SQL Server uniqueidentifier handling
------------------------------------

                 Key: TEIID-880
                 URL: https://jira.jboss.org/jira/browse/TEIID-880
             Project: Teiid
          Issue Type: Quality Risk
          Components: JDBC Connector
    Affects Versions: 6.0.0
            Reporter: Steven Hawkins
            Assignee: Steven Hawkins
            Priority: Optional
             Fix For: 6.3

SQL Server's uniqueidentifier is typically imported as a string, but cannot be used in comparable operations (distinct, order by, group by).  Our designer cost analyzer logic already compensated for this, but a more general fix would be to wrap the uniqueidentifier as cast(col as char(36)), which would be safe.
