explain different types of index ?

Asked: Apr 14, 2023

SQL indexes are nothing more than a technique of minimizing the query's cost. The higher the query's cost, the worse the query's performance. The following are the different types of Indexes supported in SQL:

  • Unique Index

  • Clustered Index

  • Non-Clustered Index

  • Bit-Map Index

  • Normal Index

  • Composite Index

  • B-Tree Index

  • Function-Based Index
