That's not removing the userid and password, that's setting them to empty. But I'm not sure that this is the problem anyway.

I think Armeen will be able to help you better on this one.

Okay,

I've also been testing on 2021 beta (with Oracle DB) and just tried to reproduce the problem:

Indeed, I've changed my password to 'potato' (which is not a valid password) and I don't get any error message from the CONNECT; sqlca.sqlcode = 0 so that's bad.

In my opinion, this is a bug!

I have create a support ticket for you: https://www.appeon.com/standardsupport/track/view?id=6407

Hi Chen,

We further analyzed it on our side and found that it is not a bug.

In PowerServer 2021 Beta, if you configure the SQLCA corresponding Cache in the Database Configuration in the Web APIs tab in PowerServer Project, the connection info SQLCA used will come from the corresponding Cache connection info in Connection-Cache.json.

Any problems please let us know.

Regards,

David

The problem with this is that the examples and documentation say that you HAVE to fill the connection profile.

I'll try without....

(Same comment as on the ticket).

So if I want to access with different user and access rights, I cannot use caching? The only way to take advantage of caching is by all users running as the SAME user on the database?

That kinda seems like a big downside to me.

It would be nice if you could configure the caching without user and password, so you can pass those in the sqlca from code, but for now you cannot save the caching profile if you can't connect first by specifying user and password.

One workaround:

Put a small block of code after your connection attempt. This should be a simple retrieve from a small table:

       SELECT count(*) INTO :ll_count FROM small_table;

Now check the sqlca.sqlCode value.

Something like "select @@version" would also work and is very inexpensive to verify that a connection is live.
