> This is an observation made in dynamic vdbs.
> When a view is defined without column name , data type, length as in the example below
> create view xyz as (
> select a, b, c from view_model.example
> );
> instead of inferring the column metadata from view_model, the string columns are created with length =4000, this is causing issues when querying such views from visualization tools like Tableau, these fields are forced to be converted to text and failing in the process.
> I would like to request an enhancement for dynamic vdbs to infer metadata from sources in such cases.
