Teiid is attempting to push a string concat down. ------------------------------------------------- Key: TEIID-1438 URL: https://issues.jboss.org/browse/TEIID-1438 Project: Teiid Issue Type: Bug Components: Query Engine Affects Versions: 7.1.1 Reporter: John Doyle Fix For: 7.1.1 That attached VDB is invoking the yahoo quote service. Invoking the BrokenQuote procedure like this: Exec VGetQuote.BrokenQuote('IBM'); results in the following exception: Remote org.teiid.api.exception.query.QueryPlannerException: Source command "EXEC GetQuote.invokeHttp('GET', null, concat('?f=snd1l1&s=', VGETQUOTE.BROKENQUOTE.Ticker))" contains non-pushdown constructs. The GetQuote and Quote procedures divide the SQL from BrokenQuote into two procedures and does not produce the exception, but I don't see why BrokenQuote does not work.
