What is scan table/view and seek table/view when its occurs? : sql server database administration..

Answer / Antul Awashthi

"Scan Table/View": A full scan or table scan is a data retrieval operation in SQL Server where every row of the table or indexed view is read to satisfy a query. It's used when an index isn't available, or the query requires access to unindexed columns.

"Seek Table/View": A seek operation in SQL Server is a data retrieval method that uses an index to find specific rows quickly without reading all the rows of the table or view. The database engine only reads the pages where the matching key values are found."
