What is SQL CREATE INDEX: Syntax & Examples about?

The SQL CREATE INDEX statement is used to create indexes on tables to speed up data retrieval, with the option to create unique indexes that do not allow duplicate values. The syntax varies across different databases, and indexes can be removed using the DROP INDEX command without affecting the underlying data. It is recommended to create indexes only on frequently searched columns due to the additional time required for updates.
