Anybody got a similar issue? 2020-01-21T18:03:33Z Dynamic Source File Configuration with SFTP 2020-01-21T07:38:04Z 2020-01-21T07:38:04Z Hi I am experimenting with a prototype for my organization thru Denodo Express Virtual Data Port. Here is my problem: 1) Daily files are deposited into sftp via batch upload. 2) I have configured the data source in denodo to point to the sftp but it requires me to specify the .txt location, so its only picking up a single file. 3) How do i iterate through all the files in the sftp directory such that the virtualized data model is dynamically refreshed to pick up values from the last updated files? I am available for a chat to solve this and if required to share my screen as well. Pls let me know Rgds, Michelle 2020-01-21T07:38:04Z Type of model in the join 2020-01-20T17:35:45Z 2020-01-20T17:35:45Z The Denodo tool has the join function that allows you to join or integrate data from different sources, however, this works by means of PK (primary key) or FK (foreign keys), I would like to know what models are formed. In other words, it is a star model or a relationship entity model or another. I want to know specifically what model is created when we join the tables using the PK and FK. 2020-01-20T17:35:45Z Join with Excel data source 2020-01-20T13:38:14Z 2020-01-20T13:38:14Z Hi, Is there a way to optimize a join from Excel that has 1.7M registers with other one that has 25M registers. The problem here is it takes longer than 15 minutes so it times out. Any suggestions? Thank you, Best regards. 2020-01-20T13:38:14Z 2 solution managers 1 for production and1 for others 2020-01-19T08:36:01Z 2020-01-19T08:36:01Z Hi, Can we have 2 solution managers installed. One for production and 2nd for other dev/test/QA etc. The reason is production team will not take any responsibility of any enviornment other than production. What's the best practice to deploy scripts to production server, since Solution managers are on different machines. Has anyone dealt with similar situation?

In other words, if I have loaded some tables in the Denodo, the transactional systems continue to fill my database (tables), as Denodo can be configured so that they reload the tables with the new data automatically and replicate at Views created 2020-01-18T04:20:12Z PHP ODBC Binding issue with numbers/integers 2020-01-17T15:14:25Z 2020-01-17T15:14:25Z Closely related to this question: https://community.denodo.com/answers/question/details?questionId=9060g000000TQpWAAW&title=ODBC+binding+parameters Binding any type of date, datetime, varchar or char seems to work. however when doing integer or decimal numbers, I receive the below error in PHP PDO. We are running PHP7.3, Denodo version 7 with a PostgreSQL backend. We've also tracked the server with logging enabled however the statement didn't even seem to hit the server. ``` DebugPDOStatement Object ( [queryString] => SELECT * from rds_homt_public_shipped_orders where ordernumber = :ordernumber ) SQL: [77] SELECT * from rds_homt_public_shipped_orders where ordernumber = :ordernumber Params: 1 Key: Name: [12] :ordernumber paramno=0 name=[12] ":ordernumber" is_param=1 param_type=1 Array ( [0] => [1] => 7 [2] => ERROR: Error executing query.

What I also find strange is that the ERROR message is cut off after X many characters. Is there anything you can do to help us?
