--TEST--
|
|
Test parametrized insert and sql_variant as an output parameter.
|
|
--DESCRIPTION--
|
|
Normally, sql_variant is not supported for output parameters, this test checks the error handling in this case. However, when Always Encrypted is enabled, we are able to bind output parameters with prepared
|
|
statements.
