--TEST--
Verify the Binary and Char encoding output 
--DESCRIPTION--
Verify the Binary and Char encoding output when binding output string with SQLSRV SQL TYPE option with different size
Will not convert this test for AE testing because the goal of this test is to deliberately use a different size for SQLSRV SQL TYPE from the designated output param in the stored procedure
