How many clustered indexes can you create for a table in dwh? In case of truncate and delete command what happens to table, which has unique id.
Answer / Farha Adil
In a data warehouse, you can create multiple non-clustered indexes on a single table but only one clustered index. The primary key constraint is used to create the clustered index by default if not specified otherwise. When a table with a unique ID (such as a primary key) is truncated or deleted, all data is removed and the structure remains intact.
