+# 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        #
+#                                                                      #
