Hi all. I’m a confused about how to use a flex repeater to show dynamic data. Let’s say I have 10 rows in a database, and I always have those same 10 rows. Much of the data is static. I can use parameters to pass those into a view in the flex repeater. But there is also data that is dynamic. For example, there’s a quantity field, and the quantity changes fairly frequently, e.g. at least one row updates every second or so. A template repeater in Vision had an update rate, but Perspective only seems to update when refreshed. I can’t figure out how to continuously update the view in the repeater. The only thing I could think of was to create a query tag and use the index in the repeater to point to a location in the dataset of the query tag. But I ran into problems there, too, because I have different screens that would need point to different tags, so I ran into things like toBoolean(lookup({[default]MyQueryTag1},{view.param.Row}, 0, ”MyColumn”, ”IsFull”)), but I need to replace “MyQueryTag1” with a “MyQueryTag{X}”, where I’m not even sure how I’m going to get “X” in there, and I definitely don’t see how to make that tag indirect inside this expression. (If I don’t need an expression, I can use indirect tags, but I’m still not sure where to get “X” from. It’s known on the View that has the repeater, and I suppose I could pass it as a parameter to every instance.) Long story short, how do I have dynamic data for the instances in a flex repeater where the data is coming from a database table? Any help is greatly appreciated. ---

Is there any chance you can edit your post to introduce paragraph breaks to break up the wall of text and format code blocks as shown in [Wiki - how to post code on this forum](https://forum.inductiveautomation.com/t/wiki-how-to-post-code-on-this-forum/77831)? ---

You use an SQL query binding on the root data type of the ‘instances’ and use a script transform to make the returned data form the correct structure in json to produce the right number and composition of instances. ---

Query bindings have a `Polling` parameter, which should do pretty much what he asks for. ---

Sorry about that. ---

Someone pointed out that query bindings have a “Polling” option, which I completely missed, and is equivalent to the update rate in a Vision template repeater. So problem solved. But somehow I can no longer see that reply so I can’t accept it as the solution. I feel dumb that I didn’t see it; it’s grayed out until you check it, and it’s near the bottom of the section, so I just overlooked it. ---

I'm the one who posted that, and I can't find that reply either. Something weird happened... ---

`on delete cascade` 😛 I figured it would be something like that, but that sounds like a bug to me. ---

Note that only query bindings have that parameter (I think ?). If you need a polling rate on a script binding, you can call that script in a `runScript` expression, which also takes a poll rate (which can be set to 0 to run the script just once, and when its parameters change) You could also have a ‘timer’ custom property with an expression binding that runs `now(x)` with `x` being your poll rate in ms. This will make the property update to the current time every x ms. You can then use that property as the source of another binding, or put a change script on it to execute things on a fixed interval.
