I should add, I'm not having much success in terms of reporting. We don't have (or I can't get) the Management Portal, and I can't seem to use SSMS to write queries against the data, and in Power BI, the IRIS connector isn't allowed for dataflows.

I am missing something super obvious, I know I am!

What tools do other people use to write reports against IRIS?

Thanks.

Many thanks for your reply.

That all sounds a bit beyond me! I know I've tried making a temp table in SSRS on the IRIS database but it didn't like it at all (giving vague errors), so gave up on that idea.
I don't know what a classmethod is or how to create it.

It seems very strange to me that you simply can't simply reference a specific parameter whilst ignoring others. I don't doubt it, however!!

Regards,

Many thanks, this will give me some weapons in my arsenal! ANd thanks for the quick reply also.

But what about if I'm trying to cascade parameters? Parameter one influences dataset one. Then I have a parameter two which is populated by the results of dataset 1. This parameter is used in dataset two, but the field relating to parameter one doesn't exist in dataset two.

Does that make sense? Basically, in your example, pretend column one doesn't exist as it relates to a different dataset. So I have multiple parameters, some of which are only able to be used on certain datasets.

Thanks.
