+--TEST--
+Test fetch from binary columns, without setting binary encoding.
+
+--DESCRIPTION--
+Verifies GitHub issue 270 is fixed, users could not retrieve the data as inserted in binary columns without setting the binary encoding either on stmt or using bindCoulmn encoding.
+This test versifies that the data inserted in binary columns can be retrieved using fetch, fetchColumn, fetchObject, and fetchALL functions.
