![]() An offline index operation that creates, rebuilds, or drops a clustered, spatial, or XML index, or rebuilds or drops a nonclustered index, acquires a Schema modification (Sch-M) lock on the table. Table locks are applied for the duration of the index operation. ![]() ONLINE cannot be set to ON when an index is being created on a local temporary table. At the end of the operation, an S lock is very briefly held on the source if a nonclustered index is being created, or an SCH-M (Schema Modification) lock is acquired when a clustered index is created or dropped online, or when a clustered or nonclustered index is being rebuilt. At the start of the operation, a Shared (S) lock is very briefly held on the source object. This allows queries or updates to the underlying table and indexes to continue. During the main phase of the index operation, only an Intent Share (IS) lock is held on the source table. Long-term table locks are not held for the duration of the index operation. Online index operations are available only in SQL Server Enterprise, Developer, and Evaluation editions. The default is OFF.įor an XML index or spatial index, only ONLINE = OFF is supported, and if ONLINE is set to ON an error is raised.
