40  * Code to delete rows from a table.
41  *
42  * We delete rows by blanking them out rather than trying to remove the row.
43  * This appears to be what the native MSI does (or tries to do). For the query:
44  *
45  * delete from Property
46  *
47  * some non-zero entries are left in the table by native MSI. I'm not sure if
48  * that's a bug in the way I'm running the query, or a just a bug.
