             Summary: Infer field metadata from the source columns
                 Key: TEIID-5356
                 URL: https://issues.jboss.org/browse/TEIID-5356
             Project: Teiid
          Issue Type: Enhancement
            Reporter: Chandra Akkinepalli
            Assignee: Steven Hawkins


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.
