“Switch” Huge Non Partitioned Tables in Seconds
Read OriginalThis technical article details a method for performing schema changes on extremely large SQL Server tables (e.g., 5.8B rows) using the ALTER TABLE...SWITCH TO command. It explains how this operation, often associated with partitioned tables, can be applied to non-partitioned tables to instantly move data to a new staging table with a modified schema (like identity increment), avoiding slow INSERT operations and heavy transaction log usage.
