Hi,
The database mechanism "holds" the deleted or crossed records, for several reasons (undo the deletion).
In order to delete the "deleted" records permanetly, open the HFSQL Control Center, go to the desired table, press right click and choose Optimize and repair. Then the Optimizing window opens, check "Rebuild the indexes" option, as well as "Delete the inactive records". Press "Start Optimizing".
Hope to help.
Regards
