--TEST--
|
|
Test fetch from binary, varbinary, varbinary(max), image 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 verifies that the data inserted in binary columns can be retrieved using fetch, fetchColumn, fetchObject, and fetchAll functions.
