CREATE PROCEDURE spDeleteRows
/*
Recursive row delete procedure
It deletes all rows in the table specified that conform to the criteria selected,
while also deleting any child/grandchild records and so on. This is designed to
do the same sort of thing as Access's cascade delete function. It first reads
the sysforeignkeys table to find any child tables, then deletes the soon-to-be
orphan records from them using recursive calls to this procedure. Once all the
child records are gone, the rows are deleted from the selected table. It is
designed at this time to be run at the command line, but could also be used
in code, but the printed output will not be available.
