| Event Information | According To Microsoft:
Cause:
This error occurs when you try to create an index using the DROP_EXISTING clause of the CREATE INDEX statement on a column or columns containing data that is not in sorted order. When this error occurs, no index is created.
The DROP_EXISTING clause speeds the creation of an index when the data in the table is already in order. The space required to build a clustered index is less when the DROP_EXISTING clause is used.
The DROP_EXISTING clause speeds index creation only for clustered indexes or unique nonclustered indexes. Creating a nonunique, nonclustered index with the DROP_EXISTING clause may succeed, but there is no improvement in performance.
Resolution:
Use either of these strategies:
Execute CREATE INDEX with the DROP_EXISTING clause.
Drop and re-create the index without any clauses.
You can also use the SORTED_DATA_REORG clause, which physically reorganizes the data. |
