Clustered indexes physically order the data in the table, while non-clustered indexes do not.
Clustered indexes determine the physical order of data in the table, while non-clustered indexes do not.
A table can have only one clustered index, but multiple non-clustered indexes.
Clustered indexes are faster for retrieval of data, especially range queries, compared to non-clustered indexes.
Non-clustered indexes are stored se...
