Denodo community Q&A RSS feed Latest Denodo community questions Hiding columns that users cannot execute 2024-04-19T16:24:35Z 2024-04-19T16:24:35Z I have implemented column level security on a view. As expected when the restricted uers executes select * from the view they get an error message that says that they do not have privileges on certain columns. However, the user can see the columns that they do not have access to. Is there a way to prevent the user from seeing the columns that they do not have access to? 2024-04-19T16:24:35Z Returning a Select Statement in a VQL Stored Procedure 2024-04-19T16:01:32Z 2024-04-19T16:01:32Z Hi everyone. Simple question here. I want to create a VQL Stored Procedure that returns a Select Statement, how do I do it? I have searched through the Denodo documentation for this but haven't found any reference about it. Thanks in advance 2024-04-19T16:01:32Z Vdp-queries log generation 2024-04-19T09:18:03Z 2024-04-19T09:18:03Z Hello Team, We are aware that Denodo logs are produced in two directories: DENODO_HOME/logs/vdp and DENODO_HOME/tools/monitor/denodo-monitor/logs (when Denodo Monitor is running). The file "vdp-queries.log" exists in both locations mentioned above. However, vdp-requests.log is only generated in the Denodo Monitor directory and not in DENODO_HOME/logs/vdp. Please advise on in which case entries are generated in DENODO_HOME/logs/vdp/vdp-queries.log as well. Additionally, could you confirm if there is a log4j2.xml file for logs in DENODO_HOME/tools/monitor/denodo-monitor/logs? 2024-04-19T09:18:03Z VQL STORED PROCEDURE/INTERFACE VIEW 2024-04-19T08:53:31Z 2024-04-19T08:53:31Z Hi everyone, this is the SP that creates the view interface and it's intended to be created in the indicated database specified in the parameter.

Reading the user manual about this custom wrapper, it seems to me that ony clusters "based" on Azure can connect to Denodo. It is correct? I'm using a cluster "based" on AWS and I can't connect with this custom wrapper.. there is a way to connect thi AWS based cluster on MongoDB Atlas from Denodo? Am I missing something?

We are aggregating data from old and new version of RAMOS (basically from two databases) into one source domain and building views on top of that for our downstream systems to consume. Can you suggest the right approach and what all do we need to do in order to achieve this business objective? 2024-04-15T08:19:13Z first of current year 2024-04-12T17:41:24Z 2024-04-12T17:41:24Z how do I pull first of current year and forward? for example, when the date is currently 1/1/24 to 12/31/24, I always want to get results from 1/1/2024 and forward. 2024-04-12T17:41:24Z
