# sub create_SQLpreparedinsert
#
# in  : a database handle, the name of the table to update, and an arr
+ay
#       of fieldnames.
# out : a statement handle.
#
# this sub will create a prepared statement, or die with a verbose err
+or.
# note that under sybase, prepare statements may not include TEXT or I
+MAGE types.
# for those cases, use create_SQLinsert.
# Typically, however, prepared statements will run faster, so this sho
+uld be the sub of choice.
