If the database is in emergency mode, you have to run CheckDB with the repair_allow_data_loss option to have a chance of bringing it back online. CheckTable is not sufficient. That or restore from backup.

Do you know how much data you're going to lose in this case?

Can you run the following, before trying a repair, and post the full and complete output?

DBCC CHECKDB (<Database Name>) WITH NO_INFOMSGS, ALL_ERRORMSGS
