# #
# This test aims at using string/char literal in comparison operators #
# without explicit type-cast. This is a bug test for Bug#11766521 #
# - Incorrect result is returned if string/char literal is used with #
# comparision operator and bit data type column. Test is extended to #
# include numeric data type comparison with string/char literal #
# #
# #
# Creation: #
# 2011-05-10 vfisrekar Implement this test as part of Bug#11766521 #
