Hey All,
Returning to PB community after 4 years absence. Sorry, y'all!

Anybody has any experience connect PB app to Google's Big Query using any kind of DB driver?
These days I sadly do more data then PowerScript. Maybe I can cross back, especially if my PB apps can access Big Query.

THX all for your contributions. My summary:
1) JDBC is the better option over ODBC but comes with a support challenge.
2) Alternative, use a C# .NET component to do the Big Query access, use it as an adapter/façade style pattern.

Once I get it working I may post an article since others may also want to query BQ from PB.

you could also use the PB HTTP client to run the query and get the results, and then push the results into a datawindow/store.

I this for 'external' database queries via ADO.DB though the ole object where i can't use a transaction object in PB (powerserver for example).

Hi, Michael, welcome back! It's good to hear from you. Unfortunately, all of my data is relatively tiny, so I don't have any experience that will help you out. Please let us know if you find something that works for you?

Best regards, John

Hi Michael, welcome back!

No experience with it, but I'd recommend to go for the JDBC driver, not the ODBC. Appeon now no longer officially supports JDBC, but if you jump through some hoops, it still works. https://www.appeon.com/developers/get-help/knowledgebase/4434

It'll work better than ODBC. Also, don't embedd any stored procedures / function. Use RPC and it should work fine.

I guess there's no need but here's a link: https://cloud.google.com/bigquery/docs/reference/odbc-jdbc-drivers

regards.

Hi Chris,

A), B) true.

C), our apps run in-house C/S so the security issues are not so big, plus we've eliminated the recent LOG vulnerability.

D) haven't seen any, runs fine on all systems.

E) No deployment issues at all. We have a subfolder with a self-cointained JRE and don't even have to install a client.



I DO wish that Appeon would have an ODBC that works properly with our Tibero databases, but they don't. Loosing the possibility to work with Tibero would be fatal for our company.

regards.

That's great Miguel but many sites that I know, their production teams do not allow that old JRE to be deployed into production. Especially, after performing a TRA (Threat & Risk Assessment) where that JDK fails.

Hi Michael;

Yes, since PB no longer supports directly calling a Java Class - then a .Net Assembly that be directly called via the DotNetObject in PB would be a good alternate choice IMHO.
