After I delete huge amount of data from a SQL Server database table, the database size increased.
When I run sp_spaceused it shows me 2625.25 MB. It used to be ~ 1800.00 MB before I deleted from table.
Is there any specific reason it keeps growing even if I delete data?
A temporary transaction log is often the reason for a notable increase of size after a huge delete.
It will eventually disappear on its own but you may remove the files if you need to reclaim the space.
