Dears,
I face the following error message when I try to attach my existing XX.MDF and XX_Log.LDF files:
---------------------------
Microsoft SQL-DMO (ODBC SQLState: HY000)
---------------------------
Error 602: Could not find row in sysindexes for database ID 7, object ID 1, index ID 1. Run DBCC CHECKTABLE on sysindexes.
What's the possible reason and solution
Thanks,

Hi, you got the same error as me. But were those database files you trying to attach created by your local host or from outside your local host
I only fixed this error with files created from my local host while database files from outside of my loca host still unsolved yet.
