             Summary: Wrong indexing with SUBSTRING function and OData4 translator
                 Key: TEIID-5278
                 URL: https://issues.jboss.org/browse/TEIID-5278
             Project: Teiid
          Issue Type: Bug
          Components: OData
    Affects Versions: 8.12.11.6_4
            Reporter: Jan Martiska
            Assignee: Steven Hawkins


SQL {{SUBSTRING}} function indexes strings from 1, but OData {{substring}} filtering function indexes from zero. This needs to be taken into account.
Currently a query containing {{WHERE SUBSTRING(stringkey, 1, 1) = 'x'}} will return items where the second character is x, but it should return rows where the first character is x.
