-----------------------------------

             Summary: PrestoDB translator - error executing locate(string, string, int)
                 Key: TEIID-4680
                 URL: https://issues.jboss.org/browse/TEIID-4680
             Project: Teiid
          Issue Type: Bug
          Components: Query Engine
    Affects Versions: 8.12.8.6_3
            Reporter: Juraj Duráni
            Assignee: Steven Hawkins


Teiid translates function *locate(string, string, int)* directly to *strpos(string, string, integer)*, but there is no such function in PrestoDB (see [doc|https://prestodb.io/docs/current/functions/string.html]).
