--TEST--
Test for retrieving encrypted data from char types columns using PDO::bindColumn
--DESCRIPTION--
Test conversion from char types column to output of PDO::PARAM types
With or without Always Encrypted, conversion works if:
1. From any char type column to PDO::PARAM_STR
2. From any char type column to PDO::PARAM_LOB
