FIX: An Access Violation May Occur When You Run DBCC DBREINDEX on a Table That Has Hypothetical Indexes (818097)

SYMPTOMS

If you run DBCC DBREINDEX on a table that contains one or more hypothetical indexes, an access violation may occur in the CTableMetadata::LoadIndex function. Hypothetical indexes are created by the Index Tuning Wizard during the tuning process. The indexes are typically dropped at the end of the Index Tuning Wizard process. However, in some cases, such as an Index Tuning Wizard process that is not successful, these indexes may not be correctly removed.

Additionally, when you run DBCC CHECKDB, you may receive the following error message that indicates that the sysindexes system table is corrupted:

Server: Msg 7995, Level 16, State 3, Line 1
Database 'test' consistency errors in sysobjects, sysindexes, syscolumns, or systypes prevent further CHECK processing.

When you run DBCC CHECKTABLE on sysindexes, the following errors may be reported:

Server: Msg 2537, Level 16, State 40, Line 1
Table error: Object ID 2, index ID 0, page (1:3282), row 5. Record check (length <= colInfo.CbMaxLen () && pCol != NULL) failed. Values are 1120 and 1088.

Server: Msg 2537, Level 16, State 1, Line 1 Table error: Object ID 2, index ID 0, page (1:3282), row 6. Record check (length <= colInfo.CbMaxLen () && pCol != NULL) failed. Values are 1120 and 1088.

Server: Msg 8964, Level 16, State 1, Line 1 Table error: Object ID 2. The text, ntext, or image node at page (1:24219), slot 2, text ID 108377276416 is not referenced.

Server: Msg 8964, Level 16, State 1, Line 1 Table error: Object ID 2. The text, ntext, or image node at page (1:24219), slot 4, text ID 108377341952 is not referenced. DBCC results for 'sysindexes'.

The Index Tuning Wizard creates hypothetical indexes as part of the tuning process. These indexes are typically deleted if the wizard finishes, but the indexes may remain if the process is terminated. The following Microsoft Knowledge Base article contains a script that can be used to remove these indexes:

293177 BUG: Hypothetical Clustered Index From Index Tuning Wizard May Cause Recompile Loop

After you run this script, the access violation will be resolved and the errors in sysindexes will be corrected.
