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