I would never use a table variable for this -- if something goes wrong after the DELETEs, but before the output has been processed, the data is gone, with no way to get it back.

Do you have a separate db that you use for export / other utility purposes? If not, you may want to create one. Output the rows to be deleted to a table, then delete the rows.

Process that other table within a transaction, so that the rows must be successfully exported before the export table has its rows deleted.
