How to Fix DBCC CHECKDB Errors in SQL Server

When you run a standard database consistency check and it returns errors in red, it can be terrifying. This usually means there's physical or logical corruption within your MDF/LDF files.

Step 1: Identify the Corruption

Look at the output. Does it say "allocation error" or "consistency error"? Allocation errors are easier to fix and often require a simple index rebuild.

Step 2: Emergency Repair

If it's severe, you normally have to enter SINGLE_USER mode and run REPAIR_ALLOW_DATA_LOSS. Doing this via command line is risky if you aren't an expert DBA.
