> Unexpected sequential dependency between virtual table column order and mapping column sequence.
> The TEIID statement to create a virtual table goes like:
> CREATE VIEW TargetModelViewName (
> ColumnA …							1
> ColumnB …							2
> ColumnC …) …							3
> AS SELECT 
> SourceModel.SourceTable.ColX AS ColumnA,			1
> SourceModel.SourceTable.ColY AS ColumnB,			2
> SourceModel.SourceTable.ColZ AS ColumnC;			3
> In any 4th+ generation query language a positional dependency is not expected, and therefore the following statement should also work, but fails in the TEIID 
> CREATE VIEW TargetModelViewName (
> ColumnA …							1
> ColumnB …							2
> ColumnC …) …							3
> AS SELECT 
> SourceModel.SourceTable.ColX AS ColumnA,			1
> SourceModel.SourceTable.ColZ AS ColumnC,			3
> SourceModel.SourceTable.ColY AS ColumnB;			2
