2 Answers. It isn't possible to create multiple clustered indexes for a single table. These are the columns included in the index definition. There can be only one clustered index per table, because the data rows themselves can be stored in only one order.

Also, what is a clustered index? A clustered index is a special type of index that reorders the way records in the table are physically stored. Therefore table can have only one clustered index. The leaf nodes of a clustered index contain the data pages.

Similarly, you may ask, how many non clustered indexes can you have?

SQL Server allows maximum up to 249 NON-CLUSTERED indexes that can be created in single table.

Which one is faster clustered or nonclustered indexes?

Nonclustered index contains only data from indexed column(s), and a row_id pointer to where the rest of data is. Therefore this particular nonclustered index is lighter and less reading is required to scan/seek through it and this particular query will work faster. T1's clustered index is around 1.6 GB in size.
