Delete matching database rows

apparently the only method to update on the target table in easymorph is the one I proposed to you in the previous message:
-Import the lines to update in EasyMorph
-Save them in a temporary .dset file
-Update rows in EasyMorph
-Delete rows from the database table
-Export the updated rows in the database table
-Delete the temporary .dset file
