> clause
> {code:title=PhoenixCalciteEmbeddedDriver.java} public Connection
> connect(String url, Properties info) throws SQLException {
> if (!acceptsURL(url)) {
> return null;
> }
>
> Properties info2 = new Properties(info);
> setPropertyIfNotSpecified(
> info2,

> PhoenixRelDataTypeSystem.class.getName());
> setPropertyIfNotSpecified(
> info2,
> CalciteConnectionProperty.CONFORMANCE.camelName(),
> SqlConformance.ORACLE_10.toString());{code}
> Note that the actual failure occurs when the SqlValidator rejects the
> statement
