When a resulting SQL statement has place holders of unknown type it causes trouble with hdb. As it enforces the data type that HANA provides. So in certain cases a place holder will default to nvarchar, but the actual value for the place holder will be a number. Which will be rejected as hdb only allows strings to be provided to these placeholders. There for this change converts all the values into a string before sending them to the prepared statement.
