This could also happen if you need to migrate code written for another database platform with a different dialect of SQL to T-SQL. The sample row’s order date is 2022-01-11, so the first delimiter is 2022-01-09. Since this date doesn’t exist in the data, the actual first delimiter is the next existing date, 2022-01-10.

Partitioning is the concept of splitting large tables logically into smaller pieces for better performance of the database. However, a rule of thumb is that the size of the table should exceed the physical memory of the database server. The exact point at which a table will benefit from partitioning depends on the application.
