+# It would be totally crazy to have to recreate the whole table just to change one column type,
+# just because MS SQL treats each DEFAULT as a constraint object that must be dropped
+# before anything can be done to the column.  Since all defaults here are unnamed, there is
+# no easy way to drop them!  The hairy piece of code below removes all DEFAULT constraints
+# from InventoryItems.
+
+# SO: anything that's NULLable is by default NULL, so please don't declare DEFAULT(NULL), 
+# they do nothing but prevent changes to the columns. If you really
+# need to have DEFAULTs or other constraints, give them names so they can be dropped when needed!
