The statements are as follows: --BACKUP log TestDB with no_log UseTestDB; GO --Truncate The log by changing the database rec

although the result of our previous query was orderly, the new table generated after the run was not sorted by Subprenum and the order was chaotic.It was discovered that this was due to the limitations of SQL Server itself and that if there was a special need to require the data in the staging table to be ordered, the problem could be solved by "creating a clustered Index".

Key ConceptsConfiguration data compression can be implemented in both SSMS and T-SQL statements.Table and Index compressionFor row storage tables and indexes, using data compression can help reduce the size of the database. In addition to saving space, data compression can also help improve the performance of I/O-intensive workloads because the data is stored in fewer pages and queries require fewer pages to read from disk. However, when exchanging da
