+# Using prepared statements, insertion of more than three columns with NULL
+# values fails to insert additional NULLS.  After the third column NULLS will
+# be inserted into the database as zeros.
+# First insert four columns of a value (i.e. 22) to verify binding is working

+# Then insert four more columns of integers, just for sanity.
