A full table scan (also known as a sequential scan) is a scan made on a database where each row of the table is read in a sequential (serial) order and the columns encountered are checked for the validity of a condition. Full table scans are usually the slowest method of scanning a table due to the heavy amount of I/O reads required from the disk which…
The analysis highlights Examples, When the optimizer considers a full table scan and Pros and cons as prominent areas in the source structure around Full table scan.
