Anilkumar Gingade commented on GEODE-7802:
------------------------------------------

I don't understand this requirement. 
Even in case of other RDBMS query language, the existence of columns are 
determined either during query-compilation or query-execution time; and also 
for complex queries it can only determine the existence during execution time; 
that is what GEODE OQL engine is doing.

One thing that could help to call out is; OQL query engine determines the field 
or methods on the object during query execution time.

> Community member @deepak khopade requests that we add a disclaimer to the 
> user guide stating that OQL queries are not pre-screened for references to 
> nonexistent attributes. The assertion is that users who have experience with 
> other query models may expect Geode to apply such validation. In the Geode 
> model, attributes and methods are resolved at runtime during query execution 
> - the server does not know what's actually stored in a region until the query 
> is executed.
> The disclaimer could be added in one of two places:
> Query Language Restrictions and Unsupported Features 
> ([https://geode.apache.org/docs/guide/111/developing/querying_basics/restrictions_and_unsupported_features.html])
> or
> Querying FAQ and Examples 
> ([https://geode.apache.org/docs/guide/111/getting_started/querying_quick_reference.html])
