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