BUG #: 57899 (SQLBUG_70)
Table corruption errors may occur on index pages under the following conditions:
  1. The SELECT INTO/BULK COPY option is on.
  2. A bulk copy program (BCP) operation is done with the IGNORE_DUP_KEY option specified.
  3. The target table has a nonclustered index.
The underlying data pages are in a consistent state; however, the following errors can be seen when you run DBCC Checkdb:
Server: Msg 8951, Level 16, State 1, Line 1
Table Corrupt: Table 'table_name' (ID 1941581955). Missing or invalid key in index 'index_name' (ID 2) for the row:
Server: Msg 8955, Level 16, State 1, Line 1
Data row (1:365:0) identified by (RID = (1:365:0) ) has index values (store_number = 1211 and ssn = '440921916' and date_worked = Feb 7 2000 12:00AM?|??WeG and clock_in_time = '16:53' and clock_out_time = '19:08').
NOTE: The issue does not occur if there is a clustered index on the table in question.
To work around this problem, rebuild the affected index by using one of the following methods:
  • Drop and then re-create the index.
  • Use the DBCC DBREINDEX statement.
  • Use the REPAIR_FAST option with DBCC CHECKTABLE. (In some cases, it may be necessary to run this command more than once.)
