Corruption of Spatial Indexes
When working with a table that has a spatial index, you may notice that a SELECT query that previously worked begins returning incorrect results, or you may encounter the following errors when attempting an UPDATE or DELETE operation:
Unable to find index entry in index ID %d, of table %d, in database '%.*ls'. The indicated index is corrupt or there is a problem with the current update plan. Run DBCC CHECKDB or DBCC CHECKTABLE. If the problem persists, contact product support.
Microsoft is currently investigating the cause of this problem.
To work around this issue, drop the spatial index and then recreate it.
