The name of the view that fails to complete contains the phrase: perf_updown_capture_chart_5yr. The error happened on 9/29 at ~9:29AM.

Which Steps I did :
I connected JSON file and create BaseView on that. Then Flatten the BaseView.
Then Create Role and Add Privileges on Role Level. Next create User and Assign the Role to the user.2022-09-29T08:36:43Zcreate_datetime >= '@LAST_REFRESH_DATE' in incremental cache not delegated to the source2022-09-27T15:45:01Z2022-09-27T15:45:01ZI created a baseview over a cTree Datasource.
I then enabled full cache, which works fine.
Finally, I would like to enable incremental caching.
I set the condition to create_datetime >= '@LAST_REFRESH_DATE'
When I run a query, the execution trace shows, that the data is gathered from the cache, as well as from the original source. However,
the condition create_datetime >= '@LAST_REFRESH_DATE' is not pushed down to the source, but the complete data is loaded, and the filtered within the vdp.
If I add another where statement to the query, like "create_datetime >= now()", this one is correctly pushed to the source.
So what could be the reason, that the condition for incremental caching is not pushed down?2022-09-27T15:45:01ZREST Webservice as DataSource with optional parameters2022-09-27T14:59:00Z2022-09-27T14:59:00ZI am using a REST Webservice as a Datasource.
To get the data, the Webservice GET function takes three Parameters "accountingClientId", "customerId" and "invoiceId".
The first two are mandatory, the third is optional.
I managed to do this by using ^ExecuteIfIsNotNull function in the URI of the GET,
https://service.company.com/Finance/OpenedPost?accountingClientId=@{accountingClientId}&customerId=@{customerId}^ExecuteIfIsNotNull("&invoiceId=",@invoiceId,"","")
and setting "invoiceId" to OPT in the view search method by VQL:

My Problem is now, that, although I get a complete result from the view, the returned INVOICEID is always NULL.
It works for the other two parameters.2022-09-27T14:59:00Zspecifying the adapter for a jdbc datasource from VQL (as opposed to: from the admin tool)2022-09-27T10:26:32Z2022-09-27T10:26:32ZWhen creating a jdbc datasource via VQL with a driver from lib/extensions/jdbc-drivers-external/... it seems that always the generic adapter is selected.
However I want to control the adapter. Is that possible via VQL or in any other way programmatically?
Thank you2022-09-27T10:26:32ZLIKE is not working as expected2022-09-26T16:03:16Z2022-09-26T16:03:16ZI am running this code on a Denodo database,
```
SELECT TRUNC(tran_dttm) as dt,
substr(device, 1, 3) AS tech,
SUM(out_qty) AS moves
FROM database.table
WHERE facility IN '****'
and device regexp_like '^P.*'
AND tran_dttm >= DATE '2020-09-26'
AND tran_dttm <= DATE '2022-09-26'
AND tran IN 'W03' or tran IN 'W04'
GROUP BY TRUNC(tran_dttm),
substr(device, 1, 3)
```
I expect a result that includes only "tech" entrys that start with a "P", but I get results like the following.

Why am I getting results that do not match the regexp pattern?

Is there any alternative other than to use POST menthod and override it with "X-HTTP-Method-Override: GET"? I'm using Denodo 8.0.
