Julian Hyde commented on CALCITE-2208:
--------------------------------------

The author of [https://github.com/apache/calcite/pull/1123] has closed the PR.

Also, as I commented, I don't think 
[https://github.com/apache/calcite/pull/647] is suitable.

Therefore I am removing the 'pull-request-available' label.

> MaterializedViewTable.MATERIALIZATION_CONNECTION used for validating views 
> uses ORACLE lex by default. Calcite expands the view sql to uppercase so when 
> schemas used in such view sql are used are declared in lowercase - Calcite 
> does not find needed objects to resolve and validate the view sql.
> It does really not work even when end user creates connection with 
> lex=oracle, but uses uppercase for the names of its tables. 
> It would be best when MaterializedViewTable.MATERIALIZATION_CONNECTION would 
> be replaced by connection of an end user or dynamically created connection 
> with passed lex from end user connection. 
> Quick and dirty solution is to create 
> MaterializedViewTable.MATERIALIZATION_CONNECTION with caseSensitive=false;
