> Repo:
> 1. Let's create a branch
> ALTER TABLE Devices CREATE Branch *Sandbox*
> 2. Check the existence for evidence
> SELECT * FROM `default`.`devices`.`refs`;
> The References show it properly

> 3. Select from branch
> SELECT * FROM default.Devices.branch_Sandbox;
> But if the select it would throw an exception:
> {color:#de350b}Error while compiling statement: FAILED: SemanticException
> Cannot use snapshotRef (does not exist): sandbox{color}
> I guess the select operator does have a simple equals and does not check the
> cases also the cultureInvariant could be a different issue
> *Exception*
