> Key: TEIID-4967
> URL: https://issues.jboss.org/browse/TEIID-4967
> Project: Teiid
> Issue Type: Bug
> Components: Misc. Connectors
> Affects Versions: 8.12.x-6.4
> Reporter: Juraj Duráni
> Assignee: Steven Hawkins
> Priority: Blocker
> Fix For: 10.0, 8.12.x-6.4, 9.3.1

> I have a source model with FOREIGN TABLE and view model with VIEW which extracts subset of columns defined in FOREIGN TABLE.
> If one value in document is missing (i.e. from Teiid's point of view it's NULL), Teiid returns incorrect data from VIEW.
> In some cases, it returns NULL values for multiple columns (even if there is only one column with NULL).
> In other cases it shifts values - value from column c contains value of column c+1, column c+1 contains value of c+2 etc.
> For Source model, I tried both NATIVE and DDL metadata.
> If you need, I can provide you access to testing environment.
