> Teiid does not provide any information to the user that query actually failed. Only empty result is returned.
> Currently, issuing query like \[1\] produces source-specific query with syntax error \[2\] (result directly from Couchbase \[3\]). But Teiid returns empty result just like query succeeded with no rows.

> SELECT BQT1.SmallA.FloatNum FROM BQT1.SmallA WHERE BQT1.SmallA.FloatNum = 7
