BUG FOUND: "DatabaseConnection_SetConnectionStringForSession" broken for MySQL server

When using the following action to switch between MySQL server database it fails.

DatabaseConnection_SetConnectionStringForSession (PlatformRuntime_API)

No database is switched, when using MySQL Server, it seems like this feature has not been implemented.

I am still waiting for a bug fix, there is no workaround solution for this bug!

Hi Robert,

Can't you directly ask support? Or don't you have a support contract?

Outsystems is aware of the issue, just waiting for a status update :)

Hey Robert,

In the future, please open a ticket with support. Specifically about this issue, we are aware of it and as I told you before, the issue was added to our backlog and we will address it accordingly to its priority. However, this is not a high priority issue so I can't tell you exactly when it is going to be fixed.

From what I undertood from your responses here you were able to switch the database in runtime and your issue was regarding the entities import, right?

Thank you,
Regards

No, DatabaseConnection_SetConnectionStringForSession does not work for MySQL.

When the issue was reported to Outsystems technical support, they were unable to reproduce the issue, and indicated  DatabaseConnection_SetConnectionStringForSession is functional - You have also tested it and reported the same.

Are you switching database running on two different servers? (same database name, same database table, two different servers)


I would like to switch two databases running on the server (two databases with different names, running on the same server)

Here is my connection string Server=10.1.x.x;Database=tempdatabase;Uid=root;Pwd=myp@ssw0rd;

Note: The original name of the database as configured in "ServerCenter" is "Platform" where as the database im switching to is "tempdatabase"

I found the issue! and it works!

Now we know that DatabaseConnection_SetConnectionStringForSession method will not switch a database schema if the extension entity contains a databaseschema, it should switch in either case but it does not!

I found that every imported databases contained a database schema in the table/view name, therefore this means we can not use the DatabaseConnection_SetConnectionStringForSession method without manually modifying the every entity imported table or view (ALOT of work, not practical)

Hey Robert,

That was the conclusion from this topic :) I know that reimport tables is something that is frequent for you and we will address that issue. However, as I mentioned in the previous post, we will address it accordingly to its priority and I can't tell you exactly when it is going to be fixed.


Thank you for your feedback,
Regards

Lara ah thanks for the reminder, so basically I tested the same thing twice and twice ended up with the same conclusion. we only work with external databases therefore we use the import feature alot!. Would you have a rough idea when it would be fixed within weeks? months? years? if it's many years away would it be possible for me to obtain the source code rather than be forever stuck? I could fix this issue myself! (without much or any help) if it's not important I wouldn't bother with it, but it is important.

Hey Robert,

Please follow up this issue with OutSystems Support.
