Parse the ? when creating credentials with SAS token
When attempting to backup to URL a credential needs to be created. One method to do this is to use a Shared Access Signature token from Azure, which when generated includes a leading "?" question mark.
However, when that SAS token is transposed into a CREATE CREDENTIAL T-SQL code that leading ? must be removed. This is very confusing and leads to wasted time. The documentation does clearly state that it has to be removed first, however it would be a better end user experience to just have the CREATE CREDENTIAL command recognize the leading ? and remove it.
